.pem SSL Creation Instructions
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
- Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt), Root (TrustedRoot.crt), and Primary Certificates (your_domain_name.crt).
-
Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:
- The Primary Certificate - your_domain_name.crt
- The Intermediate Certificate - DigiCertCA.crt
- 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
-
(Your 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
- Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).
-
Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:
- The Primary Certificate - your_domain_name.crt
- 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
-
(Your 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
- Log into your DigiCert Management Console and download your Intermediate (DigiCertCA.crt) and Primary Certificates (your_domain_name.crt).
-
Open a text editor (such as wordpad) and paste the entire body of each certificate into one text file in the following order:
- The Private Key - your_domain_name.key
- The Primary Certificate - your_domain_name.crt
- The Intermediate Certificate - DigiCertCA.crt
- 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
-
(Your Private Key: your_domain_name.key)
-END RSA PRIVATE KEY
-
-BEGIN CERTIFICATE
-
(Your Primary SSL certificate: your_domain_name.crt)
-END CERTIFICATE
-
-BEGIN CERTIFICATE
-
(Your 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.
