BouncyCastle RSAPrivateKey to .NET RSAPrivateKey

Question

I\'m creating a certificate distribution system to keep track of clients and stuff.

What happens is:

• Client send CSR to Server
• Server checks a

Answer 1

Neither of the solutions worked for me. But I've noticed that the exception is always thrown when one of the following arrays:

parms.Modulus   = rpckp.Modulus.ToByteArrayUnsigned();
parms.P         = rpckp.P.ToByteArrayUnsigned();
parms.Q         = rpckp.Q.ToByteArrayUnsigned();
parms.DP        = rpckp.DP.ToByteArrayUnsigned();
parms.DQ        = rpckp.DQ.ToByteArrayUnsigned();
parms.InverseQ  = rpckp.QInv.ToByteArrayUnsigned();
parms.D         = rpckp.Exponent.ToByteArrayUnsigned();
parms.Exponent  = rpckp.PublicExponent.ToByteArrayUnsigned();

has a different size then its neighbor:

DP, DQ, InverseQ, P, Q

or double sized:

D, Modulus

For each of these two groups I have calculated the max length and added extra zeroes at the beginning of each array to make them the same length (the same for each group). This works, I suppose that ImportParameters checks that they are of the same length (unfortunately I don't have an access to the ImportParameters code, it seems that it calls some native library).

I'm using BouncyCastle.Crypto.dll ver 1.7
