Struct Ja4Fingerprint 

pub struct Ja4Fingerprint { /* private fields */ }

The JA4 fingerprint of one ClientHello.

Ja4Fingerprint::ja4 is computed up front, since it is the form that is normally logged; the raw and original-order forms are built when asked for.

Implementations

impl Ja4Fingerprint

pub fn from_client_hello(body: &[u8]) -> Option<Self>

Fingerprints a ClientHello message body, as returned by read_client_hello. None when it is malformed: a fingerprint of a broken hello would not match what any other tool computes.

pub fn ja4(&self) -> &str

JA4, e.g. t13d1516h2_8daaf6152771_e5627efa2ab1.

pub fn ja4_r(&self) -> String

JA4_r: the sorted lists themselves instead of their hashes.

pub fn ja4_o(&self) -> String

JA4_o: hashed like JA4, but over the lists in the order the client sent them, SNI and ALPN included.

pub fn ja4_ro(&self) -> String

JA4_ro: the lists in the order the client sent them, unhashed.
