XML signature validation in AIR
Adobe AIR 1.5 and later
the classes in the Adobe® AIR® XMLSignatureValidator API to validate
digital signatures conforming to a subset of the W3C recommendation
for XML-Signature Syntax and Processing (http://http://www.w3.org/TR/xmldsig-core/). XML
signatures can be used to help verify the integrity and signer identity
of data or information.
XML signatures can be used to validate messages or resources
downloaded by your application. For example, if your application
provides services on a subscription basis, you could encapsulate
the subscription terms in a signed XML document. If someone attempted
to alter the subscription document, validation would fail.
You could also use an XML signature to help validate downloaded
resources used by your application by including a signed manifest
containing digests of those resources. Your application could verify
that the resources have not been altered by comparing the digest
in the signed file with a digest computed from the loaded bytes.
This is particularly valuable when the downloaded resource is a SWF
file or other active content that you want to run in the application
