问题
I've only the .cer file now i want to convert it to .pfx file. But when i tried to convert via openssl it is asking for private key file? Is it necessary to have a private key file to generate a .pfx file? if not then could you please suggest the open ssl command to accomplish this. Thanks Sushma.
