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 SHA256 algorithm is 256 bits.
This is an abstract class. The only implementation of this class is SHA256Managed.
The following example computes the SHA256 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; SHA256 shaM = new SHA256Managed(); result = shaM.ComputeHash(data);
