sslsplit.conf - Configuration file for SSLsplit

The file sslsplit.conf configures SSLsplit, sslsplit(1).

The file consists of comments and options with arguments. Each line which starts with a hash (#) symbol is ignored by the parser. Options and arguments are of the form Option Argument. The arguments are of the following types:

Boolean value (yes/no).
String.

When an option is not used (hashed or doesn't exist in the configuration file) sslsplit takes a default action. If an option does not have a command line equivalent, -o opt=val option can be used to override it on the command line.

Use CA cert (and key) to sign forged certs. Equivalent to -c command line option.
Use CA key (and cert) to sign forged certs. Equivalent to -k command line option.
Use cert from pemfile when destination requests client certs. Equivalent to -a command line option.
Use key from pemfile when destination requests client certs. Equivalent to -b command line option.
Use CA chain from pemfile (intermediate and root CA certs). Equivalent to -C command line option.
Use key from pemfile for generating leaf certs. Equivalent to -K command line option.
Default: generate
Use URL as CRL distribution point for all forged leaf certs. Equivalent to -q command line option.
Use cert+chain+key PEM files from certdir to target all sites matching the common names (non-matching: generate if CA). Equivalent to -t command line option.
Use cert+chain+key from PEM file for leaf certificates if there is no match in LeafCertDir. Equivalent to -A command line option.
Write leaf key and only generated certificates to gendir. Equivalent to -w command line option.
Write leaf key and all certificates to gendir. Equivalent to -W command line option.
Deny all OCSP requests on all proxyspecs. Equivalent to -O command line option.
Passthrough SSL connections if they cannot be split because of client cert auth or no matching cert and no CA. Equivalent to -P command line option.
Default: drop
Use DH group params from pemfile. Equivalent to -g command line option.
Default: keyfiles or auto
Use ECDH named curve. Equivalent to -G command line option.
Default: prime256v1
Enable/disable SSL/TLS compression on all connections. Equivalent to -Z command line option.
Force SSL/TLS protocol version only. Equivalent to -r command line option.
Default: all
Disable SSL/TLS protocol version. Equivalent to -R command line option.
Default: none
Use the given OpenSSL cipher suite spec. Equivalent to -s command line option.
Default: ALL:-aNULL
The OpenSSL engine to activate, either the ID or the full path to the shared library implementing the engine. If an ID is given, the engine needs to be known to the system-wide OpenSSL configuration. Only available if built against a version of OpenSSL with engine support. Equivalent to -x command line option.
Specify default NAT engine to use. Equivalent to -e command line option.
Drop privileges to user. Equivalent to -u command line option.
Default: nobody, if run as root
Drop privileges to group. Equivalent to -m command line option.
Default: Primary group of user
chroot() to jaildir (impacts sni proxyspecs, see sslsplit(1)). Equivalent to -j command line option.
Write pid to file. Equivalent to -p command line option.
Connect log: log one line summary per connection to logfile. Equivalent to -l command line option.
Content log: full data to file or named pipe (excludes ContentLogDir/ContentLogPathSpec). Equivalent to -L command line option.
Content log: full data to separate files in dir (excludes ContentLog/ContentLogPathSpec). Equivalent to -S command line option.
Content log: full data to sep files with % subst (excludes ContentLog/ContentLogDir). Equivalent to -F command line option.
Look up local process owning each connection for logging. Equivalent to -i command line option.
Pcap log: packets to pcapfile (excludes PcapLogDir/PcapLogPathSpec). Equivalent to -X command line option.
Pcap log: packets to separate files in dir (excludes PcapLog/PcapLogPathSpec). Equivalent to -Y command line option.
Pcap log: packets to sep files with % subst (excludes PcapLog/PcapLogDir). Equivalent to -y command line option.
Mirror packets to interface. Equivalent to -I command line option.
Mirror packets to target address (used with MirrorIf). Equivalent to -T command line option.
Log master keys to logfile in SSLKEYLOGFILE format. Equivalent to -M command line option.
Daemon mode: run in background, log error messages to syslog. Equivalent to -d command line option.
Debug mode: run in foreground, log debug messages on stderr. Equivalent to -D command line option.
Verify peer using default certificates.
Default: no
When disabled, never add the SNI to forged certificates, even if the SNI provided by the client does not match the server certificate's CN/SAN. Helps pass the wrong.host test at https://badssl.com.
Default: yes
Proxy specification: type listenaddr+port [natengine|targetaddr+port|"sni"+port]. Multiple specs are allowed, one on each line.
