Facebook Adds PGP Encryption to Keep Emails Safe From Hackers

Facebook is adding the ability to upload an encryption key to your profile to prevent hackers from snooping on your notification emails. The ability to add OpenPGP public keys to profiles is rolling out on Monday.
Each user has a public key and a private key; both are similar to what you might see generated from password platforms such as 1Password or LastPass. But by giving users the option to add a PGP key to their pages, it gives that standard much more visibility and could go a long way toward making stronger security a priority for more people on the web.
