* added support for NFC out-of-band mechanism with WPS
* added preliminary support for IEEE 802.11r RIC processing
2009-01-06 - v0.6.7
* added support for Wi-Fi Protected Setup (WPS)
(hostapd can now be configured to act as an integrated WPS Registrar
and provision credentials for WPS Enrollees using PIN and PBC
methods; external wireless Registrar can configure the AP, but
external WLAN Manager Registrars are not supported); WPS support can
be enabled by adding CONFIG_WPS=y into .config and setting the
runtime configuration variables in hostapd.conf (see WPS section in
the example configuration file); new hostapd_cli commands wps_pin and
wps_pbc are used to configure WPS negotiation; see README-WPS for
more details
* added IEEE 802.11n HT capability configuration (ht_capab)
* added support for generating Country IE based on nl80211 regulatory
information (added if ieee80211d=1 in configuration)
* fixed WEP authentication (both Open System and Shared Key) with
mac80211
* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
* added support for using driver_test over UDP socket
* changed EAP-GPSK to use the IANA assigned EAP method type 51
* updated management frame protection to use IEEE 802.11w/D7.0
* fixed retransmission of EAP requests if no response is received
2008-11-23 - v0.6.6
* added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against
TKIP deficiencies
* updated OpenSSL code for EAP-FAST to use an updated version of the
session ticket overriding API that was included into the upstream
OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
needed with that version anymore)
* changed channel flags configuration to read the information from
the driver (e.g., via driver_nl80211 when using mac80211) instead of
using hostapd as the source of the regulatory information (i.e.,
information from CRDA is now used with mac80211); this allows 5 GHz
channels to be used with hostapd (if allowed in the current
regulatory domain)
* fixed EAP-TLS message processing for the last TLS message if it is
large enough to require fragmentation (e.g., if a large Session
Ticket data is included)
* fixed listen interval configuration for nl80211 drivers
2008-11-01 - v0.6.5
* added support for SHA-256 as X.509 certificate digest when using the
internal X.509/TLSv1 implementation
* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
identity lengths)
* fixed internal TLSv1 implementation for abbreviated handshake (used
by EAP-FAST server)
* added support for setting VLAN ID for STAs based on local MAC ACL
(accept_mac_file) as an alternative for RADIUS server-based
configuration
* updated management frame protection to use IEEE 802.11w/D6.0
(adds a new association ping to protect against unauthenticated
authenticate or (re)associate request frames dropping association)
* added support for using SHA256-based stronger key derivation for WPA2
(IEEE 802.11w)
* added new "driver wrapper" for RADIUS-only configuration
(driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
is enabled in configuration
* changed EAP-FAST configuration to use separate fields for A-ID and
A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
16-octet len binary value for better interoperability with some peer
implementations; eap_fast_a_id is now configured as a hex string
* driver_nl80211: Updated to match the current Linux mac80211 AP mode
configuration (wireless-testing.git and Linux kernel releases
starting from 2.6.29)
2008-08-10 - v0.6.4
* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
Identity Request if identity is already known
* added support for EAP Sequences in EAP-FAST Phase 2
* added support for EAP-TNC (Trusted Network Connect)
(this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
changes needed to run two methods in sequence (IF-T) and the IF-IMV
and IF-TNCCS interfaces from TNCS)
* added support for optional cryptobinding with PEAPv0
* added fragmentation support for EAP-TNC
* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
data
* added support for opportunistic key caching (OKC)
2008-02-22 - v0.6.3
* fixed Reassociation Response callback processing when using internal
MLME (driver_{hostap,nl80211,test}.c)
* updated FT support to use the latest draft, IEEE 802.11r/D9.0
* copy optional Proxy-State attributes into RADIUS response when acting
as a RADIUS authentication server
* fixed EAPOL state machine to handle a case in which no response is
received from the RADIUS authentication server; previous version
could have triggered a crash in some cases after a timeout
* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
be used
* added a workaround for EAP-SIM/AKA peers that include incorrect null
termination in the username
* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
attribute in notification messages only when using fast
reauthentication
* fixed EAP-SIM Start response processing for fast reauthentication
case
* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
2008-01-01 - v0.6.2
* fixed EAP-SIM and EAP-AKA message parser to validate attribute
lengths properly to avoid potential crash caused by invalid messages
* added data structure for storing allocated buffers (struct wpabuf);
this does not affect hostapd usage, but many of the APIs changed
and various interfaces (e.g., EAP) is not compatible with old
versions
* added support for protecting EAP-AKA/Identity messages with
AT_CHECKCODE (optional feature in RFC 4187)
* added support for protected result indication with AT_RESULT_IND for
EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
* added support for configuring EAP-TTLS phase 2 non-EAP methods in
EAP server configuration; previously all four were enabled for every
phase 2 user, now all four are disabled by default and need to be
enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
TTLS-MSCHAPV2
* removed old debug printing mechanism and the related 'debug'
parameter in the configuration file; debug verbosity is now set with
-d (or -dd) command line arguments
* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
only shared key/password authentication is supported in this version
2007-11-24 - v0.6.1
* added experimental, integrated TLSv1 server implementation with the
needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
.config); this can be useful, e.g., if the target system does not
have a suitable TLS library and a minimal code size is required
* added support for EAP-FAST server method to the integrated EAP
server
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
draft (draft-ietf-emu-eap-gpsk-07.txt)
* added a new configuration parameter, rsn_pairwise, to allow different
pairwise cipher suites to be enabled for WPA and RSN/WPA2
(note: if wpa_pairwise differs from rsn_pairwise, the driver will
either need to support this or will have to use the WPA/RSN IEs from
hostapd; currently, the included madwifi and bsd driver interfaces do
not have support for this)
* updated FT support to use the latest draft, IEEE 802.11r/D8.0
2007-05-28 - v0.6.0
* added experimental IEEE 802.11r/D6.0 support
* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
* updated EAP-PSK to use the IANA-allocated EAP type 47
* fixed EAP-PSK bit ordering of the Flags field
* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
by reading wpa_psk_file [Bug 181]
* fixed EAP-TTLS AVP parser processing for too short AVP lengths
* fixed IPv6 connection to RADIUS accounting server
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
draft (draft-ietf-emu-eap-gpsk-04.txt)
* hlr_auc_gw: read GSM triplet file into memory and rotate through the
entries instead of only using the same three triplets every time
(this does not work properly with tests using multiple clients, but
provides bit better triplet data for testing a single client; anyway,
if a better quality triplets are needed, GSM-Milenage should be used
instead of hardcoded triplet file)
* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
in Success Request [Bug 203]
* added support for sending EAP-AKA Notifications in error cases
* updated to use IEEE 802.11w/D2.0 for management frame protection
(still experimental)
* RADIUS server: added support for processing duplicate messages
(retransmissions from RADIUS client) by replying with the previous
reply
2006-11-24 - v0.5.6
* added support for configuring and controlling multiple BSSes per
radio interface (bss=<ifname> in hostapd.conf); this is only
available with Devicescape and test driver interfaces
* fixed PMKSA cache update in the end of successful RSN
pre-authentication
* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
for each STA based on RADIUS Access-Accept attributes); this requires
VLAN support from the kernel driver/802.11 stack and this is
currently only available with Devicescape and test driver interfaces
* driver_madwifi: fixed configuration of unencrypted modes (plaintext
and IEEE 802.1X without WEP)
* removed STAKey handshake since PeerKey handshake has replaced it in
IEEE 802.11ma and there are no known deployments of STAKey
* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
draft (draft-ietf-emu-eap-gpsk-01.txt)
* added preliminary implementation of IEEE 802.11w/D1.0 (management
frame protection)
(Note: this requires driver support to work properly.)
(Note2: IEEE 802.11w is an unapproved draft and subject to change.)
* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
parameters from a text file to make it possible to implement proper
GSM/UMTS authentication server for multiple SIM/USIM cards using
EAP-SIM/EAP-AKA
* fixed session timeout processing with drivers that do not use
ieee802_11.c (e.g., madwifi)
2006-08-27 - v0.5.5
* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
hostapd (e.g., to initialize wired network authentication based on an
external signal)
* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
using WPA2 even if PMKSA caching is not used
* added -P<pid file> argument for hostapd to write the current process
id into a file
* added support for RADIUS Authentication Server MIB (RFC 2619)
2006-06-20 - v0.5.4
* fixed nt_password_hash build [Bug 144]
* added PeerKey handshake implementation for IEEE 802.11e
direct link setup (DLS) to replace STAKey handshake
* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
draft-clancy-emu-eap-shared-secret-00.txt)
* fixed a segmentation fault when RSN pre-authentication was completed
successfully [Bug 152]
2006-04-27 - v0.5.3
* do not build nt_password_hash and hlr_auc_gw by default to avoid
requiring a TLS library for a successful build; these programs can be
build with 'make nt_password_hash' and 'make hlr_auc_gw'
* added a new configuration option, eapol_version, that can be used to
set EAPOL version to 1 (default is 2) to work around broken client
implementations that drop EAPOL frames which use version number 2
[Bug 89]
* added support for EAP-SAKE (no EAP method number allocated yet, so
this is using the same experimental type 255 as EAP-PSK)
* fixed EAP-MSCHAPv2 message length validation
2006-03-19 - v0.5.2
* fixed stdarg use in hostapd_logger(): if both stdout and syslog
logging was enabled, hostapd could trigger a segmentation fault in
vsyslog on some CPU -- C library combinations
* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
program to make it easier to use for implementing real SS7 gateway;
eap_sim_db is not anymore used as a file name for GSM authentication
triplets; instead, it is path to UNIX domain socket that will be used
to communicate with the external gateway program (e.g., hlr_auc_gw)
* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
local information (GSM authentication triplets from a text file and
hardcoded AKA authentication data); this can be used to test EAP-SIM
and EAP-AKA
* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
to make it possible to test EAP-AKA with real USIM cards (this is
disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
to enable this)
* driver_madwifi: added support for getting station RSN IE from
madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
broken with earlier change (r1357) in the driver
* changed EAP method registration to use a dynamic list of methods
instead of a static list generated at build time
* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
[Bug 125]
* added ap_max_inactivity configuration parameter
2006-01-29 - v0.5.1
* driver_test: added better support for multiple APs and STAs by using
a directory with sockets that include MAC address for each device in
the name (test_socket=DIR:/tmp/test)
* added support for EAP expanded type (vendor specific EAP methods)
2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
* added experimental STAKey handshake implementation for IEEE 802.11e
direct link setup (DLS); note: this is disabled by default in both
build and runtime configuration (can be enabled with CONFIG_STAKEY=y
and stakey=1)
* added support for EAP methods to use callbacks to external programs
by buffering a pending request and processing it after the EAP method
is ready to continue
* improved EAP-SIM database interface to allow external request to GSM
HLR/AuC without blocking hostapd process
* added support for using EAP-SIM pseudonyms and fast re-authentication
* added support for EAP-AKA in the integrated EAP authenticator
* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
user database to allow EAP-SIM/AKA selection without extra roundtrip
for EAP-Nak negotiation
* added support for storing EAP user password as NtPasswordHash instead
of plaintext password when using MSCHAP or MSCHAPv2 for
authentication (hash:<16-octet hex value>); added nt_password_hash
tool for hashing password to generate NtPasswordHash
2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
* driver_wired: fixed EAPOL sending to optionally use PAE group address
as the destination instead of supplicant MAC address; this is
disabled by default, but should be enabled with use_pae_group_addr=1
in configuration file if the wired interface is used by only one
device at the time (common switch configuration)
* driver_madwifi: configure driver to use TKIP countermeasures in order
to get correct behavior (IEEE 802.11 association failing; previously,
association succeeded, but hostpad forced disassociation immediately)
* driver_madwifi: added support for madwifi-ng
2005-10-27 - v0.4.6
* added support for replacing user identity from EAP with RADIUS
User-Name attribute from Access-Accept message, if that is included,
for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
tunneled identity into accounting messages when the RADIUS server
does not support better way of doing this with Class attribute)
* driver_madwifi: fixed EAPOL packet receive for configuration where
ath# is part of a bridge interface
* added a configuration file and log analyzer script for logwatch
* fixed EAPOL state machine step function to process all state
transitions before processing new events; this resolves a race
condition in which EAPOL-Start message could trigger hostapd to send
two EAP-Response/Identity frames to the authentication server
2005-09-25 - v0.4.5
* added client CA list to the TLS certificate request in order to make
it easier for the client to select which certificate to use
* added experimental support for EAP-PSK
* added support for WE-19 (hostap, madwifi)
2005-08-21 - v0.4.4
* fixed build without CONFIG_RSN_PREAUTH
* fixed FreeBSD build
2005-06-26 - v0.4.3
* fixed PMKSA caching to copy User-Name and Class attributes so that
RADIUS accounting gets correct information
* start RADIUS accounting only after successful completion of WPA
4-Way Handshake if WPA-PSK is used
* fixed PMKSA caching for the case where STA (re)associates without
