TLS Fingerprinting is still in its early days therefore the coverage of known prints is not too deep. The Trisul TLS Fingerprint App ships with a known fingerprint database of about 500 entries but you will likely find anywhere from 50-70% unknown fingerprints. We need a way to resolve prints to client ID.

Internally we use a Ruby TRP script that can automate this process. The script is available at mk_ja3print.rb
