DESCRIPTION

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

UNIQUE FEATURES

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?

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

  o-saft.pl --help
