Hi Everyone,
I have a X509Certificate, I want to get a RSA object using the public key
from the cert. Is this code correct ?

public RSA GetKey(X509Certificate cert)
{
    RSACryptoServiceProvider rsa = new RSACryptoServiceProvider();
    RSAParameters keyInfo = new RSAParameters();
    keyInfo.Exponent = key;
    keyInfo.Modulus = key;
    rSA.ImportParameters(keyInfo);
    return rsa;
}

Or should I use {1,0,1} for the Exponent ?
Thanks,
Kishore
