David Cooper 24cc3ae73f Fix #499
I forgot that `parse_tls_serverhello()` is also called by `client_simulation_sockets()`. Since PR #499 changed the input to `parse_tls_serverhello()`, the change needs to be made in `client_simulation_sockets()` as well.

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 master branch you find the stable version 2.8rc2 of the software, it superseds 2.6. Version 2.8 is currently being finalized . The 2.9dev branch is the developement -- 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 in 2.9dev

  • Support of supplying timeout value for openssl connect
  • TLS 1.2 protocol check via socket
  • Further TLS socket improvements (Handshake)

Planned in 2.9dev
