<?php //-------------------------------------------------- // 1. Create a key encryption::key_symmetric_create('my-key'); //-------------------------------------------------- // 2. Encrypt $message = 'Hello'; $encrypted_1 = encryption::encode($message, 'my-key'); //-------------------------------------------------- // 3. Create new key, re-encrypt, delete old key $new_key_id = encryption::key_symmetric_create('my-key'); $decrypted_1 = encryption::decode($encrypted_1, 'my-key'); $encrypted_2 = encryption::encode($decrypted_1, 'my-key'); encryption::key_cleanup('my-key', [$new_key_id]); //-------------------------------------------------- // 4. Decrypt with new key $decrypted_2 = encryption::decode($encrypted_2, 'my-key'); //-------------------------------------------------- // Results echo debug_dump([ $encrypted_1, $decrypted_1, $new_key_id, $encrypted_2, $decrypted_2, ]); ?>
