Cryptor.dll Binary encryption/decryption Tutorial

[therealmethuselah]

I made a small example (since roach took down his link) using it with binary encryption/decryption. You set your own key in the cryptorInitialize(); script.

I encrypted a .gif file into graphic.enc using the cryptorEncryptFile(); script, then deleted the .gif so I just had the .enc file. Then I can load this encrypted graphic (which I extract to the temp_directory so it is deleted when the game is ended) into the game and display it in the middle of the screen.



I suggest atleast a 12 character key.

In the Creation code of room0, I have this code:

{
// Initialize the Cryptor.dll
cryptorInitialize();
// Create the avatar in the center of the screen
instance_create(128, 112, objCryptor);
}

For additional security, give the encrypted file an extension of a common filetype different from the original. Eg: encrypt "link.png" into "link.zip". Encrypt "myImage.bmp" into "myZip.zip" or something along those lines. Don't give away the original filetype and the fact that it's encrypted anywhere in the filename, and a cracker (one who cracks encryptions) won't have a clue - they'll just think it's a corrupted zip or something.

If you check out my game 'Plains of Chaos' (look at my signature) I actually have my own file types encrypted and 7-zipped. w00t!
