Summary

This chapter introduced asymmetric algorithms, particularly the RSA algorithm. We saw how the asymmetric algorithm can be used to solve certain problems with symmetric algorithms by making it unnecessary to share any secret key. We also looked at how RSA works and how to program with the RSACryptoServiceProvider class in the .NET Framework. Finally, we looked at how to format RSA parameters into an XML format so that they may be shared with other parties. In the next chapter, we will continue to study asymmetric algorithms, but we will shift our attention to digital signatures, which is the other important aspect of asymmetric algorithms.
