Commit b7f05445c0 has added WWW entries to port Makefiles based on
WWW: lines in pkg-descr files.
This commit removes the WWW: lines of moved-over URLs from these
pkg-descr files.

This is an easy-to-use implementation of ECC (Elliptic Curve Cryptography) with
|
|
support for ECDSA (Elliptic Curve Digital Signature Algorithm) and ECDH
|
|
(Elliptic Curve Diffie-Hellman), implemented purely in Python, released under
|
|
the MIT license. With this library, you can quickly create key pairs (signing
|
|
key and verifying key), sign messages, and verify the signatures. You can also
|
|
agree on a shared secret key based on exchanged public keys. The keys and
|
|
signatures are very short, making them easy to handle and incorporate into other
|
|
protocols.
|
|
|
|
This library provides key generation, signing, verifying, and shared secret
|
|
derivation for five popular NIST "Suite B" GF(p) (prime field) curves, with key
|
|
lengths of 192, 224, 256, 384, and 521 bits. The "short names" for these curves,
|
|
as known by the OpenSSL tool (openssl ecparam -list_curves), are: prime192v1,
|
|
secp224r1, prime256v1, secp384r1, and secp521r1. It includes the 256-bit curve
|
|
secp256k1 used by Bitcoin. There is also support for the regular (non-twisted)
|
|
variants of Brainpool curves from 160 to 512 bits. The "short names" of those
|
|
curves are: brainpoolP160r1, brainpoolP192r1, brainpoolP224r1, brainpoolP256r1,
|
|
brainpoolP320r1, brainpoolP384r1, brainpoolP512r1. Few of the small curves from
|
|
SEC standard are also included (mainly to speed-up testing of the library),
|
|
those are: secp112r1, secp112r2, secp128r1, and secp160r1. No other curves are
|
|
included, but it is not too hard to add support for more curves over prime
|
|
fields.
