Molly Brown Certificate Zone Help

I was able to solve my problem, although I'm still not sure what the issue
I stumbled across solderpunk's gemcert
<https://tildegit.org/solderpunk/gemcert> program for creating
certificates. His program provides server and client key pairs. As part of
the client key creation process, it automatically outputs a certificate
fingerprint with SHA256 encoding.
With this I did the following:
1. Reinstall server certificates issued by gemcert
2. Add client key and certificate to Kristall issued by gemcert
3. Added the hash provided by gemcert from creating client certificates to
the CertficiateZone are of the Molly Brown configuration file.
4. Restart Molly Brown
I can now browse the restricted area using the client certificate, but I'm
still not sure why this worked and creating one through OpenSSL did not
work. The only difference I could see is that gemcert creates ECDSA
certificates instead of the RSA ones I tried previously.
If anyone has any insights, I'd love to understand why this was successful.
Unfortunately the only thing I learned through all this is to use gemcert
for client certificates and I have no idea why.
