RSA ****** Encrypt your texts with the left button, decrypt the file again (also on another computer) by clicking on the right button. The project will guide you. Have fun an try out what you can do with it.
RSA is a well-known encrypting method. By changing the text to ASCII-Code, I can easily try this out. However, my method isn't safe because the prime numbers I used in the project are to little - they should be bigger than a 1 with 200 zeros, and that wouldn't work, because that would took scratch thousands of years.. I hope you enjoy:)
