Here's a quick example on how to use sodium_crypto_sign_detached(); where you have a message that you want to sign, so anyone with the public key can confirm that the message hasn't been tampered with. This is similar to sodium_crypto_sign(), but the returned string does not contain the original message, it is just a signature. <?php // $sign_seed = random_bytes(SODIUM_CRYPTO_SIGN_SEEDBYTES); // $sign_pair = sodium_crypto_sign_seed_keypair($sign_seed); $sign_pair = sodium_crypto_sign_keypair(); $sign_secret = sodium_crypto_sign_secretkey($sign_pair); $sign_public = sodium_crypto_sign_publickey($sign_pair); //-------------------------------------------------- // Person 1, signing $message = 'Hello'; $signature = sodium_crypto_sign_detached($message, $sign_secret); //-------------------------------------------------- // Person 2, verifying $message_valid = sodium_crypto_sign_verify_detached($signature, $message, $sign_public); if (!$message_valid) { exit('Message has been changed.'); } ?>
