- • Uses a secret key + hash function to verify message authenticity
- • HMAC-SHA256: 256-bit output, industry standard for API authentication
- • HMAC-SHA512: 512-bit output, highest security for sensitive operations
- • Key should be at least 32 bytes for optimal security
- • Common use cases: API request signing, webhook verification, JWT tokens
