sodium_crypto_auth_verify — Verifies that the tag is valid for the message

Beschreibung

sodium_crypto_auth_verify(string $mac, string $message, #[\SensitiveParameter] string $key): bool

Verify the authentication tag is valid for a given message and key.

Unlike with digital signatures (e.g. sodium_crypto_sign_verify_detached()), any party capable of verifying a message is also capable of authenticating their own messages. (Hence, symmetric authentication.)
