I created my own encrypt / decrypt script and I can encrypt any kind of strings. I just need to know how can I use my script to encrypt a file like an image or a text file?
My script is working in PHP, C++ and VB.
Can be very basic:
Encode file to base64, encrypt it, sent it to target, decrypt with your script to base64 and decode the base64 to a image file. But this has nothing to do with informaction security. Move to StackOverflow is better.
