Computes the SHA1 hash value for the input data using the implementation provided by the cryptographic service provider (CSP). This class cannot be inherited.

Public NotInheritable Class SHA1CryptoServiceProvider _
Inherits SHA1

public final class SHA1CryptoServiceProvider extends SHA1
The hash size for the SHA1CryptoServiceProvider class is 160 bits.
The following code example computes the SHA1 hash value for data and stores it in result. This example assumes that there is a predefined constant DATA_SIZE.
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)
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);
array<Byte>^ data = gcnew array<Byte>( DATA_SIZE );
array<Byte>^ result;
SHA1^ sha = gcnew SHA1CryptoServiceProvider;
// This is one implementation of the abstract class SHA1.
result = sha->ComputeHash( data );