first disassociating
2005-06-12 - v0.4.2
* EAP-PAX is now registered as EAP type 46
* fixed EAP-PAX MAC calculation
* fixed EAP-PAX CK and ICK key derivation
* renamed eap_authenticator configuration variable to eap_server to
better match with RFC 3748 (EAP) terminology
* driver_test: added support for testing hostapd with wpa_supplicant
by using test driver interface without any kernel drivers or network
cards
2005-05-22 - v0.4.1
* fixed RADIUS server initialization when only auth or acct server
is configured and the other one is left empty
* driver_madwifi: added support for RADIUS accounting
* driver_madwifi: added preliminary support for compiling against 'BSD'
branch of madwifi CVS tree
* driver_madwifi: fixed pairwise key removal to allow WPA reauth
without disassociation
* added support for reading additional certificates from PKCS#12 files
and adding them to the certificate chain
* fixed RADIUS Class attribute processing to only use Access-Accept
packets to update Class; previously, other RADIUS authentication
packets could have cleared Class attribute
* added support for more than one Class attribute in RADIUS packets
* added support for verifying certificate revocation list (CRL) when
using integrated EAP authenticator for EAP-TLS; new hostapd.conf
options 'check_crl'; CRL must be included in the ca_cert file for now
2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
* added support for including network information into
EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
(e.g., to implement draft-adrange-eap-network-discovery-07.txt)
* fixed a bug which caused some RSN pre-authentication cases to use
freed memory and potentially crash hostapd
* fixed private key loading for cases where passphrase is not set
* added support for sending TLS alerts and aborting authentication
when receiving a TLS alert
* fixed WPA2 to add PMKSA cache entry when using integrated EAP
authenticator
* fixed PMKSA caching (EAP authentication was not skipped correctly
with the new state machine changes from IEEE 802.1X draft)
* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
to be added to .config to include IPv6 support); for RADIUS server,
radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
in RADIUS clients file can then use IPv6 format
* added experimental support for EAP-PAX
* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
2005-01-23 - v0.3.5
* added support for configuring a forced PEAP version based on the
Phase 1 identity
* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
to terminate authentication
* fixed EAP identifier duplicate processing with the new IEEE 802.1X
draft
* clear accounting data in the driver when starting a new accounting
session
* driver_madwifi: filter wireless events based on ifindex to allow more
than one network interface to be used
* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
setting if the packet does not pass MIC verification (e.g., due to
incorrect PSK); previously, message 1/4 was not tried again if an
invalid message 2/4 was received
* fixed reconfiguration of RADIUS client retransmission timer when
adding a new message to the pending list; previously, timer was not
updated at this point and if there was a pending message with long
time for the next retry, the new message needed to wait that long for
its first retry, too
2005-01-09 - v0.3.4
* added support for configuring multiple allowed EAP types for Phase 2
authentication (EAP-PEAP, EAP-TTLS)
* fixed EAPOL-Start processing to trigger WPA reauthentication
(previously, only EAPOL authentication was done)
2005-01-02 - v0.3.3
* added support for EAP-PEAP in the integrated EAP authenticator
* added support for EAP-GTC in the integrated EAP authenticator
* added support for configuring list of EAP methods for Phase 1 so that
the integrated EAP authenticator can, e.g., use the wildcard entry
for EAP-TLS and EAP-PEAP
* added support for EAP-TTLS in the integrated EAP authenticator
* added support for EAP-SIM in the integrated EAP authenticator
* added support for using hostapd as a RADIUS authentication server
with the integrated EAP authenticator taking care of EAP
authentication (new hostapd.conf options: radius_server_clients and
radius_server_auth_port); this is not included in default build; use
CONFIG_RADIUS_SERVER=y in .config to include
2004-12-19 - v0.3.2
* removed 'daemonize' configuration file option since it has not really
been used at all for more than year
* driver_madwifi: fixed group key setup and added get_ssid method
* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
2004-12-12 - v0.3.1
* added support for integrated EAP-TLS authentication (new hostapd.conf
variables: ca_cert, server_cert, private_key, private_key_passwd);
this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
external RADIUS server
* added support for reading PKCS#12 (PFX) files (as a replacement for
PEM/DER) to get certificate and private key (CONFIG_PKCS12)
2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
* added support for Acct-{Input,Output}-Gigawords
* added support for Event-Timestamp (in RADIUS Accounting-Requests)
* added support for RADIUS Authentication Client MIB (RFC2618)
* added support for RADIUS Accounting Client MIB (RFC2620)
* made EAP re-authentication period configurable (eap_reauth_period)
* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
* fixed EAPOL state machine to stop if STA is removed during
eapol_sm_step(); this fixes at least one segfault triggering bug with
IEEE 802.11i pre-authentication
* added support for multiple WPA pre-shared keys (e.g., one for each
client MAC address or keys shared by a group of clients);
new hostapd.conf field wpa_psk_file for setting path to a text file
containing PSKs, see hostapd.wpa_psk for an example
* added support for multiple driver interfaces to allow hostapd to be
used with other drivers
* added wired authenticator driver interface (driver=wired in
hostapd.conf, see wired.conf for example configuration)
* added madwifi driver interface (driver=madwifi in hostapd.conf, see
madwifi.conf for example configuration; Note: include files from
madwifi project is needed for building and a configuration file,
.config, needs to be created in hostapd directory with
CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
build)
* fixed an alignment issue that could cause SHA-1 to fail on some
platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
align variables)
* fixed RADIUS reconnection after an error in sending interim
accounting packets
* added hostapd control interface for external programs and an example
CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
'hostapd_cli sta <addr>')
* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
* added support for strict GTK rekeying (wpa_strict_rekey in
hostapd.conf)
* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
(instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
IEEE 802.11F-2003)
* added Prism54 driver interface (driver=prism54 in hostapd.conf;
note: .config needs to be created in hostapd directory with
CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
build)
* dual-licensed hostapd (GPLv2 and BSD licenses)
* fixed RADIUS accounting to generate a new session id for cases where
a station reassociates without first being complete deauthenticated
* fixed STA disassociation handler to mark next timeout state to
deauthenticate the station, i.e., skip long wait for inactivity poll
and extra disassociation, if the STA disassociates without
deauthenticating
* added integrated EAP authenticator that can be used instead of
external RADIUS authentication server; currently, only EAP-MD5 is
supported, so this cannot yet be used for key distribution; the EAP
method interface is generic, though, so adding new EAP methods should
be straightforward; new hostapd.conf variables: 'eap_authenticator'
and 'eap_user_file'; this obsoletes "minimal authentication server"
('minimal_eap' in hostapd.conf) which is now removed
* added support for FreeBSD and driver interface for the BSD net80211
layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
.config); please note that some of the required kernel mods have not
yet been committed
2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
* fixed some accounting cases where Accounting-Start was sent when
IEEE 802.1X port was being deauthorized
2004-06-20 - v0.2.3
* modified RADIUS client to re-connect the socket in case of certain
error codes that are generated when a network interface state is
changes (e.g., when IP address changes or the interface is set UP)
* fixed couple of cases where EAPOL state for a station was freed
twice causing a segfault for hostapd
* fixed couple of bugs in processing WPA deauthentication (freed data
was used)
2004-05-31 - v0.2.2
* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
cases where STAs dropped multicast frames as replay attacks
* added support for copying RADIUS Attribute 'Class' from
authentication messages into accounting messages
* send canned EAP failure if RADIUS server sends Access-Reject without
EAP message (previously, Supplicant was not notified in this case)
* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
not start EAPOL state machines if the STA selected to use WPA-PSK)
2004-05-06 - v0.2.1
* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
- based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
(i.e., IEEE 802.11i/D3.0)
- supports WPA-only, RSN-only, and mixed WPA/RSN mode
- both WPA-PSK and WPA-RADIUS/EAP are supported
- PMKSA caching and pre-authentication
- new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
rsn_preauth, rsn_preauth_interfaces
* fixed interim accounting to remove any pending accounting messages
to the STA before sending a new one
2004-02-15 - v0.2.0
* added support for Acct-Interim-Interval:
- draft-ietf-radius-acct-interim-01.txt
- use Acct-Interim-Interval attribute from Access-Accept if local
'radius_acct_interim_interval' is not set
- allow different update intervals for each STA
* fixed event loop to call signal handlers only after returning from
the real signal handler
* reset sta->timeout_next after successful association to make sure
that the previously registered inactivity timer will not remove the
STA immediately (e.g., if STA deauthenticates and re-associates
before the timer is triggered).
* added new hostapd.conf variable, nas_identifier, that can be used to
add an optional RADIUS Attribute, NAS-Identifier, into authentication
and accounting messages
* added support for Accounting-On and Accounting-Off messages
* fixed accounting session handling to send Accounting-Start only once
per session and not to send Accounting-Stop if the session was not
initialized properly
* fixed Accounting-Stop statistics in cases where the message was
previously sent after the kernel entry for the STA (and/or IEEE
802.1X data) was removed
Note:
Older changes up to and including v0.1.0 are included in the ChangeLog
of the Host AP driver.

Introduction
============
Originally, hostapd was an optional user space component for Host AP
driver. It adds more features to the basic IEEE 802.11 management
included in the kernel driver: using external RADIUS authentication
server for MAC address based access control, IEEE 802.1X Authenticator
and dynamic WEP keying, RADIUS accounting, WPA/WPA2 (IEEE 802.11i/RSN)
Authenticator and dynamic TKIP/CCMP keying.
The current version includes support for other drivers, an integrated
EAP server (i.e., allow full authentication without requiring
an external RADIUS authentication server), and RADIUS authentication
server for EAP authentication.
Requirements
------------
Current hardware/software requirements:
- drivers:
Host AP driver for Prism2/2.5/3.
(http://hostap.epitest.fi/)
Please note that station firmware version needs to be 1.7.0 or newer
to work in WPA mode.
madwifi driver for cards based on Atheros chip set (ar521x)
(http://sourceforge.net/projects/madwifi/)
Please note that you will need to add the correct path for
madwifi driver root directory in .config (see defconfig file for
an example: CFLAGS += -I<path>)
mac80211-based drivers that support AP mode (with driver=nl80211).
This includes drivers for Atheros (ath9k) and Broadcom (b43)
chipsets.
Any wired Ethernet driver for wired IEEE 802.1X authentication
(experimental code)
FreeBSD -current (with some kernel mods that have not yet been
committed when hostapd v0.3.0 was released)
BSD net80211 layer (e.g., Atheros driver)
Build configuration
-------------------
In order to be able to build hostapd, you will need to create a build
time configuration file, .config that selects which optional
components are included. See defconfig file for example configuration
and list of available options.
