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.) C++

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

void ChilkatSample(void)
    {
    bool success = false;

    CkCrypt2 crypt;

    crypt.put_CryptAlgorithm("aes");
    crypt.put_CipherMode("cbc");
    crypt.put_KeyLength(128);
    crypt.put_PaddingScheme(0);
    crypt.SetEncodedKey("000102030405060708090A0B0C0D0E0F","hex");
    crypt.SetEncodedIV("000102030405060708090A0B0C0D0E0F","hex");

    success = false;

    crypt.put_Charset("utf-8");
    const char *plainText = "text to be encrypted";

    //  ------------------------------------------------------------------------
    //  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";
    }
