 #### Key features
 
 * Clear output: you can tell easily whether anything is good or bad
-* Ease of installation: It works for Linux, Darwin, FreeBSD and MSYS2/Cygwin out of the box: no need to install or configure something, no gems, CPAN, pip or the like.

-* Flexibility: You can test any SSL/TLS enabled and STARTTLS service, not only webservers at port 443

-* Toolbox: Several command line options help you to run YOUR test and configure YOUR output

 * Reliability: features are tested thoroughly
-* Verbosity: If a particular check cannot be performed because of a missing capability on your client side, you'll get a warning

 * Privacy: It's only you who sees the result, not a third party
-* Freedom: It's 100% open source. You can look at the code, see what's going on and you can change it.

 #### General
 
-Here in the master branch you find the development version of the software -- with new features and maybe some bugs. For the stable version and **a more thorough description of the command line options** please see [testssl.sh](https://testssl.sh/ "Go to the site with the stable version and more documentation").

-testssl.sh is working on every Linux/BSD distribution out of the box with some limitations of disabled features from the openssl client -- some workarounds are done with bash-socket-based checks. It also works on other unixoid system out of the box, supposed they have `/bin/bash` and standard tools like sed and awk installed. MacOS X and Windows (using MSYS2 or cygwin) work too. OpenSSL version >= 1 is a must.  OpenSSL version >= 1.0.2 is needed for better LOGJAM checks and to display bit strengths for key exchanges.
