  Name Description
Public method Clear Releases all resources used by the HashAlgorithm class. (Inherited from HashAlgorithm.)
Public method ComputeHash(Byte[]) Computes the hash value for the specified byte array. (Inherited from HashAlgorithm.)
Public method ComputeHash(Stream) Computes the hash value for the specified Stream object. (Inherited from HashAlgorithm.)

  Name Description
Protected field HashSizeValue Represents the size, in bits, of the computed hash code. (Inherited from HashAlgorithm.)

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.

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.


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