Secret-Key Encryption in .NET CF Messages   Related Types This message was discovered on microsoft.public.dotnet.framework.compactframework. Post a new message to this list... Wan Zeng Hi, I am learning data encryption, and I have couple of quesitons need some immediate help. Thanks in advance. 1. Amond all the Secret-Key Encryption methods implimented in .NET framework, I think Rijndael is the best to use. Can anyone verify this for me? 2. I understand the System.Security.Cryptography is not available in MS .NET CF. I found OpenNETCF implimented similar functionalities, but it seemes Rijndael is not completely impliment? Is this true? otherwise, can anyone provide a snipet of the sample code on how to use Rijndael implimented in OpenNETCF? Any help is appreciated. Thanks. Wan Reply to this message...

(also, Rijndael will be in CF v2 for Whidbey) the next best one is TripleDES. use it something like this: TripleDESCryptoServiceProvider tdcsp = new TripleDESCryptoServiceProvider(); //set a 24 byte key (or use random) //the IV is 8 bytes (you might need to set that to 8 random bytes) tdcsp.Key = sharedKey; byte [] cipher = tdcsp.EncryptValue(data); byte [] clear = tdcsp.DecryptValue(cipher); Thanks, casey http://www.brains-N-brawn.com "Wan Zeng" <Click here to reveal e-mail address> wrote in message news:Click here to reveal e-mail address...
