When you deal with sensitive data, you must protect it from unauthorized access or modification, and for that you need to use techniques such as encryption, digital signatures, and hashing of data. One application of digital signatures and hashing of data used often by .NET is with strong name assemblies.

This chapter begins by going through different technologies that you can use to ensure privacy, integrity, and authenticity of your data. You will look at both symmetric and asymmetric algorithms. In the second part of this chapter you will look in details at how you can ensure the integrity of you assemblies by using digital signatures.
