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, 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
