testssl.sh – Test SSL Security Including Ciphers, Protocols & Detect Flaws

userid@somehost:~ % testssl.sh

testssl.sh <options>

     h, help                    what you‘re looking at

     -b, –banner                  displays banner + version of testssl.sh

     -v, –version                 same as previous

     -V, –local                   pretty print all local ciphers

     -V, –local <pattern>         which local ciphers with <pattern> are available?

                                   (if pattern not a number: word match)

testssl.sh <options> URI    (“testssl.sh 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, serverpreference       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 vulnerabilities

     -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?

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 the STARTTLS protocols 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

     –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 testssl.sh)

     –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 <06>                 1: screen output normal but keeps debug output in /tmp/.  26: see “grep -A 5 ‘^DEBUG=’ testssl.sh”

file output options (can also be preset via environment variables):

     log, logging              logs stdout to <NODEYYYYMMDDHHMM.log> in current working directory

     logfile <logfile>           logs stdout to <file/NODEYYYYMMDDHHMM.log> if file is a dir or to specified log file

     json                        additional output of findings to JSON file <NODEYYYYMMDDHHMM.json> in cwd

     jsonfile <jsonfile>         additional output to JSON and output JSON to the specified file

     csv                         additional output of findings to CSV file  <NODEYYYYMMDDHHMM.csv> in cwd

     csvfile <csvfile>           set output to CSV and output CSV to the specified file

     append                      if <csvfile> or <jsonfile> exists rather append then overwrite

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

   “testssl.sh <options> <URI> | aha >output.html”
