Descrição

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.)

Parâmetros

mac

message

Message

key

Authentication key

Valor Retornado

Retorna true em caso de sucesso ou false em caso de falha.
