Applying digital signature to documents

Hi Friends,
I have to store some documents (word, pdf, images and text) files in sql server database. I want to apply digital signature to these documents before storing documents in sql server. When user will see thses documents , they may also request to varify that the document is not tampered after digital signing. Can anyone please tell me how to achieve this in asp.net website. Also suggest some tools if It can not be done by doing just some coding in c#.

Thanx in advance.

If this is not suitable, I believe that you will need a third party tool:
