For example, imagine you and I need to send data to one another that no one else should be able to read An obvious approach would be for you to encrypt the data and for me to decrypt it This is like putting a password on the data, where the password is known as the encryption key For the most commonly used kinds of encryption, I need to use the same password to decrypt the data as you used to encrypt it And so the problem has changed from how to exchange data in private to how to exchange the key securely.

If you e-mail it to me, would the same people who want to read our data be able to read the key and decrypt the data anyway Can you trust me not to write the key on my whiteboard in a public office If we meet in person, are bad people likely to be listening to us A-ha, you say what about public key cryptography Doesn t that solve the problem And, of course, the answer is that it doesn t; it just changes it in a different way Public key cryptography means you encrypt the data using a key that can be safely shared with everyone, while I decrypt it using a key that is known only to me It relies on some very clever math.

The problem becomes making sure that you are using my public key and verifying that it is me you are exchanging the data with, ensuring that my key hasn t been stolen, and so on I could continue, but you get the idea Cryptographic features must be used with caution Simply exploring the cryptographic features of NET is very different from using them to solve a real-world problem This chapter will help you do the former, but a lot of careful thought and learning is required to do the latter There are no recent books that I would recommend for NET security, but for older titles I suggest either my own book, written with Allen Jones, called Programing NET Security and published by O Reilly, or Jason Bock s book NET Security, published by Apress Table 37-1 provides the summary for this chapter..
