    Cryptography
    Pune-C#
    This article provides an overview of Cryptography Classes of the Microsoft.NET Framework. It will guide you step-by-step, on how to use Cryptography classes in your program.
    Encrypting SOAP Messages
    MSDN
    One of the key concerns for developers working with Web Services is security. Because the data is sent in plain text and is routed across the Internet to reach its final destination, anyone can potentially view the message exchange. In the case of the example above, this may not be an issue. However, what if the exchange consisted of a request to a bank, and the response contained a list of account numbers and balances, or perhaps a request that returned something even more interesting, such as a credit card number? This article discusses techniques for encrypting SOAP messages.
    Encryption/Decryption
    The Code Project
    A .Net SymmetricAlgorithm security class wrapper for in memory encryption/decryption with a private key.
    File Encryption
    C# Corner
    In this article and code example I've used private-key encryption to encrypt files.
    Security: Protect Private Data with the Cryptography Namespaces of the .NET Framework
    MSDN
    The .NET Framework includes a set of cryptographic services that extend the services provided by Windows through the Crypto API. In this article, the author explores the System.Security.Cryptography namespace and the programming model used to apply cryptographic transformations. He discusses reasons why cryptography is easier in .NET than it was before, including the easy programmatic acccess developers have to the cryptography APIs and the difference between symmetric and asymmetric algorithms. Along the way, a brief discussion of the most widely used algorithms, including RSA, DSA, Rijndael, SHA, and other hash algorithms, is provided.

    XMLDOM-safe DES CryptoStream Library in VB.NET
    Egg Head Cafe
    One of the common things we need to do when passing our XML documents around is to be able to encrypt key data elements so that they are kept from prying eyes. Since I'm working on a lot of .NET stuff now, I thought I'd take the time to practice my VB.NET to write a little DES CryptoStream class library. The neat thing about this class is that I do a final encoding of the encrypted input string as Base64 so that it can be inserted in an XML document for streaming over http without fear about those nasty little illegal characters that make XML parsers puke. And, when you pass in an encrypted element to be decrypted, your base64 gets unwound automatically so the original encrypted string can be decrypted.
