-## PGP keys of builders and Developers
-
-The file `keys.txt` contains fingerprints of the public keys of builders and
-active developers.
-
-The keys are mainly used to sign git commits or the build results of builds.
-
-The most recent version of each pgp key can be found on most pgp key servers.
-
-Fetch the latest version from the key server to see if any key was revoked in
-the meantime.
-To fetch the latest version of all pgp keys in your gpg homedir,
-
-```sh
-gpg --refresh-keys
-```
-
-To fetch keys of builders and active developers, feed the list of fingerprints
-of the primary keys into gpg:
-
-On \*NIX:
-```sh
-while read fingerprint keyholder_name; do gpg --keyserver hkps://keys.openpgp.org --recv-keys ${fingerprint}; done < ./keys.txt
-```
-
-On Windows (requires Gpg4win >= 4.0.0):
-```
-FOR /F "tokens=1" %i IN (keys.txt) DO gpg --keyserver hkps://keys.openpgp.org --recv-keys %i
-```
-
-Add your key to the list if you provided Guix attestations for two major or
-minor releases of Dash Core.
