O-Saft

This is O-Saft's documentation as you get with

o-saft.pl --help

NAME

o-saft.pl - OWASP SSL audit for testers

OWASP SSL advanced forensic tool

DESCRIPTION

This tools lists information about remote target's SSL certificate

and tests the remote target according given list of ciphers.

Note: Throughout this description $0 is used as an alias for the

program name "o-saft.pl" .

SYNOPSIS

o-saft.pl [COMMANDS ..] [OPTIONS ..] target [target target ...]

Where [COMMANDS] and [OPTIONS] are described below and target

is a hostname either as full qualified domain name or as IP address.

Multiple commands and targets may be combined.

All commands and options can also be specified in a rc-file, see

RC-FILE below.

QUICKSTART

Before going into a detailed description of the purpose and usage,

here are some examples of the most common use cases:

Show supported (enabled) ciphers of target:

   o-saft.pl +cipher --enabled example.tld

Show details of certificate and connection of target:

   o-saft.pl +info example.tld

Check certificate, ciphers and SSL connection of target:

   o-saft.pl +check example.tld

List all available commands:

   o-saft.pl --help=commands

For more specialised test cases, refer to the COMMANDS and OPTIONS

sections below.

If no command is given, +cipher is used.

WHY?

Why a new tool for checking SSL security and configuration when there

are already a dozen or more such tools in existence (circa 2012)?

Currently available tools suffer from some or all of following issues:

* lack of tests of unusual ciphers

* lack of tests of unusual SSL certificate configurations

* may return different results for the same checks on a given target

* missing tests for modern SSL/TLS functionality

* missing tests for specific, known SSL/TLS vulnerabilities

* no support for newer, advanced, features e.g. CRL, OCSP, EV

* limited capability to create your own customised tests

Other reasons or problems are that they are either binary and hence

not portable to other (newer) platforms.

In contrast to (all?) most other tools, including openssl, it can be

used to `ask simple questions' like `does target support STS' just by

calling:

   o-saft.pl +cipher +hsts_sts example.tld
