If you already have the algorithm implemented in ASP, you should be able to port it over to .NET fairly quickly. Also, check out the following sites: http://www.ncat.edu/~grogans/algorithm_breakdown.htm http://www.4guysfromrolla.com/webtech/010100-1.shtml "Applied Cryptography" also contains a description of RC4. It's pretty easy to code - doing it .NET shouldn't take much time. You could also do P/Invokes to the CryptoAPI as it contains an implementation of RC4.
