Solution 2

There are a number of ways to do this: SQL supports encryption - there is an example here: http://msdn.microsoft.com/en-us/library/ms179331.aspx[^]

But I would go with encrypting it in C# using the .NET Cryptography namespace[^]. There is an example here, using DES encryption: http://msdn.microsoft.com/en-us/library/system.security.cryptography.descryptoserviceprovider.aspx[^]

As I said - there is an example there, and it is pretty simple. If you can't follow that, then you really need to look at getting more familiar with the basics before you start tackling anything to do with security - there are so many mistakes you can make which could lead to you being confident in your security, but in fact vulnerable to anyone who happens to have a quick look.