IEEE 802.1X
===========
IEEE Std 802.1X-2001 is a standard for port-based network access
control. In case of IEEE 802.11 networks, a "virtual port" is used
between each associated station and the AP. IEEE 802.11 specifies
minimal authentication mechanism for stations, whereas IEEE 802.1X
introduces a extensible mechanism for authenticating and authorizing
users.
IEEE 802.1X uses elements called Supplicant, Authenticator, Port
Access Entity, and Authentication Server. Supplicant is a component in
a station and it performs the authentication with the Authentication
Server. An access point includes an Authenticator that relays the packets
between a Supplicant and an Authentication Server. In addition, it has a
Port Access Entity (PAE) with Authenticator functionality for
controlling the virtual port authorization, i.e., whether to accept
packets from or to the station.
IEEE 802.1X uses Extensible Authentication Protocol (EAP). The frames
between a Supplicant and an Authenticator are sent using EAP over LAN
(EAPOL) and the Authenticator relays these frames to the Authentication
Server (and similarly, relays the messages from the Authentication
Server to the Supplicant). The Authentication Server can be colocated with the
Authenticator, in which case there is no need for additional protocol
for EAP frame transmission. However, a more common configuration is to
use an external Authentication Server and encapsulate EAP frame in the
frames used by that server. RADIUS is suitable for this, but IEEE
802.1X would also allow other mechanisms.
Host AP driver includes PAE functionality in the kernel driver. It
is a relatively simple mechanism for denying normal frames going to
or coming from an unauthorized port. PAE allows IEEE 802.1X related
frames to be passed between the Supplicant and the Authenticator even
on an unauthorized port.
User space daemon, hostapd, includes Authenticator functionality. It
receives 802.1X (EAPOL) frames from the Supplicant using the wlan#ap
device that is also used with IEEE 802.11 management frames. The
frames to the Supplicant are sent using the same device.
The normal configuration of the Authenticator would use an external
Authentication Server. hostapd supports RADIUS encapsulation of EAP
packets, so the Authentication Server should be a RADIUS server, like
FreeRADIUS (http://www.freeradius.org/). The Authenticator in hostapd
relays the frames between the Supplicant and the Authentication
Server. It also controls the PAE functionality in the kernel driver by
controlling virtual port authorization, i.e., station-AP
connection, based on the IEEE 802.1X state.
When a station would like to use the services of an access point, it
will first perform IEEE 802.11 authentication. This is normally done
with open systems authentication, so there is no security. After
this, IEEE 802.11 association is performed. If IEEE 802.1X is
configured to be used, the virtual port for the station is set in
Unauthorized state and only IEEE 802.1X frames are accepted at this
point. The Authenticator will then ask the Supplicant to authenticate
with the Authentication Server. After this is completed successfully,
the virtual port is set to Authorized state and frames from and to the
station are accepted.
Host AP configuration for IEEE 802.1X
-------------------------------------
The user space daemon has its own configuration file that can be used to
define AP options. Distribution package contains an example
configuration file (hostapd/hostapd.conf) that can be used as a basis
for configuration. It includes examples of all supported configuration
options and short description of each option. hostapd should be started
with full path to the configuration file as the command line argument,
e.g., './hostapd /etc/hostapd.conf'. If you have more that one wireless
LAN card, you can use one hostapd process for multiple interfaces by
giving a list of configuration files (one per interface) in the command
line.
hostapd includes a minimal co-located IEEE 802.1X server which can be
used to test IEEE 802.1X authentication. However, it should not be
used in normal use since it does not provide any security. This can be
configured by setting ieee8021x and minimal_eap options in the
configuration file.
An external Authentication Server (RADIUS) is configured with
auth_server_{addr,port,shared_secret} options. In addition,
ieee8021x and own_ip_addr must be set for this mode. With such
configuration, the co-located Authentication Server is not used and EAP
frames will be relayed using EAPOL between the Supplicant and the
Authenticator and RADIUS encapsulation between the Authenticator and
the Authentication Server. Other than this, the functionality is similar
to the case with the co-located Authentication Server.
Authentication Server and Supplicant
------------------------------------
Any RADIUS server supporting EAP should be usable as an IEEE 802.1X
Authentication Server with hostapd Authenticator. FreeRADIUS
(http://www.freeradius.org/) has been successfully tested with hostapd
Authenticator and both Xsupplicant (http://www.open1x.org) and Windows
XP Supplicants. EAP/TLS was used with Xsupplicant and
EAP/MD5-Challenge with Windows XP.
http://www.missl.cs.umd.edu/wireless/eaptls/ has useful information
about using EAP/TLS with FreeRADIUS and Xsupplicant (just replace
Cisco access point with Host AP driver, hostapd daemon, and a Prism2
card ;-). http://www.freeradius.org/doc/EAP-MD5.html has information
about using EAP/MD5 with FreeRADIUS, including instructions for WinXP
configuration. http://www.denobula.com/EAPTLS.pdf has a HOWTO on
EAP/TLS use with WinXP Supplicant.
Automatic WEP key configuration
-------------------------------
EAP/TLS generates a session key that can be used to send WEP keys from
an AP to authenticated stations. The Authenticator in hostapd can be
configured to automatically select a random default/broadcast key
(shared by all authenticated stations) with wep_key_len_broadcast
option (5 for 40-bit WEP or 13 for 104-bit WEP). In addition,
wep_key_len_unicast option can be used to configure individual unicast
keys for stations. This requires support for individual keys in the
station driver.
WEP keys can be automatically updated by configuring rekeying. This
will improve security of the network since same WEP key will only be
used for a limited period of time. wep_rekey_period option sets the
interval for rekeying in seconds.
