Here's a quick example on how to use sodium_crypto_auth(); where you have a message that you want to sign, so anyone who can access the *shared* key can confirm that the message hasn't been tampered with. This is similar to sodium_crypto_sign_detached(), but both signer and verifier have access to the same key. <?php $key = sodium_crypto_auth_keygen(); //-------------------------------------------------- // Person 1, signing $message = 'Hello'; $signature = sodium_crypto_auth($message, $key); //-------------------------------------------------- // Person 2, verifying $message_valid = sodium_crypto_auth_verify($signature, $message, $key); if (!$message_valid) { exit('Message has been changed.'); } ?>
