Creating a signed certificate for a native extension
You can choose to digitally sign your native extension.
Signing an extension is optional.
Digitally signing your native extension with a certificate issued
by a recognized certification authority (CA) provides significant
assurance to AIR application developers that:
When an AIR application is packaged, the AIR application’s
certificate, not the native extension’s certificate if it is provided,
is what the application’s users see.
Obtain a certificate from a certification authority. Creating
a digitally signed certificate for your native extension is the
same as creating a certificate for an AIR application. See
