Dirk e8b5a82c7e Considerable reliability improvements for ticketbleed: if a handshake server hello 
was received, testssl.sh tries 3 times to get memory from the server, If
the server returns different memory it's highly likely vulnerable.
(some more vulnerable devices to test against would be appreciated).

This is the default now -- all other hosts are mostly labled as OK.

Parsing SERVICE should be a little faster and more reliable

Increased needed debug level for output @ parse_tls_serverhello

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. In 2.9dev most of the limitations of disabled features from the openssl client are gone due to bash-socket-based checks. testssl.sh also works on otherunixoid system out of the box, supposed they have /bin/bash and standard tools like sed and awk installed. System V needs to have GNU versions of grep and sed 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 tests via TLS sockets and improvements (handshake parsing, completeness, robustness)
  • Finding more TLS extensions via sockets
  • Using bash sockets where ever possible
  • TLS Supported Groups Registry (RFC 7919), key shares extension
  • Non-flat JSON support
  • File output (CSV, JSON flat, JSON non-flat) supports a minimum severity level (only above supplied level there will be output)
  • Native HTML support instead going through 'aha'
  • 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.
  • LUCKY13 and SWEET32 checks
  • LOGJAM: now checking also for known DH parameters
  • Check for CAA RR
  • Check for OCSP must staple
  • Better formatting of output (indentation)
  • Choice showing the RFC naming scheme only
