How to convert a cert from DER format to PEM format and vice versa?

Resolution:

To convert a binary format cert/key (DER) to a PEM format cert/key or vice versa, the tools from openssl (www.openssl.org) can be used.

Here are the commands:

1. To convert a cert from DER format to PEM format:

openssl x509 -in input.cer -inform DER -out output.cer -outform PEM

2. To convert a cert from PEM format to DER format:

openssl x509 -in input.cer -inform PEM -out output.cer -outform DER

3. To convert a private key from DER format to PEM format:

openssl rsa -in inkey.cer -inform DER -out outkey.cer -outform PEM

4. To convert a private key from PEM format to DER format:

openssl rsa -in inkey.cer -inform PEM -out outkey.cer -outform DER
