MD5: 128-bit (32 chars), fast but vulnerable to security, checksum purpose
SHA-1: 160-bit (40 chars), vulnerabilities found, legacy system compatibility
SHA-256: 256-bit (64 chars), currently recommended security standard
SHA-512: 512-bit (128 chars), highest security level, for large data
CRC32: 32-bit (8 chars), error detection only, not a security hash
