Slock is a browser extension to effortlessly provide E2E encryption on Facebook Messenger.

Tell me more

Slock uses public key cryptography to automatically encrypt your chats on Facebook Messenger. Instead of using a random server to get your friends' public keys, it uses Facebook's Graph API! If a Facebook friend of yours installs the extension and uploads their own public key to their Facebook profile all of your chats with that particular friend will be automatically encrypted!

No private keys or passwords are ever sent over the network! All encryption and decryption is done client side!


When completed, Slock will be available in the Chrome Web Store. Until then, you can test out the dev builds by:

What's next?

Slock doesn't want to just stop at just Facebook Messenger. We'd like to target other messaging platforms as well!
