Get the Signing Key[edit]
This chapter is recommended for better security, but is not strictly required. (See Trust)
gpg --keyserver hkp://ipv4.pool.sks-keyservers.net:80 --recv-keys 916B8D99C38EAF5E8ADC7A2A8D66066A2EEACCDA
It isn't safe to only get the signing key from one source for the download you want to verify. For better security, learn more about the Whonix Signing Key.
Get the Source Code[edit]
Install git and curl.
sudo apt-get update && sudo apt-get install git curl
Get source code including git submodules.
git clone --jobs=4 --recursive https://github.com/Whonix/Whonix
Note: If using an older version of git (from Debian Jessie, Whonix 13, etc), remove --jobs=4.
Remember it is Whonix, not whonix! If prompted for a username for github, you have mistyped the web address.
Shift to the source folder.
cd Whonix
OpenPGP Verify the Source Code[edit]
This chapter is recommended for better security, but is not strictly required.[1]
Retrieve a list of available git tags.
cd ~/Whonix/ && git tag
Verify the chosen tag to build.
## ... Replace with tag you want to build. git verify-tag 14.0.1.3.8-stable
The output should look similar to this.
object 1844108109a5f2f8bddcf2257b9f3675be5cfb22 type commit tag 14.0.1.3.8 tagger Patrick Schleizer <adrelanos@riseup.net> 1392320095 +0000 . gpg: Signature made Thu 13 Feb 2014 07:34:55 PM UTC using RSA key ID 77BB3C48 gpg: Good signature from "Patrick Schleizer <adrelanos@riseup.net>" [ultimate]
 | Check the GPG signature timestamp makes sense. For example, if you previously saw a signature from 2018 and now see a signature from 2017, then this might be a targeted rollback (downgrade) or indefinite freeze attack. [2] |
The warning.
gpg: WARNING: This key is not certified with a trusted signature! gpg: There is no indication that the signature belongs to the owner.
Is explained on the Whonix Signing Key page and can be safely ignored.
By convention, git tags should point to signed git commits. [3] (forum discussion) It is advisable to verify the signature of the git commit as well (replace 14.0.1.3.8 with the actual git tag being verified).
git verify-commit 14.0.1.3.8-stable^{commit}
The output should look similar to this.
commit 5aa1c307c943be60e7d2bfa5727fa5ada3a79c4a
gpg: Signature made Sun 07 Dec 2014 01:22:22 AM UTC using RSA key ID 77BB3C48
gpg: Good signature from "Patrick Schleizer <adrelanos@riseup.net>" [ultimate]
Author: Patrick Schleizer <adrelanos@riseup.net>

Choose Version[edit]
Retrieve a list of available git tags.
git tag
Use git checkout to select the preferred version (or git branch) to build.
git checkout 14.0.1.3.8-stable
Replace 14.0.1.3.8 with the actual version chosen for the build: the stable, testers-only or developers version. Common sense is required when choosing the right version number. For example, the latest available version number is not necessarily the most stable or suitable. To learn more about current Whonix versions, follow the Whonix News Blog.
Clean Up and Sanitize[edit]
This step is also important for security.
Retrieve the list of extraneous files and folders. [4]
git clean -ndff
See if the output looks sane; it generally should, unless Whonix source code is modified by advanced users (who understand git better anyhow). If the output looks like the following, everything is fine.
Would remove packages/apparmor-profile-gwenview/ Would remove packages/kde-privacy/
Remove these folders.
git clean -dff
The output should show.
Removing packages/apparmor-profile-gwenview/ Removing packages/kde-privacy/
Be sure to check out the right commit for each git submodule.
git submodule update --init --recursive
Check there are no extraneous files. This is important for security.
git status
The output should show the following:
nothing to commit (working directory clean)
If the directory is not clean, the extra files should be removed first.
