Intro

Build Status
Gitter

testssl.sh is a free command line tool which checks a server’s service on
any port for the support of TLS/SSL ciphers, protocols as well as some
cryptographic flaws.

Key features

  • Clear output: you can tell easily whether anything is good or bad.
  • Machine readable output.
  • No installation needed: Linux, OSX/Darwin, FreeBSD, NetBSD, MSYS2/Cygwin, WSL work out of the box. Only OpenBSD needs bash. No need to install or to configure something. No gems, CPAN, pip or the like.
  • A Dockerfile is provided, there’s also an offical container @ dockerhub.
  • Flexibility: You can test any SSL/TLS enabled and STARTTLS service, not only web servers at port 443.
  • Toolbox: Several command line options help you to run your test and configure your output.
  • Reliability: features are tested thoroughly.
  • 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.
  • The development is open (github) and participation is welcome.

License

This software is free. You can use it under the terms of GPLv2, see LICENSE.

Attribution is important for the future of this project -- also in the
internet. Thus if you’re offering a scanner based on testssl.sh as a public and/or
paid service in the internet you are strongly encouraged to mention to your audience
that you’re using this program and where to get this program from. That helps us
to get bugfixes, other feedback and more contributions.

Compatibility

testssl.sh is working on every Linux/BSD distribution out of the box. Latest by 2.9dev
most of the limitations of disabled features from the openssl client are gone
due to bash-socket-based checks. As a result you can also use e.g. LibreSSL or OpenSSL
1.1.1 . testssl.sh also works on other unixoid system out of the box, supposed they have
/bin/bash >= version 3.2 and standard tools like sed and awk installed. An implicit
(silent) check for binaries is done when you start testssl.sh . System V needs probably
to have GNU grep installed. MacOS X and Windows (using MSYS2, Cygwin or WSL) work too.

Update notification here or @ twitter.

Installation

You can download testssl.sh by cloning this git repository:

git clone --depth 1 https://github.com/drwetter/testssl.sh.git

and checkout the 3.0 branch. For this stable version you also can help yourself by downloading the ZIP or tar.gz archive. Then
just cd to the directory created (=INSTALLDIR) and run it off there.

Docker

Testssl.sh has minimal requirements. As stated you don’t have to install or build anything. You can just run it from the pulled/cloned directory. Still if you don’t want to pull the github repo to your directory of choice you can pull a container from dockerhub and run it:

docker run --rm -ti drwetter/testssl.sh:3.0 <your_cmd_line>

Or if you have cloned this repo you also can just cd to the INSTALLDIR and run

docker build .

followed by docker run -ti <ID> <your_cmd_line> where ID is the identifier in the last line from the build command like

 ---> 889fa2f99933
Successfully built 889fa2f99933

Status

This is the stable 3.0 version. That means you can and should use it for production and let us know if you encounter any additional bugs. Features implemented in 3.0 are listed in the Changelog. Support for 2.9.5 has been dropped.

The version 3.0 will receive bugfixes, labled as 3.0.1, 3.0.2 and so on. This will happen until 3.2 is released. Development is taking place in the 3.1dev branch which will eventually lead to version 3.2. We try to keep 3.1dev as solid as possible but things will certainly change in 3.1dev. Think of the 3.1dev branch like a rolling release.

Documentation

  • .. it is there for reading. Please do so :-) -- at least before asking questions. See man page in groff, html and markdown format in ~/doc/.
  • https://testssl.sh/ will help to get you started.
  • Albeit a bit older Will Hunt provides a longer, good description for the (older) version 2.8, including useful background info.

Contributing

Contributions are welcome! See CONTRIBUTING.md for details.
