All Implemented Interfaces:

Serializable, Hash

public class Sha256Hash
extends AbstractHash

Generates an SHA-256 Hash from a given input source with an optional salt and hash iterations.

See the AbstractHash parent class JavaDoc for a detailed explanation of Hashing techniques and how the overloaded constructors function.
