Usage

bin/check-ssl-anchor.rb

Check that a specific website is chained to a specific root certificate (Let's Encrypt for instance). Requires the openssl commandline tool to be available on the system.

./bin/check-ssl-anchor.rb -u example.com -a "i:/O=Digital Signature Trust Co./CN=DST Root CA X3"

bin/check-ssl-crl.rb

Checks a CRL has not or is not expiring by inspecting it's next update value.

You can check against a CRL file on disk:

./bin/check-ssl-crl -c 300 -w 600 -u /path/to/crl

or an online CRL:

./bin/check-ssl-crl -c 300 -w 600 -u http://www.website.com/file.crl

Critical and Warning thresholds are specified in minutes.

bin/check-ssl-qualys.rb

Checks the ssllabs qualysis api for grade of your server, this check can be quite long so it should not be scheduled with a low interval and will probably need to adjust the check timeout options per the check attributes spec based on my tests you should expect this to take around 3 minutes.

./bin/check-ssl-qualys.rb -d google.com

bin/check-ssl-root-issuer.rb

Check that a specific website is chained to a specific root certificate issuer. This is a pure Ruby implementation, does not require the openssl cmdline client tool to be installed.

./bin/check-ssl-root-issuer.rb -u example.com -a "CN=DST Root CA X3,O=Digital Signature Trust Co."

Installation

Installation and Setup

Testing

To run the testing suite, you'll need to have a working ruby environment, gem, and bundler installed. We use rake to run the rspec tests automatically.

bundle install
bundle update
bundle exec rake

Notes

bin/check-ssl-anchor.rb and bin/check-ssl-host.rb would be good to run in combination with each other to test that the chain is anchored to a specific certificate and each certificate in the chain is correctly signed.
