----------------------------------------------------------- From: Richard-Hsu Message 1 in Discussion rot13 /rot ther'teen/ [Usenet: from "rotate alphabet 13 places"], v. The simple Caesar-cypher encryption that replaces each English letter with the one 13 places forward or back along the alphabet, so that "The butler did it!" becomes "Gur ohgyre qvq vg!" Most Usenet news reading and posting programs include a rot13 feature. It is used to enclose the text in a sealed wrapper that the reader must choose to open - e.g. for posting things that might offend some readers, or spoilers. A major advantage of rot13 over rot(N) for other N is that it is self-inverse, so the same code can be used for encoding and decoding. Ok. Here is what I am getting at. I want all of us interested to come up with our own rot13 implementation in C#, VB.NET or any other .NET language. Ideally we should provide two implementations 1) a simple working one and 2) an optimized one. The simple one should be fairly easy to implement since we are only getting it to work and not thinking about time (running speed) or space (memory) effiencies. However, what will be interesting is the optimized version of it. I can already imagine all sorts of way I am going to try to make it faster. Basically, the function will take a string and return the processed (rot13'ed) string. Since I am from Kolkata, I will post further thoughts/code on this one in the Kolkata User Group site. I have already posted more info and my working (a.k.a. naive) version here (http://groups.msn.com/kolkatanet/general.msnw?action=get_message&mview=0&ID_Message=210) Regards, Richard. ----------------------------------------------------------- To stop getting this e-mail, or change how often it arrives, go to your E-mail Settings. http://groups.msn.com/BDotNet/_emailsettings.msnw Need help?
