    What kind of encryption is used to generate the Digital Signature the .NET Framework provides classes to work with couple of common encryption algorithms.

    You can find them in the System.Security.Cryptography namespace.

    Different files formats use different ways for Digital Sigunatures and different encryption algorithms. Unless you know which algorithm is used you will not be able to decrypt the file.

    All file formats support signing differently. Word has a different way, PDF has a different way. If you are going to deal with Word and PDF then you should look at both the Word API's and the Adobe Acrobat (or similar API's) that help you work with PDF files.

    To work with Word documents you should install Visual Studio Tools for Office which provides a easy way to work with word documents. you will find better responsed on specific questions related to the Word API in the MS Word News groups or VSTO Forums on this site.
