String Encryption with VB.Net
Added 29 Jul 2008
In this article Brian Patterson will cover some
of the encryption classes provided in the .NET Framework. Once you have
got a grasp on how to use these algorithms, he will wrap things up with
a sample order application that will encrypt credit card information
before saving it to either a SQL Server or Oracle database server.More
often than not, you have the need to encrypt data in memory and then
later save that data out to a database or just hang onto it for the
duration of your application. If you have searched the various .NET
help files, you may have encountered encryption examples that always
deal with encrypting the contents of a file. This isn't very useful
when you need to encrypt something that isn't already contained within
a file - saving information to a file just to encrypt it and load it
back it is rather ludicrous!

Requirements
Before we get too involved there are a few things you should be familiar with to fully understand this article and get the most out of the sample application:
