[routeconverter]

If I run RouteConverter for macOS, it don't works again...
BUT, if in run Linux version of RC under macOS (with java -jar RouteConverterLinux.jar), it works !

Great!

So, I supposed is it because the cacerts used by RouteConverterMacOpenSource.app is in app, not in /Library/... and yes, it is.

You're right. The old applauncher approach didn't work with macOS 10.14 and later, so I've switch to a new one based on jpackage which means the RouteConverterMacOpenSource.app contains a prerelease of JRE 14.

I imported the Certigna root CA certificate in the cacerts file included in the app, and...
 ... it works now !

How do you do that? Could you provide all the necessary files and command lines?

So the conclusion : it is necessary and sufficient to import the Certigna root CA certificate in the trust store of the Java JRE.
For the macOS version, the trust store is included in app, so, I can do it only "manually", but I'm sure you can do it definitively for me ... ! 

I'll try if you make it easy for me ;-)
