Manual
sodium_crypto_auth_verify(
string$mac,
string$message,
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.)
Parameters

Authentication key
