How many prime numbers do you know of that are even?
One: 2 ;-) OK, I've never realized that e and d must both be co-prime with respect to (p-1)(q-1), only that ed=1 mod((p-1)(q-1)), and I didn't saw the implication. Sorry for this stupid question, next time I'll do more mathematics before.

The exponent of the RSA public key must be odd.
It's there any (unknown to me) security reason to be this way, or itŽs an implementation/standard option??
