HMAC
(Hash-based Message Authentication Code)
Hash-based Message Authentication Code (HMAC) is a cryptographic technique used to verify the integrity and authenticity of a message. HMAC combines a cryptographic hash function (like SHA-256) with a secret key to produce a unique code that can be verified by the recipient.
HMAC is widely used in secure communication protocols like TLS and IPSec to ensure that messages have not been tampered with during transmission. It is also used in APIs and digital signatures to provide data integrity and authentication. HMAC is a fundamental tool in modern cryptography, ensuring secure and reliable communication.
