In the table below, we have a + sample SQL table that has three columns of data: a last name, a first name, and + a social security number. We don't want to store the social security numbers + in the clear, just in case they are downloaded for offline use to a laptop and the + laptop is stolen.</p> + + <p>To use this demo, enter a password and press the ENCRYPT button to see the Social Security column encrypt. Enter + the same password and press DECRYPT to see it decrypt. If you enter an incorrect password and + press DECRYPT, the Social Security column will remain encrypted and only show gibberish.</p> + + <p>Under the covers we use 256-bit AES encryption and your password to derive the crypto key; we use + a facility in Google Gears to do the cryptography in such a way that the browser does not lock up + during processing. Dojo Offline ties this cryptography into Dojo SQL, providing convenient ENCRYPT() + and DECRYPT() SQL keywords you can use to easily have this functionality in your + own offline applications.
