LHN's CryptSym (Free) v1.10 is a free Windows application that reads a list of numbers called "KEY" (from 0 to 99) and provides a SYMMETRIC ENCRYPTION of the text. In reverse, it does a process of decryption over an encrypted text. If the key is wrong, the decryption process will fail and the original message cannot be discovered. Encryption and Decryption are based on the text they receive in the corresponding area. Use the buttons according to the process you want to use. Providing the Key to another person enables a symmetric exchange of encrypted contents.
