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

o-saft.pl requires following Perl modules:
| Module | Version |
|---|---|
| Net::SSLeay | (prefered >= 1.51, recommended 1.85) |
| IO::Socket::SSL | (prefered >= 1.37, recommended 2.002) |
| IO::Socket::INET | (prefered >= 2.31) |
| Net::DNS | (prefered >= 0.65, for --mx option only) |
O-Saft 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
INSTALL.sh --clean
INSTALL.sh --check
INSTALL.sh --n /path/to/install --force
INSTALL.sh /path/to/install --force
There're no dependencies to other perl modules for checkAllCiphers.pl
so the test of all ciphers will work with it.
The modules Net::SSLinfo, Net::SSLhello are part of O-Saft and should
be installed in ./Net .
