NAME

sslsplit.conf - Configuration file for SSLsplit

DESCRIPTION

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

FILE FORMAT

BOOL
    Boolean value (yes/no).

STRING
    String.

CACert STRING
    Use CA cert (and key) to sign forged certs. Equivalent to -c command line option.

CAKey STRING
    Use CA key (and cert) to sign forged certs. Equivalent to -k command line option.

ClientCert STRING
    Use cert from pemfile when destination requests client certs. Equivalent to -a command line option.

ClientKey STRING
    Use key from pemfile when destination requests client certs. Equivalent to -b command line option.

CAChain STRING
    Use CA chain from pemfile (intermediate and root CA certs). Equivalent to -C command line option.

LeafKey STRING
    Use key from pemfile for generating leaf certs. Equivalent to -K command line option.
    Default: generate

LeafCRLURL STRING
    Use URL as CRL distribution point for all forged leaf certs. Equivalent to -q command line option.

LeafCertDir STRING
    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.

DefaultLeafCert STRING

WriteAllCertsDir STRING
    Write leaf key and all certificates to gendir. Equivalent to -W command line option.

Passthrough BOOL
    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

DHGroupParams STRING

Equivalent to -x command line option.

NATEngine STRING
    Specify default NAT engine to use. Equivalent to -e command line option.

User STRING
    Drop privileges to user. Equivalent to -u command line option.
    Default: nobody, if run as root

Group STRING
    Drop privileges to group. Equivalent to -m command line option.
    Default: Primary group of user

Chroot STRING
    chroot() to jaildir (impacts sni proxyspecs, see sslsplit(1)). Equivalent to -j command line option.

PidFile STRING
    Write pid to file. Equivalent to -p command line option.

ConnectLog STRING
    Connect log: log one line summary per connection to logfile. Equivalent to -l command line option.

ContentLog STRING
    Content log: full data to file or named pipe (excludes ContentLogDir/ContentLogPathSpec). Equivalent to -L command line option.

ContentLogDir STRING
    Content log: full data to separate files in dir (excludes ContentLog/ContentLogPathSpec). Equivalent to -S command line option.

ContentLogPathSpec STRING
    Content log: full data to sep files with % subst (excludes ContentLog/ContentLogDir). Equivalent to -F command line option.

LogProcInfo BOOL
    Look up local process owning each connection for logging. Equivalent to -i command line option.

PcapLog STRING
    Pcap log: packets to pcapfile (excludes PcapLogDir/PcapLogPathSpec). Equivalent to -X command line option.

PcapLogDir STRING
    Pcap log: packets to separate files in dir (excludes PcapLog/PcapLogPathSpec). Equivalent to -Y command line option.

PcapLogPathSpec STRING
    Pcap log: packets to sep files with % subst (excludes PcapLog/PcapLogDir). Equivalent to -y command line option.

MirrorIf STRING
    Mirror packets to interface. Equivalent to -I command line option.

MirrorTarget STRING
    Mirror packets to target address (used with MirrorIf). Equivalent to -T command line option.

MasterKeyLog STRING
    Log master keys to logfile in SSLKEYLOGFILE format. Equivalent to -M command line option.

Daemon BOOL
    Daemon mode: run in background, log error messages to syslog. Equivalent to -d command line option.

VerifyPeer BOOL
    Verify peer using default certificates.
    Default: no

AddSNIToCertificate BOOL
    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.
