Any valid X.500 distinguished name is supported (e.g., CN=MyCompany or OU=Team, O=Corp, C=US). Use --manifest when generating to auto-match.

For production distribution (Microsoft Store or enterprise), obtain a certificate from a trusted Certificate Authority. Default password: Generated certifica
