All Implemented Interfaces:

HashingAlgorithmBuilder

public class SHA256Builder
extends DigestAlgorithmBuilder

Builder for SHA-256 hashing algorithm.

This algorithm should be sufficient for many cases (e.g. password hashing). If slightly higher execution time is not an issue for you, you can also use SHA512Builder.

You can make potential attacks harder if you use salt (e.g. by using SaltingAdapter). You can also do repeated hashing by using RepeatingDecorator if higher execution time is not an issue for you.

This class is immutable and can be considered thread safe.
