Compute a tag for the message
Description
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.)
Parameters
messageThe message you intend to authenticate
keyAuthentication key
Return Values
Authentication tag