WPA/WPA2
========
Features
--------
Supported WPA/IEEE 802.11i features:
- WPA-PSK ("WPA-Personal")
- WPA with EAP (e.g., with RADIUS authentication server) ("WPA-Enterprise")
- key management for CCMP, TKIP, WEP104, WEP40
- RSN/WPA2 (IEEE 802.11i), including PMKSA caching and pre-authentication
WPA
---
The original security mechanism of IEEE 802.11 standard was not
designed to be strong and has proved to be insufficient for most
networks that require some kind of security. Task group I (Security)
of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
to address the flaws of the base standard and has in practice
completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
802.11 standard was approved in June 2004 and this amendment is likely
to be published in July 2004.
Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
IEEE 802.11i work (draft 3.0) to define a subset of the security
enhancements that can be implemented with existing wlan hardware. This
is called Wi-Fi Protected Access<TM> (WPA). This has now become a
mandatory component of interoperability testing and certification done
by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
site (http://www.wi-fi.org/OpenSection/protected_access.asp).
IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
for protecting wireless networks. WEP uses RC4 with 40-bit keys,
24-bit initialization vector (IV), and CRC32 to protect against packet
forgery. All these choices have proven to be insufficient: key space is
too small against current attacks, RC4 key scheduling is insufficient
(beginning of the pseudorandom stream should be skipped), IV space is
too small and IV reuse makes attacks easier, there is no replay
protection, and non-keyed authentication does not protect against bit
flipping packet data.
WPA is an intermediate solution for the security issues. It uses
Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
compromise on strong security and possibility to use existing
hardware. It still uses RC4 for the encryption like WEP, but with
per-packet RC4 keys. In addition, it implements replay protection,
keyed packet authentication mechanism (Michael MIC).
Keys can be managed using two different mechanisms. WPA can either use
an external authentication server (e.g., RADIUS) and EAP just like
IEEE 802.1X is using or pre-shared keys without need for additional
servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
respectively. Both mechanisms will generate a master session key for
the Authenticator (AP) and Supplicant (client station).
WPA implements a new key handshake (4-Way Handshake and Group Key
Handshake) for generating and exchanging data encryption keys between
the Authenticator and Supplicant. This handshake is also used to
verify that both Authenticator and Supplicant know the master session
key. These handshakes are identical regardless of the selected key
management mechanism (only the method for generating master session
key changes).
IEEE 802.11i / WPA2
-------------------
The design for parts of IEEE 802.11i that were not included in WPA has
finished (May 2004) and this amendment to IEEE 802.11 was approved in
June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
version of WPA called WPA2. This includes, e.g., support for more
robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
to replace TKIP and optimizations for handoff (reduced number of
messages in initial key handshake, pre-authentication, and PMKSA caching).
Some wireless LAN vendors are already providing support for CCMP in
their WPA products. There is no "official" interoperability
certification for CCMP and/or mixed modes using both TKIP and CCMP, so
some interoperability issues can be expected even though many
combinations seem to be working with equipment from different vendors.
Testing for WPA2 is likely to start during the second half of 2004.

hostapd and Wi-Fi Protected Setup (WPS)
=======================================
This document describes how the WPS implementation in hostapd can be
configured and how an external component on an AP (e.g., web UI) is
used to enable enrollment of client devices.
Introduction to WPS
-------------------
Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
wireless network. It allows automated generation of random keys (WPA
passphrase/PSK) and configuration of an access point and client
devices. WPS includes number of methods for setting up connections
with PIN method and push-button configuration (PBC) being the most
commonly deployed options.
While WPS can enable more home networks to use encryption in the
wireless network, it should be noted that the use of the PIN and
especially PBC mechanisms for authenticating the initial key setup is
not very secure. As such, use of WPS may not be suitable for
environments that require secure network access without chance for
allowing outsiders to gain access during the setup phase.
WPS uses following terms to describe the entities participating in the
network setup:
- access point: the WLAN access point
- Registrar: a device that control a network and can authorize
addition of new devices); this may be either in the AP ("internal
Registrar") or in an external device, e.g., a laptop, ("external
Registrar")
- Enrollee: a device that is being authorized to use the network
It should also be noted that the AP and a client device may change
roles (i.e., AP acts as an Enrollee and client device as a Registrar)
when WPS is used to configure the access point.
More information about WPS is available from Wi-Fi Alliance:

hostapd implementation
----------------------
hostapd includes an optional WPS component that can be used as an
internal WPS Registrar to manage addition of new WPS enabled clients
to the network. In addition, WPS Enrollee functionality in hostapd can
be used to allow external WPS Registrars to configure the access
point, e.g., for initial network setup. In addition, hostapd can proxy a
WPS registration between a wireless Enrollee and an external Registrar
(e.g., Microsoft Vista or Atheros JumpStart) with UPnP.
hostapd configuration
---------------------
WPS is an optional component that needs to be enabled in hostapd build
configuration (.config). Here is an example configuration that
includes WPS support and uses madwifi driver interface:
CONFIG_DRIVER_MADWIFI=y
CFLAGS += -I/usr/src/madwifi-0.9.3
CONFIG_WPS=y
CONFIG_WPS_UPNP=y
Following section shows an example runtime configuration
(hostapd.conf) that enables WPS:
# Configure the driver and network interface
driver=madwifi
interface=ath0
# WPA2-Personal configuration for the AP
ssid=wps-test
wpa=2
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
# Default WPA passphrase for legacy (non-WPS) clients
wpa_passphrase=12345678
# Enable random per-device PSK generation for WPS clients
# Please note that the file has to exists for hostapd to start (i.e., create an
# empty file as a starting point).
wpa_psk_file=/etc/hostapd.psk
# Enable control interface for PBC/PIN entry
ctrl_interface=/var/run/hostapd
# Enable internal EAP server for EAP-WSC (part of Wi-Fi Protected Setup)
eap_server=1
# WPS configuration (AP configured, do not allow external WPS Registrars)
wps_state=2
ap_setup_locked=1
# If UUID is not configured, it will be generated based on local MAC address.
uuid=87654321-9abc-def0-1234-56789abc0000
wps_pin_requests=/var/run/hostapd.pin-req
device_name=Wireless AP
manufacturer=Company
model_name=WAP
model_number=123
serial_number=12345
device_type=6-0050F204-1
os_version=01020300
config_methods=label display push_button keypad
# if external Registrars are allowed, UPnP support could be added:
#upnp_iface=br0
#friendly_name=WPS Access Point
External operations
-------------------
WPS requires either a device PIN code (usually, 8-digit number) or a
pushbutton event (for PBC) to allow a new WPS Enrollee to join the
network. hostapd uses the control interface as an input channel for
these events.
