Generate Hash-based Message Authentication Codes (HMAC) using various cryptographic hash functions. HMAC provides a secure way to verify both the data integrity and authenticity of a message.
SHA-256 is a cryptographic hash function that produces a 256-bit (32-byte) hash value. It's commonly used in security protocols and applications.
HMAC (Hash-based Message Authentication Code) is a specific type of message authentication code (MAC) involving a cryptographic hash function and a secret cryptographic key. It provides both data integrity and authentication.
