Digital Signatures for PDF documents

Why use them?

A digital signature is a cryptographic based scheme to provide assurance that a document has not been modified or tampered with since the signature was applied. The cryptographic "certificate" validates that a particular user is who they say they are. The result is a signed document that can be validated from two perspectives: the identity of the signatory as well as the integrity of the original document.

A server based signing solution is a significant step toward simplifying the process of using Digital Signatures in an automated workflow. The user does not need to go through a multi-step process in order to apply the signature which results in significant savings related to end-user training. For integrators, the software is simple to implement within an overall Digital Signature solution due to a variety of programatic interfaces.

Highlights
