Here is a revision that creates a mapping file (similar to mapping.txt, but that mirrors the formatting of "$OPENSSL ciphers -V" and that includes all cipher suites, even ones for which there is no OpenSSL name), loads the contents of the file into arrays, and then uses the arrays to implement openssl2rfc() and rfc2openssl(). |

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.
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:
https://github.com/drwetter/testssl.sh/milestones/2.7dev%20%282.8%29
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
