What is the best solution in C# for computing an "on the fly" md5 like hash of a stream of unknown length? Specifically, I want to compute a hash from data received over the network. I know I am done receiving data when the sender terminates the connection, so I don't know the length in advance.
[EDIT] - Right now I am using md5, but this requires a second pass over the data after it's been saved and written to disk. I'd rather hash it in place as it comes in from the network.
