SSL .pem files (concatenated certificate container files), are frequently required for certificate installations when multiple certificates are being imported as one file.

 

Creating a .pem with the Entire SSL Certificate Trust Chain

 

1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt), Root (TrustedRoot.crt), and Primary Certificates (your_domain_name.crt).

2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

  1. The Primary Certificate - your_domain_name.crt
  2. The Intermediate Certificate - DigiCertCA.crt
  3. The Root Certificate - TrustedRoot.crt

Make sure to include the beginning and end tags on each certificate. The result should look like this:

-BEGIN CERTIFICATE
-
(Your Primary SSL Certificate: your_domain_name.crt)
END CERTIFICATE
BEGIN CERTIFICATE
(You Intermediate Certificate: DigiCertCA.crt)
END CERTIFICATE
BEGIN CERTIFICATE
(Your Root Certificate: TrustedRoot.crt)
END CERTIFICATE

Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

 

Creating a .pem with the Server and Intermediate Certificates

 

1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).

2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

  1. The Primary Certificate - your_domain_name.crt
  2. The Intermediate Certificate - DigiCertCA.crt

Make sure to include the beginning and end tags on each certificate. The result should look like this:

BEGIN CERTIFICATE
(Your Primary SSL Certificate: your_domain_name.crt)
END CERTIFICATE
BEGIN CERTIFICATE
(You Intermediate Certificate: DigiCertCA.crt)
END CERTIFICATE

Save the combined file as your_domain_name.pem. The .pem file is now ready to use.

 

Creating a .pem with the Private Key and Entire Trust Chain

 

1. Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).

2. Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:

  1. he Private Key - your_domain_name.key
  2. The Primary Certificate - your_domain_name.crt
  3. The Intermediate Certificate - DigiCertCA.crt
  4. The Root Certificate - TrustedRoot.crt

Make sure to include the beginning and end tags on each certificate. The result should look like this:

BEGIN RSA PRIVATE KEY
(You Private Key: you_domain_name.key)
END RSA PRIVATE KEY
BEGIN CERTIFICATE
(Your Primary SSL Certificate: your_domain_name.crt)
END CERTIFICATE
BEGIN CERTIFICATE
(You Intermediate Certificate: DigiCertCA.crt)
END CERTIFICATE
BEGIN CERTIFICATE
(Your Root Certificate: TrustedRoot.crt)
END CERTIFICATE

Save the combined file as your_domain_name.pem. The .pem file is now ready to use.
