`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
|
|
* 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.
|
|
* Heck, even the development is open (github)
|
|
|
|
####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.

|
|
|
|
Done so far:
|
|
|
|
* Trust chain check against certificate stores from java, linux (system), microsoft, mozilla (works for openssl >=1.0.2)
|
|
* IPv6 (status: 80% working, details see https://github.com/drwetter/testssl.sh/issues/11
|
|
* works on servers requiring a client certificate for authentication
|
|
* SSL Session ID check
|
|
* avahi/mDNS based name resolution
|
|
* Logging to a file
|
|
* Even more compatibilty improvements for FreeBSD, RH-ish and F5 systems
