KeyScrambler is a security application that encrypts keystrokes at the keyboard driver level within the operating system kernel. The encryption process runs before the keystrokes reach any application. The technology prevents both software and hardware keyloggers from capturing readable information. KeyScrambler decrypts the keystrokes only in the designated target application, displaying the original text to the user. The free Personal edition protects web browsing in 33 browsers, including Chrome, Firefox, and Edge.
