Hi all,

I have a pair (modulus (n) ,private exponent (d)) from a RSA private
key (standard PKCS#1), and I would like to work with CryptoAPI.
The problem is when I call CryptImportKey, I need other parameters in
my private key structure (prime numbers, coefficient ...) that I don't
know how I can get it.

1) The standard says that both types of representation are valid, but
I wondered if CryptoAPI can work with the first one (only the pair
(n,d)).
2) If it doesn't, How can I get the second type from the first one?
(Getting prime numbers are enough)

Any help would be appreciated,

Regards
