#include <CkStringBuilder.h>
#include <CkCrypt2.h>

void ChilkatSample(void)
    {
    CkString strOut;

    //  Note: Requires Chilkat v9.5.0.65 or greater.

    CkStringBuilder sb;
    sb.Append("The 5 men of 223rd St");
    strOut.append(sb.getAsString());
    strOut.append("\r\n");

    //  Encode the utf-8 byte representation of the string in the
    //  UN/EDIFACT syntax level A character set.
    sb.Encode("eda","utf-8");
    strOut.append(sb.getAsString());
    strOut.append("\r\n");

    //  EDA Output should be: BTME027FCF6CFARFI94JT6.)F(14KJ2U

    //  Decode back to the original string.
    sb.Decode("eda","utf-8");
    strOut.append(sb.getAsString());
    strOut.append("\r\n");
    strOut.append("----");
    strOut.append("\r\n");

    //  The following requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  The "eda" encoding can be used anywhere within Chilkat.
    //  For example, with the Crypt2 API
    CkCrypt2 crypt;
    crypt.put_CryptAlgorithm("aes");
    crypt.put_CipherMode("cbc");
    crypt.put_KeyLength(256);
    crypt.put_EncodingMode("eda");

    const char *ivHex = "000102030405060708090A0B0C0D0E0F";
    crypt.SetEncodedIV(ivHex,"hex");
    const char *keyHex = "000102030405060708090A0B0C0D0E0F101112131415161718191A1B1C1D1E1F";
    crypt.SetEncodedKey(keyHex,"hex");

    const char *encStr = crypt.encryptStringENC("The quick brown fox jumps over the lazy dog.");
    //  The output is UN/EDIFACT syntax level A
    strOut.append(encStr);
    strOut.append("\r\n");

    //  Now decrypt:
    const char *decStr = crypt.decryptStringENC(encStr);
    strOut.append(decStr);
    strOut.append("\r\n");


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());

    }
