Examples of java.math.BigInteger.subtract()

java.math.BigInteger.subtract()
Returns a BigInteger whose value is {@code (this - val)}. @param val value to be subtracted from this BigInteger. @return {@code this - val}

            phi = p;
            p = q;
            q = phi;
        }


        pSub1 = p.subtract(ONE);
        qSub1 = q.subtract(ONE);
        phi = pSub1.multiply(qSub1);


        //
        // calculate the private exponent
