SWURL contained for historical reasons trailing blanks for released versions. This caused an error in pr_boldurl --> html_out which didn't write the trailing style info and didn't close the href tag (travis complained.) This patch removes the trailing blank but it doesn't fix the error
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)
Installation
You can download testssl.sh by cloning this git repository:
git clone --depth 1 https://github.com/drwetter/testssl.sh.git
Or help yourself downloading the ZIP archive
https://github.com/drwetter/testssl.sh/archive/2.9.5.zip. Then testssl.sh --help will give you some help upfront. More help: see doc directory. Older
sample runs are at https://testssl.sh/.
Compatibility
testssl.sh is working on every Linux/BSD distribution out of the box. In 2.9.5 most
of the limitations of disabled features from the openssl client are gone due to bash-socket-based
checks. testssl.sh also works on other unixoid 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 installed. MacOS X and Windows (using MSYS2 or cygwin) work too. OpenSSL
version >= 1.0.2 is recommended, you will get further with earlier openssl versions in
this interim release though as most of the checks in 2.9 are done via sockets.

Status
2.9.5 is an interim release snapshot from the current 2.9dev version. It has reached a point which is considered to be mature enough for day-to-day usage before taking the next step in the development of this project.
2.9.5 has less bugs and has evolved considerably since 2.8.
Features implemented in 2.9.5
- TLS 1.2 protocol check via socket in production
- Way better coverage of ciphers as most checks are done via sockets, using bash sockets where ever possible
- Further tests via TLS sockets and improvements (handshake parsing, completeness, robustness)
- Testing 359 default ciphers (
testssl.sh -e/-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
- Non-flat JSON output 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'
- LUCKY13 and SWEET32 checks
- Ticketbleed check
- LOGJAM: now checking also for known DH parameters
- Support of supplying timeout value for
openssl connect-- useful for batch/mass scanning - Check for CAA RR
- Check for OCSP must staple
- Check for Certificate Transparency
- Check for session resumption (Ticket, ID)
- Better formatting of output (indentation)
- Choice showing the RFC naming scheme only
- Parallel mass testing
- File input for mass testing can be also in nmap grep(p)able (-oG) format
- Postgres und MySQL STARTTLS support
- Man page
