How to use Facebook with gpg4o

Facebook very often has been criticized for careing less for the privacy of their members. At least at some single points of the Facebook User-Interface this has changed. Facebook members do have the opportunity to share their PGP public key with other people. In addition, one may receive messages from facebook encrypted with OpenPGP. As a vendor of GnuPG based software we are happy with this progress and want to show you how you can use Facebook with gpg4o. It will work similarly with other PGP or GPG software as well.

In Part 1 of this Howto we learn how we provide Facebook with our PGP Public Key.

Facebook option: Add a PGP public key

Facebook option: Add a PGP public key

Login to your Facebook account and navigate in “About” to “Contact and Basic info” amd then to “Add a public key”. There you will find a dialogue where you may insert your OpenPGP Public Key as Text. (Need to know how to get your Public Key as text? Click here!)

Dialog: Insert your PGP Public Key here

Choose the option „Use this public key to encrypt notification emailst that Facebook sends you?“ to receive mails from Facebook encrypted. Otherwise you only spread your PGP (GnuPG) Public Key via your Facebook account. When done your dialog should look like below:

You are done with Part 1. In the second part we will link the Facebook Public Key with gpg4o and possibly signed mails from Facebook. Please enter Outlook (with gpg4o installed) and change the ribbon to gpg4o and then click on key management. Use the keysearch function to look up the Facebook Public key (Short-ID DEE958CF) and compare the fingerprint of the key you obtained with the correct Public Key of Facebook.

While we cared about importing and validating the Facebook OpenPGP(GPG) Public Key you should have received an email from Facebook shown below:

email from facebook decrypted and signature verified

After doublechecking the signature you should follow the link in the email to verify that you successfully received and decrypted your first mail from facebook:

Facebook - successfully linked to gpg4o

Congratulation. You successfully bonded Facebook with your gpg4o installation and will receive status updates from Facebook encrypted.
