Finished Encryption engine (applying a XOR mask, this way decryption is using the same function, like a “toggle”), trauncated/repeated the key where plaintext was not the same size, and finsished handshake between a client running the script and server (will make them both the same next, so both are listening and either can send the first request). All that is left after that is a GUI
Image shows the word “hello”, then the word being encrypted by a random priv key, then the result after reusing the encryption function (which returns the original message here)
