What are you actually trying to do there in terms of your actual context
of usage?

RSA_check_key is about checking that an RSA private key component values
are mathematically consistent with respect to each other - i.e. it is
about checking *all *the components are correct.  It isn't about doing
anything other than that and without n,e,d *and p and q* there isn't
much it is meant to do. Why are you missing p and q in your particular
context?

Thanks,
Tim.
