CipherScan
==========
A very simple way to find out which SSL ciphersuites are supported by a target.
A very simple way to find out which SSL/TLS ciphersuites are supported by a target.
Cipherscan tests the ordering of the SSL/TLS ciphers on a given target, for all major versions of SSL and TLS. It also extracts some certificates informations. Cipherscan uses the `openssl s_client` command line to run the tests.
On Linux x86_64 run: ./cipherscan www.google.com:443
On any other *nix or *tux run: ./cipherscan -o /path/to/openssl www.google.com:443
