To decrypt a document, a certificate in the key store should match a recipient specified in the document recipients collection. If there are no matching certificates in the key store, an instance of CannotDecryptPdfException will be thrown later when the handler is used to decrypt a document.
The permissions for the decrypted document might vary, depending on the matching certificate.
