Hash Algorithms
Standard Hashes
- MD5: 128-bit, fast but not secure
- SHA1: 160-bit, deprecated for security
- SHA256: 256-bit, secure and recommended
- SHA512: 512-bit, highest security
HMAC
Hash-based Message Authentication Code (HMAC) uses a secret key to provide both data integrity and authentication. It prevents tampering and verifies the message source.
