Hash algorithm for dynamic growing/streaming data? http://stackoverflow.com/questions/5865824/hash-algorithm-for-dynamic-growing-streaming-data data Are there any algorithm that you can continue hashing from a known hash digest For example the client upload a chunk.. the state of md5 internals to ServerB and finish the hashing There was a cool black magic hack based on md5 I found years.. a more general solution. What's more can the state of the hashing be stored in the hex digest itself So I can continue hashing..
