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 <C_CkRsa.h>
#include <C_CkPrivateKey.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkRsa rsa;
    HCkPrivateKey privKey;
    const char *privKeyPkcs8Base64;

    success = FALSE;

    rsa = CkRsa_Create();

    // Generate a 2048-bit key.  Chilkat RSA supports
    // key sizes ranging from 512 bits to 8192 bits.
    privKey = CkPrivateKey_Create();
    success = CkRsa_GenKey(rsa,2048,privKey);
    if (success == FALSE) {
        printf("%s\n",CkRsa_lastErrorText(rsa));
        CkRsa_Dispose(rsa);
        CkPrivateKey_Dispose(privKey);
        return;
    }

    // Get the private key in PKCS8 Base64 format
    privKeyPkcs8Base64 = CkPrivateKey_getPkcs8ENC(privKey,"base64");

    // The key in base64 format will start similar to this:
    // MIIEvAIBADANBgkqhkiG9w0BA...
    printf("%s\n",privKeyPkcs8Base64);


    CkRsa_Dispose(rsa);
    CkPrivateKey_Dispose(privKey);
