My SSL certificate expired. I received a new one from SSLs.com. They also sent a private key. I imported the .p7b, which installs the entire trust chain. Importing the supplied private key does not work.
1. I created self-signed private keys for test and prod. I exported the public keys and sent it to the vendor. We get a handshake error. I applied my self-signed private keys to my Partner (me).
2. What process am I not doing correctly?
its not fully clear to us what happens there. Anyway the support of the CA should know everything about their trusting process - did you contact them?
