Information on the Acrobat Reader integration key used to be
included with the Acrobat SDK and available on the Adobe web site.
The Reader integration key uses public key technology. The vendor
creates a public/private key pair. The public key is sent to Adobe
where it is digitally signed then returned to the vendor. This
digitally signed public key is then embedded into the Acrobat Reader
plug-in. The embedding process locks the key to the Reader plug-in;
so, a third party can not extract the key from an authorized plug-in
and use it in an unauthorized plug-in.
This is, in essence, a digital signing process and has two
significant advantages for Adobe. It locks a unique vendor id into
the Reader plug-in and it also allows Acrobat Reader to determine if
a plug-in has been tampered with since being built by the vendor.
On startup; Acrobat Reader validates the "Digital Signature" attached
to the Reader plug-in. If the digital signature can not be validated
then Acrobat Reader will reject the plug-in.
