Reviewing the files received from VikingCloud™

When your certificate is issued, VikingCloud will email a zip file that contains your certificate in the following formats:

• .pem - This file contains a Base64 encoded ASCII concatenation of your certificate and the intermediate certificate that your certificate was issued from. It contains the "-----BEGIN CERTIFICATE-----" and the "-----END CERTIFICATE-----" lines around each certificate.
• .cer - This file contains a Base64 encoded ASCII format of only your certificate with the "-----BEGIN CERTIFICATE-----" and the "-----END CERTIFICATE-----" lines around it.
• .p7b - This file contains a Base64 encoded ASCII representation of your certificate and the intermediate certificate that your certificate was issued from. It contains the "-----BEGIN PKCS7-----" and the "-----END PKCS7-----" lines around the certificates.
• .der - This file contains a binary representation of your certificate.
• chain.cer - This file contains a Base64 encoded ASCII representation of the intermediate certificate.

You can also login to Control Center and view your issued certificates. When you click on a certificate and scroll to the bottom of the page, you can download the certificate zip folder.

You will need the file yourDomain.cer for this installation. This file is your actual certificate.

Install your VikingCloud™ Digital Server Certificate

Click the certificate's name on the Certificates page and enter the path to the file on your local machine or network in order to upload the certificate.

When you upload the certificate from the certificate authority, the existing certificate is overwritten. You can also upload an intermediate certificate related to your certificate. This is the certificate in the chain.cer file.
