    --help            brief help message

    --listen          listen on (default
    --backend         backend address or path to unix socket (default

    --backlog         backlog size (default 128)

    --cert_file       path to certificate file (may contain a private key too)
    --key_file        path to private key file
    --cert_password   certificate password (promts unless value provided)

    --method          protocol parser to use ("SSLv2" | "SSLv3" | "TLSv1" | "any")
    --cipher_list     list of ciphers to use ("AES:ALL:!aNULL:!eNULL:+RC4:@STRENGTH")

    --protocol        underlying protocol ("raw" | "http")

    --user            drop privileges to user (ID or name)

When option C<cert_file> is omitted default testing certificate is used.


TLS/SSL proxy in front of the application creates a transparent encryption
