@passmarked/ssl1.0.10 • Public • Published
Passmarked is a suite of tests that can be run against any page/website to identify issues with parity to most online tools in one package.
The Terminal Client is intended for use by developers to integrate into their workflow/CI servers but also integrate into their own application that might need to test websites and provide realtime feedback.
All of the checks on Passmarked can be voted on importance and are open-sourced, to encourage community involvement in fixing and adding new rules. We are building the living Web Standard and love any contributions.
The module firstly does a resolve on the DNS address (or just directly uses the single IP), and then runs the following tests again each of the resolved IP's:
The rules checked in this module are:
- anonymous - Server has ciphers ciphers enabled
- connect - Returned when the connection to the server over TLS/SSL could not be opened
- cipher - Server has a known weak cipher enabled, any of the following ciphers will raise this issue: NULL, EXPORT, LOW, 3DES, MD5, RSK or RC4
- compression - Server has TLS compression enabled which also leads to a vulnerability for the OpenSSL CRIME attack
- crime - Vulnerability to the CRIME attack was found as TLS Compression was enabled
- expire - The certificate is shorter than a month away from expiring.
- expired - The certificate presented by the server has expired and is not valid anymore
- freak - The server has the EXPORT cipher enabled which leads to a vulnerability for the FREAK attack.
- form.internal - An unsecurred internal form action from the HTTPS page will cause a browser to show a unsecure message
- form.external - An unsecurred external form action from the HTTPS page will cause a browser to show a unsecure message
- field.creditcard - The page will be shown as unsecure due to it not being over HTTPS but including a field identified as a credit card field
- field.password - The page will be shown as unsecure due to it not being over HTTPS but including a password field
- heartbleed - Vulnerability to the HeartBleed attack was found
- host - The certificate presented by the server did not have the host requested featured, leading to a hostname mismatch error.
- missing - The server did not supply a certificate, this normally indicates that no certificate was configured although SSL is being offered.
- poodle - Vulnerability to the POODLE attack was found
- enabled - If the given url is not HTTPS, the issue is raised to recommend switching to SSL for the security of useres.
- renegotiation.client - Client Renegotiation is enabled but was expecting it to be disabled to lock the server down correctly.
- signature - The returned certificate makes use of SHA1 hashing which is obsolete after 2016, browsers will be giving out warnings from October 2016 about these certificates that are signed with SHA1.
- ssl2 - SSLv2 was detected on the server, this should be disabled as fast as possible.
- ssl3 - SSLv3 was detected on the server, this should be disabled as fast as possible.
- sni - SNI is not enabled, meaning the server can only serve a single website.
- oscp - OSCP was not detected.
- oscp.config - OSCP is enabled but the config could not be determined by the check
- oscp.cert - The OSCP certificate status returned by the server was not successfull.
- tls1 - TLSv1 was not detected, should be enabled to ensure compatibility with the largest secured user base.
- tls1.1 - TLSv1.1 was not detected, should be enabled to ensure compatibility with the largest secured user base.
- tls1.2 - TLSv1.2 was not detected, should be enabled to ensure compatibility with the largest secured user base.
- verify - Verification of the certificate with common known root certificated failed, most probably could indicate a privately signed key.
- chain.missing - Missing intermediate certificates detected from the chain returned by the server, the daa returned contains the full chain as expected with all the needed certificates.
- chain.signature - Certificates that were expected in the chain contains certificates using a weaker signature hash.
- chain.trusted - The certificate trusted returned from the server contains a root certificate, which is according to how PKI is designed will be wasting a few bytes for every request. These should be removed.
- chain.order - Order of the certifiate chain provided is wrong
- chain.verify - Unable to verify a intermediate certificate or if any of the certificates have been revoked.
- chain.unexpected - Unable to verify a intermediate certificate or if any of the certificates have been revoked.
- compatibility - Returned if the configured settings on the server do not (at least) match the "Intermediate" setting from the Mozilla SSL recommendations. The Intermediate level will provide the most security (with a few draw backs) it can to support the biggest list of available clients all the way back to
Firefox 1, Chrome 1, IE 7, Opera 5, Safari 1, Windows XP IE8, Android 2.3, Java 7.
npm install -g passmarkedpassmarked --filter=ssl example.com
The hosted version allows free runs from our homepage and the option to register a site to check in its entirety. Using the Passmarked npm module (or directly via the API) integrations are also possible to get running reports with all the rules in a matter of seconds.
CA Certs are loaded on startup, and the .crt used to read in the certificates can be configured using
CA_CERTS, the default is
All rules can be run locally using our main integration library. This requires installing the package and any dependencies that the code might have such as a specific version of OpenSSL, see #dependencies
passmarked is installed:
npm install passmarkednpm install @passmarked/ssl
After which the rules will be runnable using promises:
Alternatively, callbacks are also available:
The module expects a updated version of OpenSSL, at the time of writing
openssl-1.0.2h. The module expects the newest compiled excutable to present at
# install our essentials to build opensslapt-get install -y build-essential# upgrade to a much newer and specific version of sslwget -O /tmp/openssl-1.0.2h.tar.gz https://www.openssl.org/source/openssl-1.0.2h.tar.gzcd /tmp/ && tar -xf /tmp/openssl-1.0.2h.tar.gzrm /tmp/openssl-1.0.2h.tar.gzcd /tmp/openssl-1.0.2h && ./configcd /tmp/openssl-1.0.2h && make dependcd /tmp/openssl-1.0.2h && makecd /tmp/openssl-1.0.2h && make installrm -R /tmp/openssl-1.0.2h
We do also host a binary build for x86 Ubuntu over at package.passmarked.com/openssl/builds/openssl-x86-1.0.2h.bin that is mostly used for quick testing but would work if you require a quick way to get started.
The module also expects to see
coreutils present in some form, this defaults to
gtimeout on MacOS which can be installed using:
brew install coreutils
Also be sure to install the CA certificates and keep it updated, as these are used to check if a certificate is valid:
apt-get install -y ca-certificates
Rules also include a

Pull requests have a prerequisite of passing tests. If your contribution is accepted, it will be merged into
develop (and then
master after staging tests by the team) which will then be deployed live to passmarked.com and on NPM for everyone to download and test.
