使用密碼編譯服務提供者 (CSP) 所提供之實作，計算輸入資料的 SHA1 雜湊值。這個類別無法被繼承。
<ComVisibleAttribute(True)> _ Public NotInheritable Class SHA1CryptoServiceProvider _ Inherits SHA1
Dim instance As SHA1CryptoServiceProvider
[ComVisibleAttribute(true)] public sealed class SHA1CryptoServiceProvider : SHA1
[ComVisibleAttribute(true)] public ref class SHA1CryptoServiceProvider sealed : public SHA1
/** @attribute ComVisibleAttribute(true) */ public final class SHA1CryptoServiceProvider extends SHA1
public final class SHA1CryptoServiceProvider extends SHA1
SHA1CryptoServiceProvider 類別的雜湊大小是 160 位元。
下列程式碼範例會計算 data 的 SHA1 雜湊值，並將它儲存於 result 之中。這個範例假設有預先定義的常數 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 );
ubyte data[] = new ubyte[data_Size]; ubyte result[]; SHA1 sha = new SHA1CryptoServiceProvider(); // This is one implementation of the abstract class SHA1. result = sha.ComputeHash(data);
