NAME
     libmd - Message Digest library

SYNOPSIS
     cc [ flag... ] file... -lmd [ library... ]
     #include

DESCRIPTION
     Functions in this library provide hashing routines  for  MD4
     (RFC1320),  MD5 (RFC1321), SHA1 (RFC3174), SHA256 (FIPS 180-
     2), SHA384 (FIPS 180-2), SHA512 (FIPS 180-2).

INTERFACES
     The shared object libmd.so.1 provides the public  interfaces
     defined  below.  See  Intro(3) for additional information on
     shared object interfaces.



     MD4Final                      MD4Init
     MD4Update                     md5calc
     MD5Final                      MD5Init
     MD5Update                     SHA1Final
     SHA1Init                      SHA1Update
     SHA2Final                     SHA2Init
     SHA2Update


SECURITY
     The MD4 and MD5 algorithms are currently considered weak for
     cryptographic  use.  The  algorithms should be used only for
     compatibility with legacy systems or protocols.


     The SHA1 algorithm is also believed to have some weaknesses.
     Migration  to  one  of the SHA2 algorithms-including SHA256,
     SHA386 or SHA512-is highly  recommended  when  compatibility
     with data formats and on wire protocols is permitted.

FILES
