libmd(3LIB) Interface Libraries libmd(3LIB)NAMElibmd - 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.

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 SHA256, SHA386 or SHA512-is
highly recommended when compatibility with data formats and on wire
protocols is permitted.
