Our public PGP-key for signatures

Don't be confusing it with the one used for sending encrypted emails posted in the relevant section above. Each maintainer has their own key derived from this one, also posted below, their git-commits are to be signed with their own keys. You'll only have to fetch and import the primary key.

Follow the instructions on how to fetch this key from multiple sources and compare the key you fetched is the same. Only after making sure each key fetched from an alternative source is identical to each other, you can safely import it, knowing it was not compromised.

The instructions on how to verify various releases, files and pages of this website, even, are posted below.

Key fingerprint: 79A0BC4C74F1B4735DE1FFD6BBE27E7A48235ED1
Details: rsa4096, expires on: 2027-08-12

STEP 0: install GnuPG (if it's not installed already)
On most Linux systems it is installed by default. If not, or if you're using a system where it isn't installed, refer to the GnuPG official website's download page
STEP 1: How fetch the key from multiple sources
  1. Fetch the same key from multiple sources:
    gpg --keyserver hkp://keyserver.ubuntu.com --receive-keys '0B2A280B11A14B1F244797892644A91766CFCF9F'
    gpg --keyserver hkp://keyserver.ubuntu.com --receive-keys '0B2A280B11A14B1F244797892644A91766CFCF9F'
    curl "https://pfc.tools/pgp-keys/PFC-tools_signature-1_0B2A280B.pub.asc" \ -o PFC_tools_main_key_0B2A280B.ascgpg --import PFC_tools_main_key_0B2A280B.asc

Each time (except for the first one) the output should say "unchanged: 1" which would mean the key is the exact same you've already imported before.


The key above will be used to sign official releases, official PFC-compatible images (both for containers and VMs) and other files such as recipes that may be released by the PFC-team itself.

STEP 2: import our PGP key

Assuming the downloaded file and signature are in the same directory, cd into it and type the following command: pgp --import PFC_tools_main_key_0B2A280B.asc

STEP: verify PGP-signatures of the downloaded files

Every file released by the PFC toolset team, be it an archive, an ISO image or a recipe script shall be accompanied by .asc signature file of the identical name. Once we complete Set 1 of our features, verification will become extremely easy. For now, however, we'll have to provide these instructions for you. They shall work the same on all open platforms, provided you have GnuPG installed and a gpg command is available in your terminal.

To verify a downloaded file was signed by the "PFC tools" PGP public key, type the following command in your terminal (assuming you downloaded both files into the same directory):

gpg --verify pfc_tools_v0.0.0.tar.gz.asc

The filename used above is an example, it may differ, of course.

After completing Set 1 of PFC features, the public key, signature fetching and verification processes will be automated. Until then, please follow these instructions, so you wouldn't have to do it manually.
