Cryptnotes - Version 2.1 Encrypts and decrypts messages without the need for cumbersome cut and paste. The initial password is "sample" without the quotes. File size is small at 120 kb installed which makes it ideal for sending to friends. Messages can be anywhere on your drives (even floppies) which means it can even be an email attachment sent to you. Just click it to open and enter the correct password to decrypt.
