Workaround for the deprecated Crypt2.MacString method

Shows how to replace the deprecated MacString method. (Chilkat is moving away from the use of CkByteData.) C++

#include <CkCrypt2.h>
#include <CkByteData.h>

void ChilkatSample(void)
    {
    bool success = false;

    CkCrypt2 crypt;

    crypt.put_Charset("utf-8");

    //  Do HMAC using SHA-256.
    crypt.put_MacAlgorithm("hmac");
    crypt.put_HashAlgorithm("sha256");

    const char *keyHex = "000102030405060708090A0B0C0D0E0F";
    success = crypt.SetMacKeyEncoded(keyHex,"hex");

    const char *inputStr = "This is a test.";

    //  ------------------------------------------------------------------------
    //  The MacString method is deprecated:

    CkByteData outData;

    success = crypt.MacString(inputStr,outData);

    //  ------------------------------------------------------------------------
    //  Workaround.
    //  (Chilkat is moving away from using CkByteData)

    crypt.put_EncodingMode("base64");
    const char *mac_base64 = crypt.macStringENC(inputStr);

    std::cout << mac_base64 << "\r\n";
    }
