NAME
       libmd - Message Digest library

SYNOPSIS
       cc [ flag... ] file... -lmd [ library... ]
       #include <md4.h>
       #include <md5.h>
       #include <sha1.h>
       #include <sha2.h>
       #include <sha3.h>

DESCRIPTION
       Functions  in  this library provide hashing routines for MD4 (RFC1320),
       MD5 (RFC1321),  SHA1  (RFC3174),  SHA224  (FIPS  180-2),  SHA256  (FIPS
       180-2),  SHA384  (FIPS  180-2), SHA512 (FIPS 180-2), and SHA512/t (FIPS
       180-4) for t = 224 and 256 and the SHA3 (FIPS 202) family of hash func‐
       tions (224, 256, 384 and 512-bit versions).

INTERFACES
       The shared object libmd.so.1 provides the public interfaces defined be‐
       low. See intro(3) for additional information on  shared  object  inter‐
       faces.

       The shared object libmd.so.1 also provides these public interfaces that
       implement  variants  of  SHA-2  and  may  perform faster on some 64-bit
       processors:

       tab(); lw(2.75i) lw(2.75i) SHA512_t_FinalSHA512_t_Init SHA512_t_Update



       The digest values produced by the SHA512/224 and  SHA512/256  functions
       are  not  the same as those digest values produced by the corresponding
       SHA2 functions.

SECURITY
       The MD4 and MD5 algorithms are currently considered  weak  for  crypto‐
       graphic  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  SHA224, SHA256, SHA386 or
       SHA512— or a member of the SHA3 family is highly recommended when  com‐
       patibility with data formats and on wire protocols permit doing so.
