}

This class extends HashAlgorithm and is the abstract representation of the SHA-1 algorithm, which creates a 160-bit hash code. Individual implementations of SHA-1 extend this class. The .NET Framework class library includes the SHA1CryptoServiceProvider class, which is the default implementation.
