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++

#include <CkRsa.h>
#include <CkPrivateKey.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkRsa rsa;

    // Generate a 2048-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 8192 bits.
    CkPrivateKey privKey;
    success = rsa.GenKey(2048,privKey);
    if (success == false) {
        std::cout << rsa.lastErrorText() << "\r\n";
        return;
    }

    // Get the private key in PKCS8 Base64 format
    const char *privKeyPkcs8Base64 = privKey.getPkcs8ENC("base64");

    // The key in base64 format will start similar to this:
    // MIIEvAIBADANBgkqhkiG9w0BA...
    std::cout << privKeyPkcs8Base64 << "\r\n";
    }
