Uses of ClientHello in org.microproxy

Methods in org.microproxy that return ClientHello

Modifier and Type	Method	Description
ClientHello	FlowContext.getClientHello()	The TLS ClientHello the client sent to start the intercepted (or tunnelled) session this flow belongs to: after a CONNECT whose client was asked for one, and on a transparent TLS connection.

Methods in org.microproxy with parameters of type ClientHello

Modifier and Type	Method	Description
default boolean	HttpFilters.proxyToServerAllowMitm(ClientHello clientHello)	Whether this CONNECT (or transparent TLS connection) may be intercepted, now that the client's TLS ClientHello is known: return false to tunnel the bytes untouched, so the client sees the real server's certificate.
boolean	HttpFiltersBuilder.Built.proxyToServerAllowMitm(ClientHello clientHello)
boolean	HttpFiltersChain.Chained.proxyToServerAllowMitm(ClientHello clientHello)
default boolean	MitmManager.shouldIntercept(ClientHello clientHello, FlowContext flow)	Whether to intercept a TLS connection, once its client's ClientHello is known: return false to tunnel it untouched, so the client sees the real server's certificate.
default void	ActivityTracker.transparentQuicFlowDecided(FlowContext flowContext, ClientHello clientHello, boolean intercepted, String reason)	Called when the transparent QUIC listener (HttpProxyServerBootstrap.withTransparentQuicPort(int)) has decided what to do with a new client flow, from its ClientHello: intercept it (its HTTP/3 requests then come as for any client), or relay its datagrams to the server untouched.

Method parameters in org.microproxy with type arguments of type ClientHello

Modifier and Type	Method	Description
HttpFiltersBuilder	HttpFiltersBuilder.allowMitmFor(Predicate<? super ClientHello> allow)	Whether a TLS connection may be intercepted, decided from the client's ClientHello (its server name and ALPN protocols); see HttpFilters.proxyToServerAllowMitm(ClientHello).

Uses of ClientHello in org.microproxy.extras

Methods in org.microproxy.extras with parameters of type ClientHello

Modifier and Type	Method	Description
static String	TlsFingerprints.ja3(ClientHello hello)	The JA3 fingerprint: the lowercase hex MD5 of TlsFingerprints.ja3String(org.microproxy.ClientHello).
static String	TlsFingerprints.ja3String(ClientHello hello)	The JA3 string: version,ciphers,extensions,groups,point_formats, each list's values in decimal, in the hello's order, separated by -.
static String	TlsFingerprints.ja4(ClientHello hello)	The JA4 fingerprint of a hello sent over TCP.
static String	TlsFingerprints.ja4(ClientHello hello, boolean quic)	The JA4 fingerprint: a_b_c, where a is the transport (t for TCP, q for QUIC), the highest TLS version offered (13, 12, ...), d with SNI or i without, the counts of cipher suites and extensions (two digits each), and the first and last characters of the first ALPN protocol (00 without); b is the first 12 hex digits of the SHA-256 of the sorted cipher suites (4-digit hex, comma separated); c the same of the sorted extensions without SNI and ALPN, followed by _ and the signature algorithms in their order when there are any.
