PDF.js v0.7.138 (build: 06af8a2) Message: unsupported encryption algorithm Adobe Acrobat XI (11.0.1) opens both files properly. Security algorithm seems to be 256-bit AES. gigaherz commented Feb 1, 2013 Apparently PDF.js currently only support ARC4 and 128-bit AES. A quick googling brought me to http://code.google.com/p/crypto-js/, which seems to be an actively maintained, BSD-licensed javascript library. This means implementing support for endpoint encryption error 256-bit AES may be relatively simple, assuming the license is compatible and there isn't some other reason not to use it. I don't know how much this encryption format is used, but if it hasn't been implemented yet then chances are it's not used much, which means the development team will have other more important issues to work on. So it may be up to you to implement the feature yourself, if you have a strong enough need for it. anukin commented Feb 13, 2014 can any body mentor me on how to get started on this ?? all help will be appreciated timvandermeij commented Feb 13, 2014 @anukin The best thing to do is get in touch with a developer via IRC. Use irc.mozilla.org and channel #pdfjs and we will try to help you get started. anukin commented Mar 16, 2014 thank you i have already done that thanks anyway ! … On Fri, Feb 14, 2014 at 2:26 AM, Tim van der Meij ***@***.***>wrote: @anukin
