stegamsg's Issues

Make this actually secure

TODO:

• Rewrite back-end in Go
  • RESTful backend serving JSON objects
• encrypt and decrypt in client-side only
  • New data-flow for posts:
    1. Request image from server
    2. Encrypt message in image
    3. Send image back to server

Sanitize input

Things break all over the place if the message can't fit in the image.

FIX: fetch image from server, compute max characters that will fit in the image, do not allow input that will exceed that value

... consider huffman compression before encryption; this will allow one to write longer messages at the expense of slower client-side code.

Provide support for group conversations

Hello!
Currently multiple users can join a group but there is no way to tell which user sent a message, which could be very confusing if attempting to hold a group conversation. Could this be improved by having a specific message box colour assigned to each connected user, or have the message display a username the user chooses like how IRC clients do it?
