    • getSecureRandom

      public SecureRandom getSecureRandom()
      Gets the secure random generator. Intended for generation of initialisation vectors and other purposes that require a secure random generator.
      Returns:
      The specific secure random generator (if available), else the default system one.

    • setSecureRandom

      public void setSecureRandom(SecureRandom randomGen)
