[openssl-users] Need help encrypting my ca.key

Thanks for the response.  First I am running this on Windows 7.   Questions

1. How can I determine what key format my ca.key is in?
2. You say there are multiple key formats for the same key, but for my peace of mind I would like to get the same key format that I originally had.  How can I do this?
