How do I convert my PEM certificate to a DER certificate format?

Article Number: 42657

Applicable to:  Specific vendors and versions of server software or browser software may prefer the DER encoded format over Base64 (PEM)

Entrust Datacard Cloud Services issues Base64 encoded (PEM) server certificates

Normally, you can use OpenSSL or Internet Explorer on a Windows system.

OpenSSL conversion steps:

openssl x509 -in cert.pem -out cert.der -outform DER 

(where cert.pem is your server cert and cert.der is your new file name)

 

Internet Explorer conversion steps:

1. Download the standard format certificate and save it into a text file with the complete "-----BEGIN CERTIFICATE-----", "-----END CERTIFICATE-----" lines, and no other characters included.

2. Import the certificate file into Internet Explorer:

Tools > Internet Options > Content > Certificates > Import > Select certificate file.

The certificate should then be stored in your 'Other People' certificate store (you can view it under 'Other People').

3. Select the certificate > Export > select "DER ENCODED Binary X.509 (.cer)" > Choose a file name and save.


You now have a DER encoded certificate file for your use.
