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
       below. 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  pro‐
       cessors:


       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.
