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).

The shared object libmd.so.1 provides the public interfaces defined below. See Intro(3) for additional information on shared object interfaces.

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.
