∟Certificate X.509 Standard and DER/PEM Formats

1. Save the combined file as yourdomainname.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 (yourdomainname.crt).
2. Just as a.crt file is in.pem format, a.key file is also stored in.pem format. Assuming that the cert is the only thing in the.crt file (there may be root certs in there), you can just change the name to.pem. The same goes for a.key file. Which means of course that you can rename the.pem file to.key. Which makes gtrig's answer the.

∟'OpenSSL' Generating Certificates in DER and PEM

This section provides a tutorial example on how to generate certificates in DER and PEM formats using 'OpenSSL'.

After tested how 'keytool' can be used to export certificates in DER and PEM formats, I decided to try with 'OpenSSL' to see if it can generate certificates in DER and PEM formats or not. What I did was to:

Jul 17, 2017  How to Generate pem file to ssh the server without Password in Linux. July 17, 2017 July 18. To generate an RSA key pair for version 2 of the SSH protocol, follow these steps. One thought on “ How to Generate pem file to ssh the server without Password in Linux ”. How to Generate a Self-Signed Certificate and Private Key using OpenSSL Generating a private key and self-signed certificate can be accomplished in a few simple steps using OpenSSL. We provide here detailed instructions on how to create a private key and self-signed certificate valid for 365 days.

• Run 'openssl genrsa' to generate a RSA key pair.
• Run 'openssl req -new -x509' to generate a self-signed certificate and stored it in PEM format.
• Run 'openssl x509' to convert the certificate from PEM encoding to DER format.

The test session was recorded below:

Now I got one certificate generated by 'OpenSSL' and stored in two files: openssl_crt.der and openssl_crt.pem. How can I verify that they are really using DER and PEM formats? I used 'keytool' to try to view them as described in the next section.
