This tools lists information about remote target's SSL certificate and tests the remote target according given list of ciphers.

• working in closed environments, i.e. without internet connection
• checking availability of ciphers independent of installed library
• checking for all possible ciphers (up to 65535 per SSL protocol)
• needs just perl without modules for checking ciphers and protocols
• mainly same results on all platforms

Why a new tool for checking SSL when there already exist a dozens or more good tools in 2012? Some (but not all) reasons are:

• lack of tests of unusual ciphers
• different results returned for the same check on same target
• missing functionality (checks) according modern SSL/TLS
• lack of tests of unusual (SSL, certificate) configurations
• (mainly) missing feasability to add own tests

For more details, please use:

  o-saft.pl --help

or read the source ;-)

• penetration testers
• administrators

o-saft.pl requires following Perl modules:

It can be executed from within the unpacked or cloned directory, installation is not necessary. However, a INSTALL.sh script will be provided, which can be called as follows:

  INSTALL.sh /path/to/install
  INSTALL.sh --check

For more details on installation, please see:

  INSTALL.sh --help

There're no dependencies to other Perl modules for checkAllCiphers.pl so the test of all ciphers will work with it. The modules SSLinfo, SSLhello beside som others, are part of the tool and should be installed in ./lib .

Version 24.01.24 is a major redesign (refactoring) of the project. The top directory now contains the main tools only. All modules, documentation and (user) contributed tools are in sub-directories. These changes are also reflected in the directories available at github.

If older versions should be used, please get the correspondig o-saft.tgz from github's releases, see: https://github.com/OWASP/O-Saft/releases (as of January 2024).
