Crypt - Version 1.02 File encryption and decryption utility for W95 and NT. If you have ever felt the need to leave a file on a computer (yours or not), modified in some way so that nobody else can read and understand it, this program is a must for you. It uses a cyclic algorithm (the same routine is used to crypt and decrypt) that does not modify the size of the file, and the interface is extremely easy to use and intuitive.
