Class ByteArrayFixedSaltGenerator

  • 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.

      Modifier and Type Method Description
      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).
