What is MD5?
MD5 (Message Digest Algorithm 5) is a widely used hash function producing a 128-bit (16-byte) hash value, typically rendered as a 32-digit hexadecimal number. It is commonly used for file integrity verification and data deduplication.
MD5 vs SHA-1 vs SHA-256
- MD5: 128-bit, fastest, but not recommended for security
- SHA-1: 160-bit, more secure than MD5 but also considered deprecated
- SHA-256: 256-bit, currently the recommended secure hash algorithm
