WebOct 1, 2024 · HMAC is not an encryption algorithm. It uses a hash algorithm like SHA256 to create a Message Authentication Code (a MAC) that can be used to verify the integrity of the message, and because it's based on a shared secret key, verify the identity of the sender. There's no encryption in there at all Webimport javax.crypto.Mac; import javax.crypto.spec.SecretKeySpec; import java.security.InvalidKeyException; import java.security.NoSuchAlgorithmException;
