.pem SSL Creation Instructions

  • They can be thought of as a layered container of chained certificates. A.pem file is a container format that may just include the public certificate or the entire certificate chain (private key, public key, root certificates): Private Key; Server Certificate (crt, puplic key) (optional) Intermediate CA and/or bundles if signed by a 3rd party.
  • I saved an rsa private key in a binary file (in PEM format), among other data. I knew its offset, but not its size. When I needed to load, I generated a temporary key, and used its size to load the.

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

Alright, now let’s get back to the terminal and run: openssl req -x509 Then -newkey rsa:4096 This option basically tells openssl to create both a new private key with RSA 4096-bit key, and its certificate request at the same time. As we’re using -x509 option, it will output.

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.
