    • Encryptor

      public Encryptor()
      Instantiate an encryptor.

    • Encryptor

      public Encryptor(int threads)
      Instantiate an encryptor with parallel tasks and buffer size.
      Parameters:
      threads - The number of threads to use.

    • Encryptor

      public Encryptor(int threads, int bufferSize)
      Instantiate an encryptor with parallel tasks and buffer size.
      Parameters:
      threads - The number of threads to use.
      bufferSize - The buffer size to use. It is recommended for performance to use a multiple of the chunk size if you enabled integrity otherwise a multiple of the AES block size (16 bytes).
