- <h1>Dojo SQL Cryptography</h1>
-
- <h2>Instructions</h2>
-
- <p>This demo shows Dojo Offline's SQL encryption technologies. 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. To learn how you can use this feature
- <a href="http://docs.google.com/View?docid=dhkhksk4_8gdp9gr#crypto" target="_blank">see here</a>.</p>
