Thomas Ward 03d8ba9b81 Update OpenSSL reqs - LOGJAM checks need 1.0.2+
To effectively analyze the LOGJAM risks, and to display the bitstrength on the DH/ECDH negotiated ciphers, OpenSSL 1.0.2+ is needed.  With anything under 1.0.2 (and greater than 1.0.0), the bitstrengths are not displayed as OpenSSL is 'too old' (as referred to in the script itself when 1.0.2 is newer than what's available).

I suggest that we keep a note that >= 1.0.2 is needed for LOGJAM checks.

Intro

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. It's designed to provide clear output for your "is this good or bad" decision.

It is working on every Linux 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 BSD and other Unices out of the box, supposed they have /bin/bash and standard tools like sed and awk installed. MacOS X and Windows (using MSYS2) work too. OpenSSL version >= 1 is highly recommended. OpenSSL version >= 1.0.2 is needed for LOGJAM checks.

On github you will find in the master branch the development version of the software -- with new features and maybe some bugs. For the stable version and a more thorough description of the software please see testssl.sh.

New features in the upcoming stable release 2.6 are:

  • display matching key (HPKP)
  • LOGJAM: check DHE_EXPORT cipher and display DH(/ECDH) bits in wide mode on negotiated ciphers
  • Run in default mode through all ciphers
  • wide mode for several checks

Contributions, feedback, also bug reports are welcome! For contributions please note: One patch per feature -- bug fix/improvement. Please test your changes thouroughly as reliability is important for this project.
