Get Base64 Public Key from Private Key

See more ECC Examples

Demonstrates how to get the public key in base64 format from a private key. C++

#include <CkBinData.h>
#include <CkPrivateKey.h>
#include <CkPublicKey.h>

void ChilkatSample(void)
    {
    bool success = false;

    // Load a private key from base64.
    CkBinData bd;
    success = bd.AppendEncoded("MHQCA....n0Q==","base64");

    CkPrivateKey privKey;
    success = privKey.LoadAnyFormat(bd,"");
    if (success == false) {
        std::cout << privKey.lastErrorText() << "\r\n";
        return;
    }

    CkPublicKey pubKey;
    privKey.ToPublicKey(pubKey);

    const char *pubKeyBase64 = pubKey.getEncoded(true,"base64");
    std::cout << pubKeyBase64 << "\r\n";
    }
