SSH private key file format must be PEM (for example, use ssh-keygen -m PEM to convert the OpenSSH key into the PEM format) Create an RSA key. Amazon EC2 does not accept DSA keys. Jul 09, 2019  You can generate a new private key and CSR. And saved as files with “.key” or “.pem” extensions on the server. But no specific extensions are mandatory for text files in Linux, so the key file may have any name and extension, or no extension at all.

.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.

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.

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-----
   (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

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.
