Algorithm
MD5 (Message-Digest Algorithm 5) is a cryptographic hash function designed by Ronald Rivest in 1991 as a successor to MD4. It produces a 128-bit (16-byte) hash value, typically rendered as a 32-character hexadecimal string.
How It Works
The input is padded to a multiple of 512 bits, then processed in blocks through 4 rounds of 16 operations each, using bitwise functions, modular addition, and left rotation. The result is a fixed-size digest regardless of input length.
Common Uses
File integrity verification, checksum generation, deduplication, and non-security fingerprinting. MD5 is not recommended for cryptographic security — collision attacks have been demonstrated since 2004. Use SHA-256 or better for security-sensitive applications.
