The Postgres protocol uses STARTTLS with a custom start packet. This
functionality is supported by openssl s_client in the current openssl
master branch but not yet in any released version.
This patch detects whether the given openssl binary supports postgres
and runs the default tests against a postgres server.
Example of no openssl support:
~/bin/testssl$ ./testssl.sh --quiet
--openssl=/opt/openssl/openssl-1.1.0c/bin/openssl --starttls=postgres
test.postgres.server.com:5432
Start 2016-12-07 18:03:24 -->> ip.add.re.ss:5432
(test.postgres.server.com:5432) <<--
Fatal error: Your /opt/openssl/openssl-1.1.0c/bin/openssl does not
support the "-starttls postgres" option
Example of openssl support:
~/bin/testssl$ ./testssl.sh --quiet
--openssl=/opt/openssl/openssl-2016-12-07/bin/openssl --startt ls=postgres
test.postgres.server.com:5432
Start 2016-12-07 18:06:03 -->> ip.add.re.ss:5432
(test.postgres.server.com:5432) <<--
Service set: STARTTLS via POSTGRES
Testing protocols (via openssl, SSLv2 via sockets)
SSLv2 not offered (OK)
SSLv3 offered (NOT ok)
TLS 1 offered
TLS 1.1 offered
TLS 1.2 offered (OK)
SPDY/NPN (SPDY is an HTTP protocol and thus not tested here)
HTTP2/ALPN (HTTP/2 is a HTTP protocol and thus not tested
here)

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 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 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 TLS socket improvements (handshake parsing, completeness, robustness)
- non-flat JSON support
- in file output (CSV, JSON flat, JSON non-flat) support of a minimum severity level (only above supplied level there will be output)
- 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. - finding more TLS extensions via sockets
- TLS Supported Groups Registry (RFC 7919), key shares extension
