Enigma Keyboard - a keyboard with the ability
to encrypt and decrypt text on the fly. The application uses the
RSA encryption algorithm which allows you to exchange keys over an
unsecured channel. The keyboard can be used in the usual typing
mode if necessary to encrypt the message at the end of the text you
just need to specify the name of the contact whose key will be
encrypted. The resulting encrypted text can be decrypted by placing
it in the clipboard.
