Crypter was a renowned app that allowed you to encrypt Facebook chat messages. It was developed by Max Mitchell from Sussex University and was available as a browser extension on Chrome and Firefox. Crypter protected your chat through end-to-end AES encryption and offered heightened privacy for all Facebook users.
Unfortunately, Facebook has crippled this app and now has blocked users from using Crypter to encrypt their chat messages. The reason for this blocking has still not been disclosed by Facebook and the makers of Crypter are working hard to find a work around this problem.
Users of this app took to social media to express their frustration. Here is one user on Reddit showing his reaction towards Crypter being blocked by Facebook:
