Generate RSA Key and return Base64 PKCS8 Private Key

See more RSA Examples

Demonstrates how to generate a new 2048-bit RSA private key and returns the Base64 encoded PKCS8 representation of the private key. C#

bool success = false;

Chilkat.Rsa rsa = new Chilkat.Rsa();

// Generate a 2048-bit key.  Chilkat RSA supports
// key sizes ranging from 512 bits to 8192 bits.
Chilkat.PrivateKey privKey = new Chilkat.PrivateKey();
success = rsa.GenKey(2048,privKey);
if (success == false) {
    Debug.WriteLine(rsa.LastErrorText);
    return;
}

// Get the private key in PKCS8 Base64 format
string privKeyPkcs8Base64 = privKey.GetPkcs8ENC("base64");

// The key in base64 format will start similar to this:
// MIIEvAIBADANBgkqhkiG9w0BA...
Debug.WriteLine(privKeyPkcs8Base64);
