Hi, In my previous mail, I was planning to add steganography libraries to the extension. But with the meeting with mentor, we planned to complete the code with proper documentation and to add public key cryptography features. But in my plan, I was able to complete all the UIs and back end framework for all the parts of the extension other than few updates remaining in options page. In cumming weeks, I will be working on completion of code and will add public key cryptography libraries which need some modification from existing libraries. -- Hareesan
