Dinesh,
Here is the code to read in the certificate from the certificate
file, thats pretty straight forward. You can get the public key
off the certificate, but since RSA is an asymetric algorithm you
will need the private key as well.
// Declare locals.
byte[] decodedCertificateData = null;
StreamReader reader = null;
string encodedCertificateData = null;
X509Certificate certificate = null;
// Open the file and read its contents into a string.
reader = new StreamReader(@"..\..\Certificate.b64");
encodedCertificateData = reader.ReadToEnd();
reader.Close();
// Convert the Base64 encoded string to a decoded array of bytes
// and pass it to the X509Certificate constructor.
decodedCertificateData =
Convert.FromBase64String(encodedCertificateData);
certificate = new X509Certificate(decodedCertificateData);
You need to reference the System.Security.Cryptography.X509Certificates
namespace in your application code. Hope this helps!

Subject: [DOTNET] Using Verign Keypair in .NET Cryptography
I received following SSL ID from verisign .
Now can anyone tell me how to convert this SSL ID to RSACryptoService
Parameters, so that I could use it to encrypt decrypt using
RSACryptoServiceProvider class?
