<commit_before>CipherScan
==========
A very simple way to find out which SSL ciphersuites are supported by a target.

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
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.

Build OpenSSL with ChaCha20-Poly1305 support (Optional)
-------------------------------------------------------

The OpenSSL binary in this repository is built for 64bit Linux. If you wish to build a version with the same features for your own platform, [the snapshot from the OpenSSL gitweb view](http://git.openssl.org/gitweb/?p=openssl.git;a=tree;h=161b23361778c155f9c174694b1db2506a2e0b52;hb=9a8646510b) and build it like this:

```
./config no-shared
make
```

And get the binary from `app/openssl`. (`./config` will ask you to run `make depend` which will fail - for our purposes this step is not required)

Options
-------

```
-a | --allciphers   Test all known ciphers individually at the end.
-b | --benchmark    Activate benchmark mode.
-d | --delay        Pause for n seconds between connections
-D | --debug        Output ALL the information.
-h | --help         Shows this help text.
-j | --json         Output results in JSON format.
-o | --openssl      path/to/your/openssl binary you want to use.
-v | --verbose      Increase verbosity.
```