When a client device (WPS Enrollee) connects to hostapd (WPS
Registrar) in order to start PIN mode negotiation for WPS, an
identifier (Enrollee UUID) is sent. hostapd will need to be configured
with a device password (PIN) for this Enrollee. This is an operation
that requires user interaction (assuming there are no pre-configured
PINs on the AP for a set of Enrollee).
The PIN request with information about the device is appended to the
wps_pin_requests file (/var/run/hostapd.pin-req in this example). In
addition, hostapd control interface event is sent as a notification of
a new device. The AP could use, e.g., a web UI for showing active
Enrollees to the user and request a PIN for an Enrollee.
The PIN request file has one line for every Enrollee that connected to
the AP, but for which there was no PIN. Following information is
provided for each Enrollee (separated with tabulators):
- timestamp (seconds from 1970-01-01)
- Enrollee UUID
- MAC address
- Device name
- Manufacturer
- Model Name
- Model Number
- Serial Number
- Device category
Example line in the /var/run/hostapd.pin-req file:
1200188391 53b63a98-d29e-4457-a2ed-094d7e6a669c Intel(R) Centrino(R) Intel Corporation Intel(R) Centrino(R) - - 1-0050F204-1
Control interface data:
WPS-PIN-NEEDED [UUID-E|MAC Address|Device Name|Manufacturer|Model Name|Model Number|Serial Number|Device Category]
For example:
<2>WPS-PIN-NEEDED [53b63a98-d29e-4457-a2ed-094d7e6a669c|02:12:34:56:78:9a|Device|Manuf|Model|Model Number|Serial Number|1-0050F204-1]
When the user enters a PIN for a pending Enrollee, e.g., on the web
UI), hostapd needs to be notified of the new PIN over the control
interface. This can be done either by using the UNIX domain socket
-based control interface directly (src/common/wpa_ctrl.c provides
helper functions for using the interface) or by calling hostapd_cli.
Example command to add a PIN (12345670) for an Enrollee:
hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c 12345670
If the UUID-E is not available (e.g., Enrollee waits for the Registrar
to be selected before connecting), wildcard UUID may be used to allow
the PIN to be used once with any UUID:
hostapd_cli wps_pin any 12345670
To reduce likelihood of PIN being used with other devices or of
forgetting an active PIN available for potential attackers, expiration
time can be set for the new PIN:
hostapd_cli wps_pin any 12345670 300
After this, the Enrollee can connect to the AP again and complete WPS
negotiation. At that point, a new, random WPA PSK is generated for the
client device and the client can then use that key to connect to the
AP to access the network.
If the AP includes a pushbutton, WPS PBC mode can be used. It is
enabled by pushing a button on both the AP and the client at about the
same time (2 minute window). hostapd needs to be notified about the AP
button pushed event over the control interface, e.g., by calling
hostapd_cli:
hostapd_cli wps_pbc
At this point, the client has two minutes to complete WPS negotiation
which will generate a new WPA PSK in the same way as the PIN method
described above.
When an external Registrar is used, the AP can act as an Enrollee and
use its AP PIN. A static AP PIN (e.g., one one a label in the AP
device) can be configured in hostapd.conf (ap_pin parameter). A more
secure option is to use hostapd_cli wps_ap_pin command to enable the
AP PIN only based on user action (and even better security by using a
random AP PIN for each session, i.e., by using "wps_ap_pin random"
command with a timeout value). Following commands are available for
managing the dynamic AP PIN operations:
hostapd_cli wps_ap_pin disable
- disable AP PIN (i.e., do not allow external Registrars to use it to
learn the current AP settings or to reconfigure the AP)
hostapd_cli wps_ap_pin random [timeout]
- generate a random AP PIN and enable it
- if the optional timeout parameter is given, the AP PIN will be enabled
for the specified number of seconds
hostapd_cli wps_ap_pin get
- fetch the current AP PIN
hostapd_cli wps_ap_pin set <PIN> [timeout]
- set the AP PIN and enable it
- if the optional timeout parameter is given, the AP PIN will be enabled
for the specified number of seconds
Credential generation and configuration changes
-----------------------------------------------
By default, hostapd generates credentials for Enrollees and processing
AP configuration updates internally. However, it is possible to
control these operations from external programs, if desired.
The internal credential generation can be disabled with
skip_cred_build=1 option in the configuration. extra_cred option will
then need to be used to provide pre-configured Credential attribute(s)
for hostapd to use. The exact data from this binary file will be sent,
i.e., it will have to include valid WPS attributes. extra_cred can
also be used to add additional networks if the Registrar is used to
configure credentials for multiple networks.
Processing of received configuration updates can be disabled with
wps_cred_processing=1 option. When this is used, an external program
is responsible for creating hostapd configuration files and processing
configuration updates based on messages received from hostapd over
control interface. This will also include the initial configuration on
first successful registration if the AP is initially set in
unconfigured state.
Following control interface messages are sent out for external programs:
WPS-REG-SUCCESS <Enrollee MAC address <UUID-E>
For example:
<2>WPS-REG-SUCCESS 02:66:a0:ee:17:27 2b7093f1-d6fb-5108-adbb-bea66bb87333
This can be used to tricker change from unconfigured to configured
state (random configuration based on the first successful WPS
registration). In addition, this can be used to update AP UI about the
status of WPS registration progress.
