WebMD2, MD4, and MD5 are cryptographic hash functions with a 128 bit output. MD2 (), MD4 (), and MD5 () compute the MD2, MD4, and MD5 message digest of the n bytes at d and place it in md (which must have space for MD2_DIGEST_LENGTH == MD4_DIGEST_LENGTH == MD5_DIGEST_LENGTH == 16 bytes of output). If md is NULL, the digest is placed in … WebMD5 is a cryptographic hash function standardized in RFC 1321 and designed by Ronald Rivest.
