message digest - c# fast hash calculation -

I am looking for AC # wrapper in native MD5 or SHA1 library to improve the performance of the hash count performance.

First I switched SharpZipLib to zlib and increased the display to more than 2x. (Well, you have to keep in mind that you have the correct zlib.so or zlib.dll based on OS and hardware, but it remains closed).

Will it be value for MD5 or SHA1 or both .NET and Mono already dependent on a basic implementation?

(edited) Apart from this: If I have to paste on MD5CryptoServiceProvider, is there any way in which I can calculate a hash of the file I am reading this? I mean, send bytes in chunks, but still calculate the whole hash?

The MD5 and SHA1 rely on the original implementation, even then it is possible that C ++ solution + It can be a bit faster, because you can reduce the number of method and optimize the original implementation.

Keep in mind that resident (SHA1CryptoServiceProvider) can be 3x faster than managed one (SHA1Managed).

  using the system; Using System.Collections.Generic; Using System.Linq; Using System.Text; Using System.Diagnostics; Using System.Security.Cryptography; Namespace Console Application 22 {Class Program {Static Zero Profiles (String Description, Intession, Action Throw) {// Clean GC. Select (); GC.WaitForPendingFinalizers (); GC.Collect (); // warmc func (); Var clock = stopwatch Startup (); For (int i = 0; i  {unmanaged.ComputeHash (buffer, 0, buffer lang);}); Console.ReadKey (); }}}  

 managed time elapsed 891 ms unmanaged time had passed 336 ms 

keep in mind as well Not unmanaged, unmanaged implementation is mixing 100 MB of data in 300 milliseconds, this can be a very difficult obstacle
