Edit script to add certificate to keycert (Pylutron)

I’m running openHAB 3.4.2 on a Mac running OSX High Sierra with Java 8 (build 1.8.0_333-b02).

In order to add the Caseta Smart Hub PRO to openHab, I’ve followed these instructions page and generated the following files.

I need help understanding this script that adds these files into keycert so that I can edit the script with the correct file names?

Also would renaming the .crt and key files generated by pylutron (before adding them to keycert) cause anything to go Kaput?

openssl pkcs12 -export -in caseta.crt -inkey caseta.key -out caseta.p12 -name caseta

keytool -importkeystore -destkeystore lutron.keystore -srckeystore caseta.p12 -srcstoretype PKCS12 -srcstorepass secret -alias caseta

keytool -importcert -file caseta-bridge.crt -keystore lutron.keystore -alias caseta-bridge

Thanks in advance!
