      • increaseNonce

        public static byte[] increaseNonce​(byte[] startNonce,
                                   byte[] endNonce)
        Increase the sequential NONCE by a value of 1. This implementation assumes that the NONCE length is 8 bytes or fewer so it can fit in a long.
        Parameters:
        startNonce - The starting nonce.
        endNonce - The ending nonce in the sequence.
        Returns:
        The next nonce after incrementing.
        Throws:
        RangeExceededException - Thrown if the nonce exceeds its range

      • splitNonceRange

        public static byte[] splitNonceRange​(byte[] startNonce,
                                     byte[] endNonce)
        Returns the middle nonce in the provided range. Note: This assumes the nonce is 8 bytes, if you need to increase the nonce length then the long transient variables will not hold. In that case you will need to override with your own implementation.
        Parameters:
        startNonce - The starting nonce.
        endNonce - The ending nonce in the sequence.
        Returns:
        The byte array with the middle nonce.
        Throws:
        SecurityException - Thrown if there is a security exception
