CipherScan

A very simple way to find out which SSL ciphersuites are supported by a target.

Run: ./CipherScan.sh www.google.com:443 And watch.

The newer your version of openssl, the better results you'll get. Older versions of OpenSSL don't support TLS1.2 ciphers, elliptic curves, etc... Build Your Own!

Options

Enable benchmarking by setting DOBENCHMARK to 1 at the top of the script.

Use '-v' to get more stuff to read.

Use '-a' to force openssl to test every single cipher it know.

Example

$ ./CiphersScan.sh google.com:443
