JavaScript Encryption and Decryption 2.0

The new version of JavaScript Encryption and Decryption is out!

Try it:
Show encrypted text  (the decryption key is: password)

The new encryption code is a lot faster than the old version and the webpage decryption code now uses a fancy dialog box to ask you for the key. The entire process has been greatly simplified and the encryption page will automatically generate code that you can copy and paste into your website.

Note: the new version is not backwards compatible with the old version

    Hi Vincent,

    Excellent work with the encryption/decryption code.

    My question is – can I read the key from the web.config file instead of the default pop up dialog? If so, please demonstrate how.

    Many thanks.

    As the code stands, you must enter the key either using the pop-up dialog or the JavaScript dialog prompt.

    Is there anyway to hide/disable the tooltip/popup message box that currently displays the encrypted text string from the DIV section without forcing the viewer to disable in their browser? I’ve been fiddling around with it but seem to be getting nowhere with it.

    I’ve managed to stop it from displaying when the mouse is over the actual link by overriding the TITLE from the DIV with another blank entry at the HREF (i.e. link). However, the tooltip still appears when the mouse becomes the caret when near the link text. I’m thinking a onMouseOver event but dunno what to call after that.

    Thnks and rgrds

    As of now, there is no way to stop the popup. It is browser dependent. I’ll look into ways that I can fix this.

    I would like to use yiour code to stuff encrypted data into a database as it is created and then pull it out to display from the database when needed. Is the source code available to encrypt and decrypt to include on my website?

    Just take a look at the JavaScript files or use OpenSSL.

    The password box won’t pop up when I try it either. I’m just a beginner with html code, but I think I’m following the instructions carefully. Does it not work with all blogger layouts?

    This is COMPLETELY brilliant! I am SO impressed! I tried a while back to use this service but I was foxed by the HTML, but NOW I have been a bit braver and it works!

    I’d actually like to format the text so that it doesn’t just run in a long line when revealed. I am trying to put my CV/resume online so it does need to look professional.

    If formatting is too tricky, a pdf, or an image of a pdf (like the icon image you’ve used) would work. But I don’t know where to host the image. Shall I just import it to blogger as usual?

    Thanks for all your hard work.

    When you encode the text, don’t just encode the plain text, encode the html code and then it should do what you want.
