'Install a NPAPI Plugin in Safari on MacOS

I have a NPAPI plugin that communicates with chipdrives to sign data. It does not display anything. The plugin supports the NPAPI interface. I can install it in Firefox, packaged as a XPI file. I can install it in Chrome using a CRX file. I have a CAB for IE. Works on MacOS for Chrome and Firefox too. The only unsupported browser by now is the Safari Browser. (And Opera but noone cares).

How do I have to package the plugin that it can be installed in safari on MacOS?

You can provide a single installer (.pkg etc.) for all browsers by following Apples install instructions.
