SHA512Managed SHA512Managed SHA512Managed SHA512Managed Class

Definition

Computes the SHA512 hash algorithm for the input data using the managed library.

Examples

The following example computes the SHA512Managed hash for data and stores it in result. This example assumes that there is a predefined constant DATA_SIZE.

array<Byte>^ data = gcnew array<Byte>( DATA_SIZE );
array<Byte>^ result;

SHA512^ shaM = gcnew SHA512Managed;
result = shaM->ComputeHash( data );
byte[] data = new byte[DATA_SIZE]; 
byte[] result;
 
SHA512 shaM = new SHA512Managed(); 
result = shaM.ComputeHash(data);
Dim data(DATA_SIZE) As Byte
Dim result() As Byte
       
Dim shaM As New SHA512Managed()
result = shaM.ComputeHash(data)

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 SHA512Managed algorithm is 512 bits.
