========== ==========
A very simple way to find out which SSL ciphersuites are supported by a target. A very simple way to find out which SSL ciphersuites are supported by a target.
Run: ./cipherscan www.google.com:443 On Linux x86_64 run: ./cipherscan www.google.com:443
And watch. On any other *nix or *tux run: ./cipherscan -o /path/to/openssl www.google.com:443
and watch.
The newer your version of openssl, the better results you'll get. Versions
of OpenSSL below 1.0.1 don't support TLS1.2 ciphers, elliptic curves, etc... Build your own or test what your system's OpenSSL supports.
Cipherscan should work fine on Linux, Mac OS X, Solaris, Illumos, SmartOS, OpenIndiana if you specify a an openssl binary with -o.
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 Options
------- -------
Enable benchmarking by setting DOBENCHMARK to 1 at the top of the script. Enable benchmarking by passing -b|--benchmark
You can use one of the options below (only one. yes, I know...) You can the options below.
Use '-v' to get more stuff to read. -a | --allciphers Test all known ciphers individually at the end.
-b | --benchmark Activate benchmark mode.
Use '-a' to force openssl to test every single cipher it know. -h | --help Shows this help text.
-j | --json Output results in JSON format.
Use '-json' to output the results in json format -o | --openssl /path/to/the/openssl binary you want to use.
-v | --verbose Increase verbosity.
``` ```
$ ./cipherscan -json www.google.com:443 linux $ ./cipherscan -json www.google.com:443
``` ```
Example Example
------- -------
Testing plain SSL/TLS:
``` ```
$ ./cipherscan www.google.com:443 $ ./cipherscan www.google.com:443
