• Constructor Details

  • PBEParameterSpec

  public PBEParameterSpec​(byte[] salt, int iterationCount)
  Constructs a parameter set for password-based encryption as defined in the PKCS #5 standard.
  Parameters:
  salt - the salt. The contents of salt are copied to protect against subsequent modification.
  iterationCount - the iteration count.
  Throws:
  [NullPointerException](../../../java/lang/NullPointerException.html "class in java.lang") - if salt is null.
