# Seriously! The threat is you run this code on your computer and input could be /

|
|
|
|
# HISTORY:
|
|
# Back in 2006 it all started with a few openssl commands...
|
|
# That's because openssl is a such a good swiss army knife (see e.g.
|
|
# wiki.openssl.org/index.php/Command_Line_Utilities) that it was difficult to resist
|
|
# wrapping some shell commands around it, which I used for my pen tests. This is how
|
|
# everything started.
|
|
# Now it has grown up, it has bash socket support for some features which basically replacing
|
|
# more and more functions of OpenSSL and will serve as some kind of library in the future.
|
|
# The socket checks in bash may sound cool and unique -- they are -- but probably you
|
|
# can achieve e.g. the same result with my favorite interactive shell: zsh (zmodload zsh/net/socket
|
|
# -- checkout zsh/net/tcp) too!
|
|
# /bin/bash though is way more often used within Linux and it's perfect
|
|
# for cross platform support, see MacOS X and also under Windows the MSYS2 extension or Cygwin.
|
|
# Cross-platform is one of the three main goals of this script. Second: Ease of installation.
|
|
# No compiling, install gems, go to CPAN, use pip etc. Third: Easy to use and to interpret
|
|
# the results.
|
|
|
|
# Did I mention it's open source?
|
|
|
|
# Q: So what's the difference to www.ssllabs.com/ssltest/ or sslcheck.globalsign.com/ ?
|
|
# A: As of now ssllabs only check 1) webservers 2) on standard ports, 3) reachable from the
|
|
# internet. And those examples above 4) are 3rd parties. If these restrictions are all fine
|
|
# with you and you need a management compatible rating -- go ahead and use those.
|
|
|
|
# But also if your fine with those restrictions: testssl.sh is meant as a tool in your hand
|
|
# and it's way more flexible.
|
|
#
|
|
# Oh, and did I mention testssl.sh is open source?
|
|
|
|
# Note that up to today there were a lot changes for "standard" openssl
|
|
# binaries: a lot of features (ciphers, protocols, vulnerabilities)
|
|
# are disabled as they'll impact security otherwise. For security
|
|
# testing though we need all broken features. testssl.sh will
|
|
# over time replace those checks with bash sockets -- however it's
|
|
# still recommended to use the supplied binaries or cook your own, see
|
|
# https://github.com/drwetter/testssl.sh/blob/master/bin/Readme.md .
|
|
# Don't worry if feature X is not available you'll get a warning about
|
|
# this missing feature! The idea is if this script can't tell something
|
|
# for sure it speaks up so that you have clear picture.

(if pattern not a number: word match)
|

$PROG_NAME <options> URI ("$PROG_NAME URI" does everything except -E)
|
|
|
|
-e, --each-cipher checks each local cipher remotely
|
|
-E, --cipher-per-proto checks those per protocol
|
|
-f, --ciphers checks common cipher suites
|

-p, --protocols checks TLS/SSL protocols (including SPDY/HTTP2)
|
|
-y, --spdy, --npn checks for SPDY/NPN
|
|
-Y, --http2, --alpn checks for HTTP2/ALPN

-c, --client-simulation test client simulations, see which client negotiates with cipher and protocol

-s, --pfs, --fs, --nsa checks (perfect) forward secrecy settings

-4, --rc4, --appelbaum which RC4 ciphers are being offered?
|
|
|
|
special invocations:
|
|
-t, --starttls <protocol> does a default run against a STARTTLS enabled <protocol>
|
|
--xmpphost <to_domain> for STARTTLS enabled XMPP it supplies the XML stream to-'' domain -- sometimes needed
|
|
--mx <domain/host> tests MX records from high to low priority (STARTTLS, port 25)
|
|
--ip <ip> a) tests the supplied <ip> v4 or v6 address instead of resolving host(s) in URI
|
|
b) arg "one" means: just test the first DNS returns (useful for multiple IPs)
|
|
--file <fname> mass testing option: Reads command lines from <fname>, one line per instance.
|
|
Comments via # allowed, EOF signals end of <fname>. Implicitly turns on "--warnings batch"
|
|
|
|
partly mandatory parameters:
|
|
URI host|host:port|URL|URL:port (port 443 is assumed unless otherwise specified)
|
|
pattern an ignore case word pattern of cipher hexcode or any other string in the name, kx or bits
|
|
protocol is one of ftp,smtp,pop3,imap,xmpp,telnet,ldap (for the latter two you need e.g. the supplied openssl)
|
|
|
|
tuning options (can also be preset via environment variables):
|
|
--bugs enables the "-bugs" option of s_client, needed e.g. for some buggy F5s
|
|
--assuming-http if protocol check fails it assumes HTTP protocol and enforces HTTP checks
|
|
--ssl-native fallback to checks with OpenSSL where sockets are normally used
|
|
--openssl <PATH> use this openssl binary (default: look in \$PATH, \$RUN_DIR of $PROG_NAME
|
|
--proxy <host>:<port> connect via the specified HTTP proxy
|
|
-6 use also IPv6. Works only with supporting OpenSSL version and IPv6 connectivity
|
|
--sneaky leave less traces in target logs: user agent, referer
|
|
|
|
output options (can also be preset via environment variables):
|
|
--warnings <batch|off|false> "batch" doesn't wait for keypress, "off" or "false" skips connection warning
|
|
--quiet don't output the banner. By doing this you acknowledge usage terms normally appearing in the banner
|
|
--wide wide output for tests like RC4, BEAST. PFS also with hexcode, kx, strength, RFC name
|
|
--show-each for wide outputs: display all ciphers tested -- not only succeeded ones
|
|
--mapping <no-rfc> don't display the RFC Cipher Suite Name
|
|
--color <0|1|2> 0: no escape or other codes, 1: b/w escape codes, 2: color (default)
|
|
--colorblind swap green and blue in the output
|
|
--debug <0-6> 1: screen output normal but debug output in temp files. 2-6: see line ~120
|
|
|
|
file output options (can also be preset via environment variables):
|
|
--log, --logging logs stdout to <NODE-YYYYMMDD-HHMM.log> in current working directory
|
|
--logfile <file> logs stdout to <file/NODE-YYYYMMDD-HHMM.log> if file is a dir or to specified file
|
|
--json additional output of findings to JSON file <NODE-YYYYMMDD-HHMM.json> in cwd (experimental)
|
|
--jsonfile <file> additional output to JSON and output JSON to the specified file (experimental)
|
|
--csv additional output of findings to CSV file <NODE-YYYYMMDD-HHMM.csv> in cwd (experimental)
|
|
--csvfile <file> set output to CSV and output CSV to the specified file (experimental)
|
|
|
|
All options requiring a value can also be called with '=' e.g. testssl.sh -t=smtp --wide --openssl=/usr/bin/openssl <URI>.
|
|
|
|
<URI> is always the last parameter.
|
|
|
|
Need HTML output? Just pipe through "aha" (ANSI HTML Adapter: github.com/theZiz/aha) like
|
|
|
|
"$PROG_NAME <options> <URI> | aha >output.html"
