PSM:EV Testing Easy Version

This page is for Certificate Authorities (CAs) who request to have a root certificate enabled for Extended Validation (EV) treatment, and need to test that their CA hierarchy is ready for EV treatment.

To request that your root certificate be included in NSS and enabled for EV treatment, start with the Mozilla CA Certificate Policy and the How to Apply guidelines.

This page explains how you can test that your certificates and OCSP infrastructure are working correctly according to the expectations of Mozilla, Firefox, and the NSS library; and conforms to the SSL protocol specifications (as interpreted by Mozilla/NSS software.)

EV-Readiness Check

To test your CA hierarchy to see if it is ready to request EV treatment:

1. Browse to https://tls-observatory.services.mozilla.com/static/ev-checker.html
2. Enter the URL to the test website for the EV certificate (do not include the https:// in front of the URL)
   • Example: observatory.mozilla.org
3. Enter the EV Policy OID
   • Example: 2.23.140.1.2.2
4. Enter the PEM data for the root certificate
   • Begin with: -----BEGIN CERTIFICATE-----
   • End with: -----END CERTIFICATE-----
   • Example PEM Data
   • Help with getting PEM
5. Click on "Submit"

Success

A successful result says: "ev-checker exited successfully: Success!"

Test Failure?

The purpose of this test is to make sure you have set up EV according to the EV Guidelines, so make sure you have not taken short-cuts like issuing the test cert directly from the root.

• The EV test only uses the root certificate it is given. So, if you are using an intermediate certificate that has been cross-signed with another root certificate, you may see different results when browsing to the site in Firefox, as opposed to the results provided by the EV Test.
• OCSP must work without error for the intermediate certificates. For more information see: https://wiki.mozilla.org/CA:EV_Revocation_Checking#Requirements
• The EV Policy OID in the end-entity and intermediate certificates must match the EV Policy OID that you enter. (Note: the intermediate cert can use the anyPolicy oid rather than the EV policy oid.)
  • SEC_ERROR_POLICY_VALIDATION_FAILED error may mean that the intermediate certificate being sent by the server doesn't have a certificate policies extension, or has an incorrect policy OID.
• If the test website cannot be reached by the server hosting the tool, check to see if you have a firewall preventing access from Amazon EC2 instances. If you are unable to create a test website that can be reached by the server hosting the tool, then you can download a copy of the source code for the tool, compile it, and run it on your own server.
  • If you are unable to provide a test website that can be reached by the server hosting the tool, then please also attach the text output from the test to the bug (in addition to the screen shot showing successful completion of the test).
• Still failing? Try testing with https://certificate.revocationcheck.com/ because frequently resolving the errors listed on that page will resolve problems with EV testing.

Running the test locally

The following instructions may help you compile and run EV-Checker on Mac OS X.

• One-time setup if needed, to get necessary developer tools
  • In Terminal window:
    • curl https://hg.mozilla.org/mozilla-central/raw-file/default/python/mozboot/bin/bootstrap.py > bootstrap.py && python bootstrap.py
    • Reference: https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Build_Instructions/Mac_OS_X_Prerequisites
  • Other things you might need to install:
    • brew install gnutls
    • brew install nodejs
    • brew install npm
• To get the latest version of ev-checker:
  • git clone https://github.com/mozkeeler/ev-checker
  • cd ev-checker
  • make clean
  • make
• To run EV Checker:
  • In Terminal window cd to the ev-checker folder and type: node server.js
  • In Firefox browser: http://localhost:8000/
  • Note: only one copy of the server may be running at a time. If you get an EADDRINUSE error, then in a terminal window type:
    • lsof -iTCP -sTCP:listen
    • Look for any lines starting with "node"

About the Testing Tool

The code for the Testing Tool is here: https://github.com/mozkeeler/ev-checker

The Testing Tool...

• Runs a program on a remote computer rather than the user's browser, so it should work with any browser/version.

• Does not interact with the user's profile, so the user does not need to import the root certificate in order to run the tool. The web server must serve up the intermediate cert(s) along with the end-entity cert.

• Runs on an Amazon EC2 instance, so your test website must be accessible from Amazon EC2 instances.
