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.)
