File Encryption and Content Protection

In my line of work engineers stamp their work with their personal Professional Engineer's stamp with data and signature to indicate that they personally have inspected the work and given their professional blessing to it. In the current digital world such practices are hard to maintain when you want to email a document. With the modern technologies it is easy to lift the stamp and signature of an electronic document and forge another document. One that the 'signing' engineer has never seen.

This FineCrypt encryption utility may be helping the engineer in protecting his seal.
