Usage:  [ip:]port cert=certificate.pem [key=key.pem] [mode] [options...]

	The socket address where Squid will listen for client requests made
	over TLS or SSL connections. Commonly referred to as HTTPS.

	This is most useful for situations where you are running squid in
	accelerator mode and you want to do the SSL work at the accelerator level.

	You may specify multiple socket addresses on multiple lines,
	each with their own SSL certificate and/or options.

	Modes:

	   accel	Accelerator / reverse proxy mode

	   intercept	Support for IP-Layer interception of
			outgoing requests without browser settings.
			NP: disables authentication and IPv6 on the port.

	   tproxy	Support Linux TPROXY for spoofing outgoing
			connections using the client IP address.
			NP: disables authentication and maybe IPv6 on the port.

	   ssl-bump	For each intercepted connection allowed by ssl_bump
			ACLs, establish a secure connection with the client and with
			the server, decrypt HTTPS messages as they pass through
			Squid, and treat them as unencrypted HTTP messages,
			becoming the man-in-the-middle.

			An "ssl_bump server-first" match is required to
			fully enable bumping of intercepted SSL	connections.

			Requires tproxy or intercept.

	Omitting the mode flag causes default forward proxy mode to be used.

	SSL Options:

	   cert=	Path to SSL certificate (PEM format).

	   key=		Path to SSL private key file (PEM format)
			if not specified, the certificate file is
			assumed to be a combined certificate and
			key file.

	   version=	The version of SSL/TLS supported
			    1	automatic (default)
			    2	SSLv2 only
			    3	SSLv3 only
			    4	TLSv1 only

	   cipher=	Colon separated list of supported ciphers.

	   options=	Various SSL engine options. The most important
			being:
			    NO_SSLv2  Disallow the use of SSLv2
			    NO_SSLv3  Disallow the use of SSLv3
			    NO_TLSv1  Disallow the use of TLSv1
			    SINGLE_DH_USE Always create a new key when using
				      temporary/ephemeral DH key exchanges
			See src/ssl_support.c or OpenSSL SSL_CTX_set_options
			documentation for a complete list of options.

	   clientca=	File containing the list of CAs to use when
			requesting a client certificate.

	   cafile=	File containing additional CA certificates to
			use when verifying client certificates. If unset
			clientca will be used.

	   capath=	Directory containing additional CA certificates
			and CRL lists to use when verifying client certificates.

	   crlfile=	File of additional CRL lists to use when verifying
			the client certificate, in addition to CRLs stored in
			the capath. Implies VERIFY_CRL flag below.

	   dhparams=	File containing DH parameters for temporary/ephemeral
			DH key exchanges.

	   sslflags=	Various flags modifying the use of SSL:
			    DELAYED_AUTH
				Don't request client certificates
				immediately, but wait until acl processing
				requires a certificate (not yet implemented).
			    NO_DEFAULT_CA
				Don't use the default CA lists built in
				to OpenSSL.
			    NO_SESSION_REUSE
				Don't allow for session reuse. Each connection
				will result in a new SSL session.
			    VERIFY_CRL
				Verify CRL lists when accepting client
				certificates.
			    VERIFY_CRL_ALL
				Verify CRL lists for all certificates in the
				client certificate chain.

	   sslcontext=	SSL session ID context identifier.

	   generate-host-certificates[=<on|off>]
			Dynamically create SSL server certificates for the
			destination hosts of bumped SSL requests.When
			enabled, the cert and key options are used to sign
			generated certificates. Otherwise generated
			certificate will be selfsigned.
			If there is CA certificate life time of generated
			certificate equals lifetime of CA certificate. If
			generated certificate is selfsigned lifetime is three
			years.
			This option is enabled by default when SslBump is used.
			See the sslBump option above for more information.

	   dynamic_cert_mem_cache_size=SIZE
			Approximate total RAM size spent on cached generated
			certificates. If set to zero, caching is disabled. The
			default value is 4MB.

	See http_port for a list of available options.
