Ghostphrase is a symmetric cipher that can be used with most email clients
Ghostphrase is a symmetric cipher that can be used with most mail clients available.
It employs three passwords, and has a large internal key, generated with real 20-sided dice for true randomness.
There is an over 40-fold excess random changes produced at each encryption. A mouse-clicked screen keyboard makes it resistant to most keylogging spyware.
The input clear text is not visible on the screen. Max message size: 2000 characters. Users can check current size while writing. The total key size is 48352 bits. Ghostphrase is free to download as a .exe file.
There are two registration/paying options, Silver and Gold. Silver users get to download versions with changed internal keys from a hidden weblink at regular intervals. Gold subscribers get a CD with a unique internal key, created on a stand-alone computer, as often they want.
All users are free to copy the software. A help text file and a binary usage tracking file are produced in the same folder as the software. Some other temporary files are produced, but not seen normally.
No cookies or similar are planted. The program does not access email or internet by itself. Crypt files are deleted if older that two days. Clear text files are deleted on next program run.
Files are deleted automatically by the c++ remove command, but may still be retrievable from the hard drive. Users can choose clear text output as screen only, or screen plus text file.
For ultimate security it is recommended user encrypt and decrypt on a stand-alone computer, and send/recieve using another computer.
