Intermediate Certification Authority (CA) Certificates

As of April 2006, all SSL certificates purchased through the VeriSign web site require the installation of an Intermediate CA certificate. The SSL certificates are signed by an Intermediate CA using a two-tier hierarchy (also known as trust chain) which enhances the security of your SSL certificates.

You can easily find and download the Intermediate CA Certificate for your product by clicking here.

Free Trial SSL Certificate

A special root Certificate Authority is used to digitally sign VeriSign Trial SSL Certificates:

You need to:

  2. Install the Secure Site Trial Intermediate CA on each Web server used for testing.  
    Note: Customers using Microsoft IIS 5.0 or 6.0 servers can skip this step.
