This bug is to track the progress of adding digital signature support to the core API as well as supporting tools to the viewer RI. The plan is to first add document verification support followed by signing tools.

I've checked in a rather large block of code that will validate signatures using the PKCS1 and PKCS7 certificate. Validation is currently limited to verifying if a document has been altered. Further work is needed to deal with time stamps as well as verifying a certificate chain against a trusted authority.

Marking as fixed.
ICEpdf 6.1 will introduce signature validation via new supporting classes. The Viewer RI has been updated to to show a Signatures tab in the utilities pane. This pane shows a summary of each signature validation results. It is also possible to right click on any signature annotation and open a properties dialog about the signature or view the certificates.
