Looking up into Crypto.PublicKey.RSA, I see there is a computed value
named "u" for which I can't see the use. The value of "u" is the
inverse of p modulo q, in the code:
    obj.u = pubkey.inverse(obj.p, obj.q)
Can someone tell me where this value could be used in the RSA scheme?
(it is not used in the code anyway)
