Maskbook is a cryptography tool that allows you to post encrypted posts and send encrypted messages to friends on social networks you already use. It keeps your privacy from being stolen and abused by the platforms.

You can now enjoy the full privacy across major social network platforms through end-to-end encryption. To make this happen, all you need to do is to go through the setup guide (in which you will create a keypair, FYI if you wonder how) and you just use it right away!

Maskbook is a free software licensed with AGPL 3.0 and we are willing to take any code and safety audit from anyone. We do not and will never store any personal data of yours!
