sodium_crypto_auth - Compute a tag for the message
Manual
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
- message
-
The message you intend to authenticate
- key
-
Authentication key
Return Values
Authentication tag
