Below is a visual representation of the top 50 PGP keys in the Strong Set, sorted by fingerprint. Source code here. Each algorithm uses a deterministic algorithm on the fingerprint to draw the art. See this PDF for more information. In the case of old PGP fingerprints that are based on MD5 digests, the honeycomb and flag art will be incomplete, as they expect 160-bit digests, rather than 128-bit. Scanning the QR Code with an OpenPGP compatible application will import the PGP key from a key server. Check OpenKeychain for Android as an example.
