Adobe AIR 1.0 and later
All AIR installer files are required to
be code signed. Code signing is a cryptographic process of confirming
that the specified origin of software is accurate. AIR applications
can be signed using either by a certificate issued by an external certificate
authority (CA) or by a self-signed certificate you create yourself.
A commercial certificate from a well-known CA is strongly recommended
and provides assurance to your users that they are installing your
application, not a forgery. However, self-signed certificates can
be created using
from the SDK or using either
Flash, Flash Builder, or another application that uses
certificate generation. Self-signed certificates do not provide
any assurance that the application being installed is genuine and
should only be used for testing an application prior to public release.
