Facebook will send encrypted emails is users add PGP key to profile
Some Facebook users should soon be able to receive encrypted emails from the social networking site if they add PGP public keys to their profiles.
Facebook called the PGP feature “experimental” and said it is slowly rolling it out, although a timeline wasn’t provided. The PGP key details will be added to the “contact and basic info section” of a person’s profile under “contact information.”
Facebook sends messages to private email accounts to inform users when they have a private message or friend request, for example. It currently uses TLS to establish secure connections to a person’s email provider, but this won’t keep the details of an email private from prying eyes.
