Intro
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. In addition starting from version 3.0rc1 if you're offering a scanner based on testssl.sh as a public and / or paid service in the internet you need to mention to your audience that you're using this program and where to get this program from.
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.
