Hitch — high performance TLS proxy

Synopsis

hitch [OPTIONS] [PEM]

Description

Hitch is a network proxy that terminates TLS/SSL connections and forwards the unencrypted traffic to some backend. It's designed to handle 10s of thousands of connections efficiently on multicore machines.

Hitch has very few features -- it's designed to be paired with an intelligent backend like Varnish Cache. It maintains a strict 1:1 connection pattern with this backend handler so that the backend can dictate throttling behavior, maximum connection behavior, availability of service, etc.

The only required argument is a path to a PEM file that contains the certificate (or a chain of certificates) and private key. It should also contain DH parameter if you wish to use Diffie-Hellman cipher suites.

Command Line Arguments

--config=FILE
Load configuration from specified file. See hitch.conf(5) for details.
--tls
All TLS versions, no SSLv3 (deprecated). See config file setting tls-protos.
--ssl
enable SSLv3 (deprecated). See config file setting tls-protos.
-c
--ciphers=SUITE
Sets allowed ciphers (Default: "")
-e
--ssl-engine=NAME
Sets OpenSSL engine (Default: "")
-O
--prefer-server-ciphers
Prefer server list order
--client
Enable client proxy mode
-b
--backend=[HOST]:PORT Backend [connect] (default is "[127.0.0.1]:8000")
-f
--frontend=[HOST]:PORT[+CERT] Frontend [bind] (default is "[*]:8443") (Note: brackets are mandatory in endpoint specifiers.)
-n
--workers=NUM
Number of worker processes (Default: 1)
-B
--backlog=NUM
Set listen backlog size (Default: 100)
-k
--keepalive=SECS
TCP keepalive on client socket (Default: 3600)
-r
--chroot=DIR
Sets chroot directory (Default: "")
-u
--user=USER
Set uid/gid after binding the socket (Default: "")
-g
--group=GROUP
Set gid after binding the socket (Default: "")
-q
--quiet
Be quiet; emit only error messages
-s
--syslog
Send log message to syslog in addition to stderr/stdout
--syslog-facility=FACILITY
Syslog facility to use (Default: "daemon")
--daemon
Fork into background and become a daemon; this also sets the --quiet option (Default: off)
--write-ip
Write 1 octet with the IP family followed by the IP address in 4 (IPv4) or 16 (IPv6) octets little-endian to backend before the actual data (Default: off)
--write-proxy-v1
Write HaProxy's PROXY v1 (IPv4 or IPv6) protocol line before actual data (Default: off)
--write-proxy-v2
Write HaProxy's PROXY v2 binary (IPv4 or IPv6) protocol line before actual data (Default: off)
--write-proxy
Equivalent to --write-proxy-v2. For PROXY version 1 use --write-proxy-v1 explicitly
--proxy-proxy
Proxy HaProxy's PROXY (IPv4 or IPv6) protocol line before actual data (PROXY v1 only) (Default: off)
--alpn-protos=LIST
Sets the protocols for ALPN/NPN negotiation, given by a comma separated list. If this is not set explicitly, ALPN/NPN will not be used. Requires OpenSSL 1.0.1 for NPN and OpenSSL 1.0.2 for ALPN.
--sni-nomatch-abort
Abort handshake when client submits an unrecognized SNI server name (Default: off)
--ocsp-dir=DIR
Set OCSP staple cache directory This enables automated retrieval and stapling of OCSP responses (Default: "")
-t
--test
Test configuration and exit
-p
--pidfile=FILE
PID file
-V
--version
Print program version and exit
-h
--help
This help message
