I've tryed to encrypt the some string with this class and when I decrypt the data I get the following error.

I tried making one using a MemoryStream, but got all kinds errors. "Bad Data" on decryption, or something about using a Disposed stream. What's going on? Could somebody give me an example of using a MemoryStream being written to thru a wrapping c...81129173http://www.dot-net-guru.com/247reference/msgs/16/81128.aspxhttp://www.dot-net-guru.com/247reference/msgs/16/81128.aspx10 Apr 2002 16:08:00I'm looking into symetric encryption for the first time, and I'm wondering: 1) What is the IV? 2) How does it relate to the Key? 3) Do I have to keep it secret like I keep the key secret? 4) Is it "ok" to embed it in my code and use the same one all the time for a given class/use? thanks, Andy Smith Chief Code Monkey 20 81128173http://www.dot-net-guru.com/247reference/msgs/13/68736.aspxhttp://www.dot-net-guru.com/247reference/msgs/13/68736.aspx19 Mar 2002 16:47:10Hello all, This is the code I am using to http wise comm.

Carroll charlesmarkcarroll@yahoo.com Hello, Could anyone provide me a simple VB.Net sample about how to use the Rijndael algoritm to Encrypt/Decrypt Stings of data so that (later on) i could store it to disk, view it in a textbox or send it thru a TCPClient ? I don't care what the IV is, as long as i can set the Key to what i want.

But we see that the encrypted string size from Java is 2 times that of the same string encrypted in .NET. We both use the cryptography classes provided by the .NET/J2EE... Any ideas? Why is this?
