Verifying the release

Get benma's public key:

curl https://keybase.io/benma/pgp_keys.asc?fingerprint=2260e48288882c76afaa319d67a2b160f74db275 | gpg --import
# or via Tor hidden service
curl http://keybase5wmilwokqirssclfnsqrjdsi7jdir5wy7y7iu3tanwmtp6oid.onion/benma/pgp_keys.asc?fingerprint=2260e48288882c76afaa319d67a2b160f74db275 | gpg --import

Download the app for your platform and the corresponding .asc file and place them in the same folder.

We will verify the signature of the macOS release as an example. The other files are verified in the same way by replacing the filename.

To verify the signature, execute:

gpg --verify BitBox-4.21.1-macOS.zip.asc

You should see the following output:

gpg --verify BitBox-4.21.1-macOS.zip.asc
gpg: assuming signed data in 'BitBox-4.21.1-macOS.zip'
gpg: Signature made <DATE AND TIME>
gpg:                using RSA key 2D8876810AB092E451DCA894804538928C37EAE8
gpg: Good signature from "Marko Bencun <marko@shiftcrypto.ch>" [ultimate]
gpg:                 aka "Marko Bencun <mbencun+pgp@gmail.com>" [ultimate]

(The [ultimate] could say [unknown] or something else depending on your trust level.)
