Comodo Root & Intermediate Certificate: A Detailed Explanation<\/strong><\/h2>\n

Certificate Authorities<\/strong> (COMODO CA<\/strong>) use root and intermediate certificates that need to be installed along with the site\u2019s domain certificate on the web browser. This enables web browsers and mobile phones to connect seamlessly to the secured domain. If you don\u2019t download and install a root and intermediate certificate, you might receive an error from your browser.<\/p>\n

Before focusing on the root and intermediate certificates, you should get yourself a Comodo SSL Certificate. Depending on your needs, it will be worth noting the difference between a Wildcard & Multi-Domain (SAN) SSL Certificate<\/a>. For instance, if you\u2019re a big organization<\/a> and need to secure an unlimited number of subdomains regularly, you might want to go for Wildcard SSL Certificates.<\/p>\n

During the SSL installation process, you might be asked to install an intermediate or root certificate. In this article, we\u2019ll give you an overview of Comodo Root Certificate<\/strong> and Comodo Intermediate Certificate<\/strong> and how you can download and install them.<\/p>\n

Comodo Root Certificate<\/h3>\n

Comodo Root Certificates are Comodo\u2019s issuing roots. As such, all other Comodo SSL certificates are issued by it and its descendants and are chained back to it. It\u2019s important because a Comodo SSL certificate can only be trusted if it\u2019s chained to a root either directly or through intermediaries. Comodo Root CA<\/strong> Certificates are some of the most trusted certificates in the world with over 100 million websites secured. All root certificates have a long lifespan, generally going over 20 years.<\/p>\n

Steps to Install Comodo Root Certificate:<\/h2>\n

It\u2019s pretty uncommon to install a Comodo root certificate directly. Comodo is a universally trusted Certificate Authority and the Comodo Root Certificate is already a part of most major root programs. If you need to download the root for any reason it\u2019s available on Comodo\u2019s website.<\/p>\n

Comodo Intermediate Certificate<\/h2>\n

A Comodo Intermediate Certificate can be a part of the certificate chain which leads back to the trusted Comodo Root Certificate. Most Certificate Authorities don\u2019t issue directly from the Comodo RSA Certification Authority root because it\u2019s incredibly valuable and if it\u2019s compromised, the fallout would be severe. As such, a Comodo Intermediate Certificate is used for two primary purposes:<\/p>\n
