.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.

A certificate.crt and privateKey.key can be extracted from your Personal Information Exchange file (certificate.pfx) using OpenSSL. Follow this article to create a certificate.crt and privateKey.key files from a certificate.pfx file.

This article contains multiple sets of instructions that walk through various .pem file creation scenarios.

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-----
   (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.

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-----
   (Your Intermediate certificate: DigiCertCA.crt)
   -----END CERTIFICATE-----

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

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 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-----
   (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.
