KeyScrambler is used for anti-keylogging i.e providing protection from password stealing.
KeyScrambler encrypts your keystrokes at the keyboard driver level in the kernel, as they enter the computer. It then decrypts the keystrokes at the destination application, so you see exactly the keys youve typed. Whatever keylogger might be waiting along the path has only the encrypted keys — "scrambled" and indecipherable — to record.
The freeware personal edition provides protection for Internet Explorer, Firefox, and Flock web browsers.
