All Implemented Interfaces:

FixedSaltGenerator, SaltGenerator

public class ByteArrayFixedSaltGenerator
extends Object
implements FixedSaltGenerator

Byte-array based implementation of FixedSaltGenerator, that will always return the same salt.

If the requested salt has a size in bytes smaller than the specified salt, the first n bytes are returned. If it is larger, an exception is thrown.

This class is thread-safe.

Constructor Summary

ByteArrayFixedSaltGenerator(byte[] salt)
Creates a new instance of FixedByteArraySaltGenerator

Method Summary

byte[]	generateSalt(int lengthBytes) Return salt with the specified byte length.
boolean	includePlainSaltInEncryptionResults() As this salt generator provides a fixed salt, its inclusion unencrypted in encryption results is not necessary, and in fact not desirable (so that it remains hidden).
