What are these links in my 'Enrollment Successful' email used for?

Comodo Certificate Manager offers its customers several different certificate formats for use with the various server software platforms available on the market today.

We presently offer:


  • PKCS#7 Base64 encoded
  • PKCS#7 Bin encoded

PKCS#7 is commonly used with IIS 5.x and later.
This file contains the: Root, Intermediate(s) and your certificate; all rolled into a single file.

X509 Base64 is also commonly referred/known as PEM format.

    • X509, Base64 encoded

This file typically includes (in order): Root, Intermediate(s) and your certificate.

  • X509 Intermediates/root only, Base64 encoded

This file includes only the Root and Intermediate CA certificates (in order) for your domain/entity certificate.

  • X509 Certificate only, Base64 encoded

This file contains only your domain/entity certificate and is commonly used with Apache-based systems (Apache Directive: SSLCertificateFile), Tomcat and Oracle Wallet Manager.

  • X509 Intermediates/root only (Reverse), Base64 encoded

This file contains only the Intermediate(s) and Root CA certificates (in reverse order) and is commonly used with Apache-based systems (Apache2 Directive: SSLCertificateChainfile). This file is also known as a 'CA Bundle' or 'Certificate Chain File'.

Note: Some software will want the certificates in this file in its own separate file. If this is needed, simply use a text-editor and extract them accordingly. (e.g. Tomcat when using 'keytool', Oracle Wallet Manager, IKEYMAN)
