David Cooper d47601f413 Print unsupported ciphers in light grey 
This PR changes testssl.sh so that when ciphers are being listed in wide mode (i.e., using `neat_list()`) and the `--show-each` option is set, ciphers that are not available are printed in light grey, whereas ciphers that are available continue to be printed in black. This makes it easier to distinguish between ciphers that are available and those that are not (the "available/"not a/v" column remains).

This PR does not change the way that ciphers that are available are printed, but it includes a hook that would allow that to change. For example, for ciphers that are available, the name of the cipher suite could be printed in a different color depending on its quality (as is done for the "Negotiated cipher" in `run_server_preference()`). The same could be done for the "Encryption" and "Bits" columns.

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
  • Ease of installation: It works for Linux, Darwin, FreeBSD, NetBSD 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)

Status

Here in the 2.9dev 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 or https://github.com/drwetter/testssl.sh/wiki/Usage-Documentation.

Compatibility

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.

Update notification here or @ twitter.

Features implemented in 2.9dev

  • Support of supplying timeout value for openssl connect -- useful for batch/mass scanning
  • TLS 1.2 protocol check via socket
  • Further TLS socket improvements (handshake parsing, completeness, robustness)
  • non-flat JSON support
  • in file output (CSV, JSON flat, JSON non-flat) support of a minimum severity level (only above supplied level there will be output)
  • testing 359 default ciphers (testssl.sh -e) with a mixture of sockets and openssl. Same speed as with openssl only but addtional ciphers such as post-quantum ciphers, new CHAHA20/POLY1305, CamelliaGCM etc.
  • finding more TLS extensions via sockets
  • TLS Supported Groups Registry (RFC 7919), key shares extension
