This is directed to the user that claims to have expanded his 18 digit CC number to a 12kb document.
The fact that you encrypts 18 bytes to 12000 bytes means that you have a whole lot of redundancy in
your ciphertext. The more redundancy you have the more information your ciphertext tells about the
choosen key (or in other words - the unicity distance is extremely low for your encryption system)
