About this fingerprint

JA4 is a fingerprint of the TLS Client Hello: the version, cipher suites, extensions and signature algorithms a client offers when it opens an HTTPS connection. Clients built on the same library and version produce the same JA4, which makes it a durable handle on the tool behind the traffic.