WPS-NEW-AP-SETTINGS <hexdump of AP Setup attributes>
For example:
<2>WPS-NEW-AP-SETTINGS 10260001011045000c6a6b6d2d7770732d74657374100300020020100f00020008102700403065346230343536633236366665306433396164313535346131663462663731323433376163666462376633393965353466316631623032306164343438623510200006024231cede15101e000844
This can be used to update the externally stored AP configuration and
then update hostapd configuration (followed by restarting of hostapd).

* HLR/AuC testing gateway for hostapd EAP-SIM/AKA database/authenticator
* Copyright (c) 2005-2007, Jouni Malinen <j@w1.fi>
*

*
* This is an example implementation of the EAP-SIM/AKA database/authentication
* gateway interface to HLR/AuC. It is expected to be replaced with an
* implementation of SS7 gateway to GSM/UMTS authentication center (HLR/AuC) or
* a local implementation of SIM triplet and AKA authentication data generator.
*
* hostapd will send SIM/AKA authentication queries over a UNIX domain socket
* to and external program, e.g., this hlr_auc_gw. This interface uses simple
* text-based format:
*
* EAP-SIM / GSM triplet query/response:
* SIM-REQ-AUTH <IMSI> <max_chal>
* SIM-RESP-AUTH <IMSI> Kc1:SRES1:RAND1 Kc2:SRES2:RAND2 [Kc3:SRES3:RAND3]
* SIM-RESP-AUTH <IMSI> FAILURE
*
* EAP-AKA / UMTS query/response:
* AKA-REQ-AUTH <IMSI>
* AKA-RESP-AUTH <IMSI> <RAND> <AUTN> <IK> <CK> <RES>
* AKA-RESP-AUTH <IMSI> FAILURE
*
* EAP-AKA / UMTS AUTS (re-synchronization):
* AKA-AUTS <IMSI> <AUTS> <RAND>
*
* IMSI and max_chal are sent as an ASCII string,
* Kc/SRES/RAND/AUTN/IK/CK/RES/AUTS as hex strings.
*
* The example implementation here reads GSM authentication triplets from a
* text file in IMSI:Kc:SRES:RAND format, IMSI in ASCII, other fields as hex
* strings. This is used to simulate an HLR/AuC. As such, it is not very useful
* for real life authentication, but it is useful both as an example
* implementation and for EAP-SIM testing.

.TH HOSTAPD 8 "April 7, 2005" hostapd hostapd
.SH NAME
hostapd \- IEEE 802.11 AP, IEEE 802.1X/WPA/WPA2/EAP/RADIUS Authenticator
.SH SYNOPSIS
.B hostapd
[\-hdBKtv] [\-P <PID file>] <configuration file(s)>
.SH DESCRIPTION
This manual page documents briefly the
.B hostapd
daemon.
.PP
.B hostapd
is a user space daemon for access point and authentication servers.
It implements IEEE 802.11 access point management, IEEE 802.1X/WPA/WPA2/EAP Authenticators and RADIUS authentication server.
The current version supports Linux (Host AP, madwifi, mac80211-based drivers) and FreeBSD (net80211).
.B hostapd
is designed to be a "daemon" program that runs in the background and acts as the backend component controlling authentication.
.B hostapd
supports separate frontend programs and an example text-based frontend,
.BR hostapd_cli ,
is included with
.BR hostapd .
.SH OPTIONS
A summary of options is included below.
For a complete description, run
.BR hostapd
from the command line.

# hostapd user database for integrated EAP server
# Each line must contain an identity, EAP method(s), and an optional password
# separated with whitespace (space or tab). The identity and password must be
# double quoted ("user"). Password can alternatively be stored as
# NtPasswordHash (16-byte MD4 hash of the unicode presentation of the password
# in unicode) if it is used for MSCHAP or MSCHAPv2 authentication. This means
# that the plaintext password does not need to be included in the user file.
# Password hash is stored as hash:<16-octets of hex data> without quotation
# marks.
# [2] flag in the end of the line can be used to mark users for tunneled phase
# 2 authentication (e.g., within EAP-PEAP). In these cases, an anonymous
# identity can be used in the unencrypted phase 1 and the real user identity
# is transmitted only within the encrypted tunnel in phase 2. If non-anonymous
# access is needed, two user entries is needed, one for phase 1 and another
# with the same username for phase 2.
#
# EAP-TLS, EAP-PEAP, EAP-TTLS, EAP-FAST, EAP-SIM, and EAP-AKA do not use
# password option.
# EAP-MD5, EAP-MSCHAPV2, EAP-GTC, EAP-PAX, EAP-PSK, and EAP-SAKE require a
# password.
# EAP-PEAP, EAP-TTLS, and EAP-FAST require Phase 2 configuration.
#
# * can be used as a wildcard to match any user identity. The main purposes for
# this are to set anonymous phase 1 identity for EAP-PEAP and EAP-TTLS and to
# avoid having to configure every certificate for EAP-TLS authentication. The
# first matching entry is selected, so * should be used as the last phase 1
# user entry.
#
# "prefix"* can be used to match the given prefix and anything after this. The
# main purpose for this is to be able to avoid EAP method negotiation when the
# method is using known prefix in identities (e.g., EAP-SIM and EAP-AKA). This
# is only allowed for phase 1 identities.
#
# Multiple methods can be configured to make the authenticator try them one by
# one until the peer accepts one. The method names are separated with a
# comma (,).
#
# [ver=0] and [ver=1] flags after EAP type PEAP can be used to force PEAP
# version based on the Phase 1 identity. Without this flag, the EAP
# authenticator advertises the highest supported version and select the version
# based on the first PEAP packet from the supplicant.
#
# EAP-TTLS supports both EAP and non-EAP authentication inside the tunnel.
# Tunneled EAP methods are configured with standard EAP method name and [2]
# flag. Non-EAP methods can be enabled by following method names: TTLS-PAP,
# TTLS-CHAP, TTLS-MSCHAP, TTLS-MSCHAPV2. TTLS-PAP and TTLS-CHAP require a
# plaintext password while TTLS-MSCHAP and TTLS-MSCHAPV2 can use NT password
