Recovering Blurred Text Using Photoshop and JavaScript

    drawing a big black rectangle is 10x faster and there is no way you can de-obfuscate that

    Just make sure you're not saving in a file format that has a preview, where the preview doesn't have the obfuscation updated. :)

    You're not missing anything.
    This guy tried to read some blurred text on his friend's site, so he decided to mess around in photoshop.

    He got over zealous and did some javascript stuff in photoshop, based on blurring known text and attempting to reblur and match that text 1 letter at a time.

    He was then disappointed that he couldn't use the thing to unblur assumed text of unknown font, font settings, color, language, character set, and blurring algorithm after unknown layers of image alteration after the text was rendered, and after unknown compression.
