## 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
|
|
* 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.
|
|
|
|
#### Current Development
|
|
|
|
Planned features in the release 2.7dev/2.8 are:

|
|
|
|
Done so far:
|
|
|
|
* Trust chain check against certificate stores from Apple (OS), Linux (OS),
|
|
Microsoft (OS), Mozilla (Firefox Browser), works for openssl >=1.0.1
|
|
* IPv6 (status: 80% working, details see
|
|
https://github.com/drwetter/testssl.sh/issues/11
|
|
* works on servers requiring a x509 certificate for authentication
|
|
* SSL Session ID check
|
|
* avahi/mDNS based name resolution
|
|
* HTTP2/ALPN protocol check
|
|
* Logging to a file / dir
|
|
* Logging to JSON + CSV
|
|
* check for multiple server certificates
|
|
* browser cipher simulation
|
|
* assistance for color-blind users
|
|
* Even more compatibility improvements for FreeBSD, RH-ish and F5 systems
|
|
* Considerable speed improvements for each cipher runs (-e/-E)
|
|
* more robust socket interface
|
|
* OpenSSL 1.1.0 compliant
|
|
* whole number of busg squashed
