NAME
       libmd - Message Digest library

SYNOPSIS
       cc [ flag... ] file... -lmd [ library... ]
       #include <md4.h>
       #include <md5.h>
       #include <sha1.h>
       #include <sha2.h>

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  inter-
       faces.

       MD4Final 		     MD4Init
       MD4Update		     md5_calc
       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.
