This PR introduces the environment variable `CHILD_MASS_TESTING`, and uses it as an indicator that testssl.sh is running as a child within mass testing rather than using the `$APPEND` flag. It also makes a number of other changes to make the handling, of HTML, CSV, JSON, and log files consistent, and it fixes a number of bugs related to the generation of these files when mass testing is being performed. Please let me know if you disagree with any of the changes in this PR, or if you would prefer that it be broken up into multiple smaller PRs. Some of the changes are as follows: - When the `$APPEND` flag is true, all of these files are appended to and headers and footers are omitted. (Perhaps this should be changed. Appending to a log file isn't an issue, but appending to a JSON or HTML file without including headers or footers seems to just create an improperly formatted file). - Following the code in `prepare_logging()`, an error is printed and the program stops if the `$APPEND` flag is false and one of the files to be written to already exists. Some of the bugs fixed: Creating log files did not work with mass testing: - If `--logfile <logfile>` is used, then the parent and each child try to write to "logfile". - If `--logging` is used, then a log file is created for each child, but an oddly-named log file is also created for the parent. The one created by the parent contains the entire output. Plain JSON files: - When `--jsonfile <jsonfile>` is run, there is no comma separating the final finding for one child and the first finding for the next child. Pretty JSON files: - When `--jsonfile-pretty <jsonfile>` is called without mass testing, the "target host" line is empty, since `$NODE` has not yet been set. - When `--jsonfile <jsonfile>` is run with mass testing, there is no comma separating the final finding for one child and the first finding for the next child. In addition, `fileout_pretty_json_banner()` is never called, and the entries for individual tests have insufficient information to determine what is being tested (it lists "service" and "ip", but not port number). For the final issue, when mass testing is being performed and all output is being placed in a single file, I have the parent call `fileout_pretty_json_banner()`, but tell `fileout_pretty_json_banner()` to not include a "target host" or "port", but then have each child include a "target host" or "port" (when the "service" and "ip" are being printed). |

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, 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
