Computes the SHA256 hash for the input data using the managed library.
For a list of all members of this type, see SHA256Managed Members.
[Visual Basic] Public Class SHA256Managed Inherits SHA256 [C#] public class SHA256Managed : SHA256 [C++] public __gc class SHA256Managed : public SHA256 [JScript] public class SHA256Managed extends SHA256
Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.
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.
[Visual Basic, C#, C++] 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.
[Visual Basic] Dim data(DATA_SIZE) As Byte Dim result() As Byte Dim shaM As New SHA256Managed() result = shaM.ComputeHash(data) [C#] byte data = new byte[DATA_SIZE]; byte result; SHA256 shaM = new SHA256Managed(); result = shaM.ComputeHash(data); [C++] Byte data = new Byte[DATA_SIZE]; Byte result; SHA256* shaM = new SHA256Managed(); result = shaM->ComputeHash(data);
