Use the openssl command to convert between formats as follows:

To convert a certificate from PEM to DER: x509 \u2013in input.crt \u2013inform PEM \u2013out output.crt \u2013outform DER

To convert a certificate from DER to PEM: x509 \u2013in input.crt \u2013inform DER \u2013out output.crt \u2013outform PEM

To convert a key from PEM to DER: rsa \u2013in input.key \u2013inform PEM \u2013out output.key \u2013outform DER

To convert a key from DER to PEM: rsa \u2013in input.key \u2013inform DER \u2013out output.key \u2013outform PEM
