People may also choose to share OpenPGP keys from their profile, with or without enabling encrypted notifications.
for avoid countless spams or alerts, many of the users turn off their email notifications from Facebook.
One can upload their public key by going to profiles contact info configs.
Your public key can be used to encrypt notifications and other alerts sent to you from Facebook.
On receipt of the messages, one can decrypt them using their corresponding private key.
Nobody except the user should have a copy of the private key.
One cannot upload a private key instead of a public key, as it is blocked by Facebook.
However, there is a flipside of enabling encrypted messages from Facebook.
Repeated warnings regarding the same is provided by Facebook.
A test was conducted byThe Registerto check out the new service.
Decrypting the message from Facebook was as simple as gpg output facebook.txt decrypt encrypted.asc.
The file encrypted.asc was attached to the received email as reported by The Register.
Operational keys will be rotated occasionally for security purposes says the company.
Choosing of GPG is no accident for Facebook.
According to Facebook, its implementation will support the ElGamal or RSA algorithms.
It is also researching GPGs newer elliptic curve algorithms.
The move by Facebooks to introduce encryption is likely to catch more peoples attention.
Further, also the addition of GPG might make a few users think more seriously about security.
