SHA512 Class

Computes the SHA512 hash for the input data.

Namespace: System.Security.Cryptography
Assembly: mscorlib (in mscorlib.dll)

Syntax

Visual Basic (Declaration)

<ComVisibleAttribute(True)> _
Public MustInherit Class SHA512 _
    Inherits HashAlgorithm

Visual Basic (Usage)

Dim instance As SHA512

[ComVisibleAttribute(true)]
public abstract class SHA512 : HashAlgorithm

Visual C++

[ComVisibleAttribute(true)]
public ref class SHA512 abstract : public HashAlgorithm

JScript

public abstract class SHA512 extends HashAlgorithm

Remarks

The hash is used as a unique value of fixed size representing a large amount of data. Hashes of two sets of data should match if and only if the corresponding data also matches. Small changes to the data result in large unpredictable changes in the hash.

The hash size for the SHA512 algorithm is 512 bits.

This is an abstract class. The only implementation of this class is SHA512Managed.

Examples

The following example computes the SHA512 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 shaM As New SHA512Managed()
result = shaM.ComputeHash(data)

byte[] data = new byte[DATA_SIZE];
byte[] result;
SHA512 shaM = new SHA512Managed();
result = shaM.ComputeHash(data);

Visual C++

array<Byte>^ data = gcnew array<Byte>( DATA_SIZE );
array<Byte>^ result;
SHA512^ shaM = gcnew SHA512Managed;
result = shaM->ComputeHash( data );
