Importing the certificate in Oracle API gateway

We received the self signed certificate from our partner and while importing in API gateway we received the Error

The simple way to resolve this issue  is to use Windows "Certificate Export Wizard" and choose copy to file option .
 In Export File format export screen choose "DER Encoded binary X.509 (.CER).

 Use this exported .cer file to successfully import the certificate.
