Thank you JJK and everyone!! Jan, that was it! Never thought to check the key size. Just too close to it I guess. I could handle the 2,048 bit keys but set a fixed maximum register size of 4,096 bits. Well, it needs 6,144 bits to do the 3,072 bit math. My bad as they say. I do have a ToDo in the

Jan, Use Wireshark all of the time. In fact I've used it since before it was Wireshark. But now... I can't remember what it was called before. Great tool. You, though, may have hit on something in pointing out the 3072 bit key. I will check on that. It was a design decision in developing this

Sorry, By "If OpenSSL fails to validate this particular digital signature that would be the case." I meant to question whether or not OpenSSL is in fact doing the validation? In the case that the signature is being ignored then clients wouldn't complain. They wouldn't notice. Bruce On 6/25/20

Yeah. I doubt it is an OpenSSL issue directly as Apache might be feeding the wrong key. Just need confirmation that there isn't a default key configuration setting for OpenSSL that might be taking precedence for who knows why. I can connect successfully with the browser so I cannot rule out that

Has anyone thought about this question? The site is https://jnior.com if anyone wants to hit it. For me the digital signature in the server_key_exchange does not verify. Is there a site diagnostic that might report on this? I suspect that we have not fully configured the change in certificates.
