I need a certificate from a well-known CA in pkcs12 format. That standard requires that the private key be bundled in the certificate file. I know I could use let’s encrypt however, a downstream provider has a limitation that the certificate expiry must be longer than the 90 days provided by let’s encrypt.
I am trying to understand if Cloudflare could provide this. As far as I can tell from the documentation, that does not seem possible.
Is there anyone who happens to know if that is the case? If not, do you have suggestions (other than Let’s Encrypt) for a reputable CA where I can get a certificate for my domain?
