Verify the virtual machine images using Windows
Windows using Gpg4win
GnuPG, a common free software implementation of OpenPGP has versions and graphical frontends for Windows.
Gpg4win, for Windows. Getting a GnuPG version for Windows in a secure way.
You will find on this websites detailed documentation on how to install and use them.
After installing Gpg4win, download the Whonix Signing Key.
Using Kleopatra is really cumbersome for reasons stated below. Therefore it is recommended to rather use gpg #command line.
As long as the signing key is only listed under "other certificates" in Kleopatra, you will get "Not enough information to check signature validity". The signing key needs to be listed under "trusted certificates". To do that, you need to create your own OpenPGP key first. You could do that using (Kleopatra -> File -> New Certificate). To sign Whonix's singing key, right click on it and click "Certify Certificate". Creating local signature suffices.
If you see "Not enough information to check signature validity" as shown below.
Then you either did not import Whonix's signing key or you did not sign Whonix's signing key with your own key.
If you see.
Signature valid. Signed on 2014-04-13 06:52 with unknown certificate 0x63979B28A6F37C43BE30AFA1CB8D50BB77BB3C48
|Check if the gpg signature timestamp makes sense. For example, simply said, if you previously saw a signature from in 2015 and now you are seeing a signature from 2014, then you could be target of a rollback (downgrade) or indefinite freeze attack. |
|Note, OpenPGP signatures do sign files. Not file names. |
For this reasons, you are probably better off using gpg command line. Instructions similar to:
