# Seriously! The threat is you run this code on your computer and input could be /
# is being supplied via untrusted sources.
# 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 is 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.

"$PROG_NAME <options> URI", where <options> is:
-t, --starttls <protocol> does a default run against a STARTTLS enabled <protocol,
protocol is <ftp|smtp|pop3|imap|xmpp|telnet|ldap|postgres> (latter three require supplied openssl)
--xmpphost <to_domain> for STARTTLS enabled XMPP it supplies the XML stream to-'' domain -- sometimes needed
--mx <domain/host> tests MX records from high to low priority (STARTTLS, port 25)
--file <fname> mass testing option: Reads command lines from <fname>, one line per instance.
Comments via # allowed, EOF signals end of <fname>. Implicitly turns on "--warnings batch"
single check as <options> ("$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
-S, --server-defaults displays the server's default picks and certificate info
-P, --server-preference displays the server's picks: protocol+cipher
-x, --single-cipher <pattern> tests matched <pattern> of ciphers
(if <pattern> not a number: word match)
-c, --client-simulation test client simulations, see which client negotiates with cipher and protocol
-H, --header, --headers tests HSTS, HPKP, server/app banner, security headers, cookie, reverse proxy, IPv4 address
-U, --vulnerable tests all (of the following) vulnerabilities (if applicable)
-B, --heartbleed tests for heartbleed vulnerability
-I, --ccs, --ccs-injection tests for CCS injection vulnerability
-R, --renegotiation tests for renegotiation vulnerabilities
-C, --compression, --crime tests for CRIME vulnerability
-T, --breach tests for BREACH vulnerability
-O, --poodle tests for POODLE (SSL) vulnerability
-Z, --tls-fallback checks TLS_FALLBACK_SCSV mitigation
-F, --freak tests for FREAK vulnerability
-A, --beast tests for BEAST vulnerability
-J, --logjam tests for LOGJAM vulnerability
-D, --drown tests for DROWN vulnerability
-s, --pfs, --fs, --nsa checks (perfect) forward secrecy settings
-4, --rc4, --appelbaum which RC4 ciphers are being offered?
tuning / connect options (most also can be preset via environment variables):
--fast omits some checks: using openssl for all ciphers (-e), show only first
preferred cipher
--bugs enables the "-bugs" option of s_client, needed e.g. for some buggy F5s
--assume-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
--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)
-n, --nodns do not try any DNS lookup
--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
--openssl-timeout <seconds> useful to avoid hangers. <seconds> to wait before openssl connect will be terminated
--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 keeps debug output in /tmp/. 2-6: see "grep -A 5 '^DEBUG=' testssl.sh"
file output options (can also be preset via environment variables):
--log, --logging logs stdout to <NODE-YYYYMMDD-HHMM.log> in current working directory
--logfile <logfile> logs stdout to <file/NODE-YYYYMMDD-HHMM.log> if file is a dir or to specified log file
--json additional output of findings to flat JSON file <NODE-YYYYMMDD-HHMM.json> in cwd
--jsonfile <jsonfile> additional output to the specified flat JSON file
--json-pretty additional pretty structured output of findings to JSON file <NODE-YYYYMMDD-HHMM.json> in cwd
--jsonfile-pretty <jsonfile> additional pretty structured output as JSON to the specified file
--csv additional output of findings to CSV file <NODE-YYYYMMDD-HHMM.csv> in cwd
--csvfile <csvfile> additional output as CSV to the specified file
--hints additional hints to findings
--severity <severity> severities with lower level will be filtered for CSV+JSON, possible values <LOW|MEDIUM|HIGH|CRITICAL>
--append if <csvfile> or <jsonfile> exists rather append then overwrite
Options requiring a value can also be called with '=' e.g. testssl.sh -t=smtp --wide --openssl=/usr/bin/openssl <URI>.
URI always needs to be 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" or use -log* and convert later
