(C++) Workaround for the deprecated Crypt2.DecryptBytesENC method

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

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

    std::cout << "Encrypted: " << encryptedAsHex << "\r\n";

    success = crypt.DecryptBytesENC(encryptedAsHex,decryptedBytes);

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

    CkBinData bd;
    bd.AppendEncoded("AABBCCDDEEFF01020304","hex");

    // in-place encrypt, then get as hex.
    crypt.EncryptBd(bd);
    encryptedAsHex = bd.getEncoded("hex");
    std::cout << "Encrypted: " << encryptedAsHex << "\r\n";

    // load from hex, then decrypt.
    CkBinData bd2;
    bd2.AppendEncoded(encryptedAsHex,"hex");
    crypt.DecryptBd(bd2);
    std::cout << "Decrypted: " << bd2.getEncoded("hex") << "\r\n";
