sodium_crypto_auth

    (PHP 7 >= 7.2.0, PHP 8)

    sodium_crypto_auth — Compute a tag for the message

    说明

    sodium_crypto_auth(string $message, #[\SensitiveParameter] string $key): string

    Symmetric message authentication via sodium_crypto_auth() provides integrity, but not confidentiality.

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

    参数

    message

    The message you intend to authenticate

    key

    Authentication key

    返回值

    Authentication tag
