Hi,
This is two different implementations of SHA1 algorithm. The
SHA1CryptoServiceProvider class uses the built-in Windows CSP (in native
code). The second one, SHA1Managed, is a managed alternative (so it doesn't
depend on Windows CSP. I think, the native-based SHA1CryptoServiceProvider
class has better performance.
