About Hash Functions

MD5: 128-bit digest. Fast but cryptographically broken. Not suitable for security.
SHA-1: 160-bit digest. Deprecated due to collision attacks.
SHA-256: 256-bit digest. Part of SHA-2 family. Currently secure and widely used.
SHA-512: 512-bit digest. Part of SHA-2 family. Provides longer hash output.
