(C++) Workaround for the deprecated EncryptString and DecryptString methods

Shows how to replace the deprecated EncryptString and DecryptString methods. (Chilkat is moving away from the use of CkByteData.)

Note: This example requires Chilkat v11.0.0 or greater.

    crypt.put_Charset("utf-8");

    // ------------------------------------------------------------------------
    // The EncryptString and DecryptString methods are deprecated:

    CkByteData encryptedBytes;
    success = crypt.EncryptString(plainText,encryptedBytes);

    const char *decryptedStr = crypt.decryptString(encryptedBytes);
    std::cout << "Decrypted: " << decryptedStr << "\r\n";

    // ------------------------------------------------------------------------
    // Replace the above CkByteData usage with the following code:
    // (Chilkat is moving away from using CkByteData)

    CkBinData bd;
    bd.AppendString(plainText,"utf-8");

    // in-place encrypt
    crypt.EncryptBd(bd);

    // in-place decrypt
    crypt.DecryptBd(bd);
    decryptedStr = bd.getString("utf-8");
    std::cout << "Decrypted: " << decryptedStr << "\r\n";
    }
