What is HMAC-SHA256?
HMAC-SHA256 is an industry-standard message authentication code that uses the SHA-256 hash function. It is widely used in APIs (like AWS and JWT) to verify that data hasn't been tampered with.
Security Status
HMAC-SHA256 is currently considered highly secure and is recommended for almost all new authentication and integrity verification needs. It offers a 128-bit security level against most attacks.
