Creating a .pem File for SSL Certificate

Some applications require you to provide SSL in .pem file format. This can be easily created your own by combining SSL cerifcate provided by your SSL provider.

Open a text file, paste content of your SSL certificate in following order.

  1. Private key – yourdomainname.key
  2. The Primary Certificate – yourdomainname.crt
  3. The Intermediate Certificate – COMODORSADomainValidationSecureServerCA.crt
  4. The Root Certificate – COMODORSAAddTrustCA.crt

On a Cpanel server, i get the Cert file location from httpd.conf, then used following command to create .pem file

cat /var/cpanel/ssl/installed/certs/ehcp1_yboby_cf_c6de0_47a9f_1512431999_401807c229ea59bda3e602f2bcfff4cc.crt > ~/ssl-cert.pem
echo >> ~/ssl-cert.pem
cat /var/cpanel/ssl/installed/cabundles/cPanel_Inc__681917bfb43af6b642178607e0b36ccc_1747526399.cabundle >> ~/ssl-cert.pem
echo >> ~/ssl-cert.pem

The SSL paths here are just an example, you have to use your domain’s certificate paths. If you have cert from the provider, just cut and paste.
