How can I get the private exponent value?
Yes. This is the usual Chinese Remainder Theme representation. It is commonly used because it saves about 3/4 of calculation time. If you do not want to use it, just calculate 1 congruent e*d mod phi(n) e is the public exponent phi(n) = p-1 * q-1 and you can calculate d if you compute the inverse of e mod phi(n). Just look into a crypto book and some math algebra.
