About HMAC
HMAC (Hash-based Message Authentication Code) is a cryptographic authentication mechanism used to verify the integrity and authenticity of messages. It creates a unique digest of the message using a hash function and a secret key.
Use Cases
- API security
- Message verification
- Digital signatures
- Data integrity control
- Session tokens
HMAC vs Hash
- HMAC depends on secret key
- More secure against attacks
- Verifies data sources
- Used between agreed parties
