A few months ago a colleague who left generated a CA certificate from GoDaddy. I am not sure the exact steps he took but currently we would like to install the CA certificate on a server to fully comply with EFRIS regulations which mandate that clients should transition from self-signed certificates to CA certificates within 3 months of go-live.
Somehow he was able to generate the .p12 private certificate. I suspect he used a desktop application called Keystore Explorer but he set a password on the certificate so I can't use it because I don't know it.
I was able to access the godaddy website and downloaded the original certificate files provided by GoDaddy CA. They are a PEM file, a CRT file and two other files called bundle files.
My wish is to generate the relevant .p12 or .pfx or .jks private certificate out of these PEM and CRT files but I don't know how. I think the public certificate will still be the .crt file.
When I tried to use Keystore Explorer to generate the private key PKCS file, I was able to generate it but it did not have the private key in it and the server gave an error telling me that the private key is missing from the .pfx file. I am not sure what this private key is supposed to be. Is it something I should already have?
I have tried to google for ways to convert a PEM file to a PKCS file but the guides have been so far unclear. For now I am reading this SSL stackexchange post to find out how SSL works. Any help will be greatly appreciated.
