Wildcard Cert Support

[stealthybox]

Hey Filippo,
Thanks for putting together this tool -- I hacked a solution for this use case on Windows before and it was not easy to do.

The first thing I tried was to create a wildcard cert:

ERROR: "*.test.com" is not a valid hostname or IP

This regex doesn't allow asterisks which is at least part of the issue:

Should we support this?

Cheers! 🦄

re := regexp.MustCompile(`^[\*|0-9A-Za-z._-]+$`)

should be good enough

nice!
thanks @FiloSottile
