How to use .p12 user certificate from Mumble?

Created by: nickehallgren

I would like to use a p12 certificate to login to a my local server (self-signed) and be recognized as that user (registered) and moved to the right channel without using a password. I read somewhere that the p12 cert should be converted to a pem (as below)? If that is the case how do I use it?

openssl pkcs12 -in path.p12 -out newfile.crt.pem -clcerts -nokeys
openssl pkcs12 -in path.p12 -out newfile.key.pem -nocerts -nodes
