This is Eric Young's SSL and Crypto library. It includes

libssl.a:
	An implementation of Netscapes SSL v 2 protocol.  This library
	implements the SSL protocol.

libcrypto.a:
	General encryption and X509 stuff needed by SSL but not
	actually logically part of it.  It includes routines for the following:
	RC4 encryption,
	IDEA encryption - 4 different modes, ecb, cbc, cfb and ofb.
	MD5 and MD2 message digest algorithms,
	SHA (SHA-0) and SHA-1 message digest algorithms,
	RSA encryption/decryption/key generation.  There is no limit
		on the number of bits.
	Diffie-Hellman key-exchange/key generation.  There is no limit
		on the number of bits.
	X509 encoding/decoding into/from binary ASN1 and a
		PEM based ascii-binary encoding which supports encryption with
		a private key.
        (The DES routines, while a part if this source distribution
        are not included in the compiled package, as they are part
        of the base FreeBSD secure/ distribution)

Programs in this package include
	enc	- a general encryption program that can encrypt/decrypt using
		one of 17 different cipher/mode combinations.  The
		input/output can also be converted to/from base64
		ascii encoding.
	dgst	- a generate message digesting program that will generate
		message digests for any of md2, md5, sha (sha-0) or sha-1.
	asn1parse - parse and display the structure of an asn1 encoded
		binary file.
	rsa	- Manipulate RSA private keys.
	dh	- Manipulate Diffie-Hellman parameter files.
	crl	- Manipulate certificate revocation lists.
	x509	- Manipulate x509 certificates, self-sign certificates.
	req	- Manipulate PKCS#10 certificate requests and also
		  generate certificate requests.
	genrsa  - Generates an arbitrary sized RSA private key.
	gendh	- Generates a set of Diffie-Hellman parameters, the prime
		will be a strong prime.
	ca	- Create certificates from PKCS#10 certificate requests.
		This program also maintains a database of certificates
		issued.
	verify	- Check x509 certificate signatures.
	speed	- Benchmark SSLeay's ciphers.
	s_server - A test SSL server.
	s_client - A test SSL client.
	s_time	 - Benchmark SSL performance of SSL server programs.
