Revision	Date	Author	Comments
1.5	05-Oct-2017	roy	Cast away some compile warnings.
1.4	10-Jan-2017	christos	add missing cast.
1.3	01-Jul-2016	christos	branches: 1.3.2; new hmac function.
1.2	27-Oct-2006	drochner	As discussed back in June, remove hmac_sha1 and hmac_md5 from libc, to reduce bloat and namespace trouble. (both were never public; hmac_sha1 is moved to libcrypt now because it is used locally there)
1.1	02-Jul-2004	sjg	Add support for SHA1 hashed passwords. The algorithm used is essentially PBKDF1 from RFC 2898 but using hmac_sha1 rather than SHA1 directly (suggested by smb@research.att.com). * The format of the encrypted password is: * $<tag>$<iterations>$<salt>$<digest> * * where: * <tag> is "sha1" * <iterations> is an unsigned int identifying how many rounds * have been applied to <digest>. The number * should vary slightly for each password to make * it harder to generate a dictionary of * pre-computed hashes. See crypt_sha1_iterations. * <salt> up to 64 bytes of random data, 8 bytes is * currently considered more than enough. * <digest> the hashed password. hmac.c implementes HMAC as defined in RFC 2104 and includes a unit test for both hmac_sha1 and hmac_sha1 using a selection of the Known Answer Tests from RFC 2202. It is worth noting that to be FIPS compliant the hmac key (password) should be 10-20 chars.
1.3.2.1	20-Mar-2017	pgoyette	Sync with HEAD
