| Whenever I look for examples using the cryptographic streams, I only ever see underlying streams as NetworkStreams or FileStreams, but not MemoryStreams. 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... |

| I'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 |

| Moved from [aspngwebservices] to [ngfx cryptography] by Todo Proudfoot Hi, I have used DES algorith to encrypt sring on Java side and trying to decrypt the same on .NET side (when we receive the data). 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?
