SHA1CryptoServiceProvider Class
Computes the SHA1 hash for the input data using the implementation provided by the cryptographic service provider (CSP). This class cannot be inherited.
For a list of all members of this type, see SHA1CryptoServiceProvider Members.

Thread Safety
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
Example
[Visual Basic, C#, C++] The following example computes the SHA1 hash for data and stores it in result. This example assumes that there is a predefined constant DATA_SIZE.
[Visual Basic] Dim data(DATA_SIZE) As Byte Dim result() As Byte Dim sha As New SHA1CryptoServiceProvider() ' This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data) [C#] byte[] data = new byte[DATA_SIZE]; byte[] result; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data); [C++] Byte data[] = new Byte[DATA_SIZE]; Byte result[]; SHA1* sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha->ComputeHash(data);
