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 SHA256Managed algorithm is 256 bits.
The following example computes the SHA256Managed hash for data and stores it in result. This example assumes that there is a predefined constant DATA_SIZE.
Dim data(DATA_SIZE) As Byte Dim result() As Byte Dim shaM As New SHA256Managed() result = shaM.ComputeHash(data)
