Crack-Proof Encryption v1.0

To use, send ENCRYPT.8XG to your calculator. To encrypt, run prgmENCRYPT. You will be prompted for a 4-digit passcode. The passcode must be numerical (0-9) and exactly 4-digits in length. You will then enter the text you wish to encrypt. The text will be encrypted, and you will be prompted for a picture to save to. Enter a number 0-9.

To decrypt, run prgmDECRYPT. You will need to enter the picture number, and then the 4-digit passcode. The text will then be decrypted. I know it's very slow, but that's the price you pay for good encryption.


Personal Guarantee: I guarantee that the encryption method used in these programs is unbeatable.

Disclaimer: If you or your friends are really bored, and have access to a supercomputer, and a LOT of computer time, you might be able to crack the encryption (or if you look at the source code). However, once the programs are on the calculator, they are completely foolproof from teachers and other students.
