NAME

libmd - Message Digest library

LIBRARY

Message Digest Library (libmd, -lmd)

SYNOPSIS

#include <md4.h>
#include <md5.h>
#include <sha1.h>
#include <sha2.h>
#include <sys/edonr.h>
#include <sys/skein.h>

DESCRIPTION

This library provides hashing routines for the following suites of hash
functions:
+o MD4 (RFC1320)
+o MD5 (RFC1321)
+o SHA1 (RFC3174)
+o SHA256 (FIPS 180-2)
+o SHA384 (FIPS 180-2)
+o SHA512 (FIPS 180-2)
+o Edon-R (Cryptographic hash function Edon-R.)
+o Skein 256, 512, and 1024 (The Skein Hash Function Family.)

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 data formats and on wire protocols support
the use of SHA2.
