java.lang.Object

org.jasypt.salt.ByteArrayFixedSaltGenerator

All Implemented Interfaces:

FixedSaltGenerator, SaltGenerator

public class ByteArrayFixedSaltGenerator
extends java.lang.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.
