A (probably outdated) snapshot of the 57North web-of-trust

Spacekeys is a small project by irl to visualise the 57North web-of-trust for OpenPGP keys. It uses sig2dot and graphviz to produce the visualisations. Remember that you should not trust Spacekeys for key discovery, you should always check that you have a trust path from your key via trusted people. There is 'no verification' when new keys are added beyond a basic sanity check.

Adding your key to Spacekeys

Send an email to [|] to request that your key fingerprint is added (don't forget to include the fingerprint!).


The bulk of the logic is contained in a single shell script run by cron job. The KEYS environment variable is set to contain a space separated list of OpenPGP fingerprints.
