public class StringFixedSaltGenerator extends java.lang.Object implements FixedSaltGenerator
String based implementation of
FixedSaltGenerator
, that will always return the same salt. This salt is returned as bytes using the specified charset for conversion (UTF-8 by default).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.
