How is a public key used that is generated when a Microsoft Edge extension is submitted on Partner Center?

Question

While uploading my extension to Microsoft Partner Centre, I have got a "Public key" for my extension along with CRX ID and Store ID. I could not find any documentation on the use of this Public key in Microsoft Edge Add-ons. Can I know the use of this key?

Answer 1

The only thing I can find about public key in Microsoft doc is this:

The extension ID is generated based on a hash of the public key.

So I think the use of the public key is to generate extension ID.
