Defined by RFC 1321 (1992), MD5 outputs a 128-bit hash value. In 2004, Wang Xiaoyun's team demonstrated MD5 collision attacks; by 2008, collisions could be generated in under 1 second. Therefore MD5 is not recommended for security use (password storage, digital signatures, certificate verification). It remains acceptable for: file dedup (non-security), checksums for download integrity, DB sharding, cache key generation in non-security contexts. For security, use SHA-256 or SHA-3.
