Converting a certificate from the DER encoding to the PEM encoding

After processing the Certificate Signing Request, the certification authority may issue a signed certificate in the X.509 format (file with the CER or CRT extension).

The X.509 certificate file can be provided in two encodings:

If the certificate is provided in the DER encoding, you must convert it to the PEM encoding. You can use the openssl utility to convert the certificate.

To convert a certificate from the DER encoding to the PEM encoding, use the following command:

openssl x509 -in source.cer -inform DER -out cert.pem

You can use the obtained cert.pem file to replace the web interface certificate.
