Can 开发者_StackOverflow社区you point me to an opensource implementation of an encrypted qr code similar to what quickmark is doing? check this out:

http://www.quickmark.com.tw/En/diy/?qrEncrypt

If possible, an implementation that works on both mobile and pc applications.

Here is a quick explanation on how QuickMark works http://uvsar.blogspot.com/2009/05/secure-qr-and-qm-codes.html

They appear to be simply encoding the encrypted data as a URL with the prefix 'pe:', followed by the raw encrypted data. There isn't a standard for this, so you can do it however you want, really. Are you trying to make something compatible with their system? If not, what are your requirements? I'm finding it hard to understand why you'd want an encrypted QR code.

It seems simpler to create a password-protected web page and just encode its URL. Then it works on any reader (though you have to host a webpage somewhere.)

This C# Open Source QR code library can be usefull. It, works for mobile applications too.
