TechCrunch on Facebook supporting PGP for sending encrypted notification emails and also allowing users to post their public keys on their profile:
Facebook uses the well-established PGP scheme (the GNU Privacy Guard implementation of OpenPGP, to be precise) to encrypt messages and tools like Mailvelope for Gmail users now make it a bit more straightforward to generate and manage keys in order to read and write encrypted emails. It’s still by no means a completely trivial procedure, and you still need to have a basic understanding of what you are doing.
Facebook acknowledges as much and points potential users to the Electronic Frontier Foundation’s introduction to PGP. Sadly, Facebook made no attempt at hiding the complexity of using PGP, so it’s unlikely that many regular users will actually sign up for it.
The company says
it’s rolling out this new feature slowlythe feature is now available globally. If you want to see if it’s available for your account, head to your Facebook settings, look for the contact info section and you should see the option to add a PGP public key.
It is great to see a large web-based company like Facebook support encryption, but unfortunate they did not dumb this down enough for the lowest common denominator. It would have been nice to see Facebook offer a tutorial of some sort, and help instruct the average user on how to use PGP to secure their communications.
At the very least, this is a nice start.
