A small JA3 TLS fingerprinting library written in Rust.
This crate enables a consumer to fingerprint the ClientHello portion of a TLS handshake. It can hash TLS handshakes over IPv4 and IPv6. It heavily depends on the tls-parser project from Rusticata.
It supports generating fingerprints from packet capture files as well as live-captures on a network interface, both using libpcap.
See the original JA3 project for more information.
Example of fingerprinting a packet capture file:
```rust use ja3::Ja3;
let mut ja3 = Ja3::new("test.pcap") .process_pcap() .unwrap();
// Now we have a Vec of Ja3Hash objects for hash in ja3 { println!("{}", hash); } ```
Example of fingerprinting a live capture:
```rust use ja3::Ja3;
let mut ja3 = Ja3::new("eth0") .process_live(|x| { println!("{}", x); }) .unwrap();
```
