#include <CkCrypt2.h>

void ChilkatSample(void)
    {
    CkString strOut;

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    CkCrypt2 crypt;

    const char *s1 = "This is a test / = abc 123";

    // The ReEncode method converts a string from one encoding
    // to another.
    // Valid encodings are "url", "base64", "qp", "hex", "ansi", "modbase64", "base64url", "base32", "base58",
    // and any of the encodings listed here:  http://cknotes.com/chilkat-binary-encoding-list

    // Use "ansi" for an unencoded ANSI string.

    // Encode to URL-encoding:
    const char *s2 = crypt.reEncode(s1,"ansi","url");
    strOut.append(s2);
    strOut.append("\r\n");

    // Convert from URL-encoding to base64:
    const char *b64 = 0;
    b64 = crypt.reEncode(s2,"url","base64");
    strOut.append(b64);
    strOut.append("\r\n");

    // Convert from base64 to hex:
    const char *hex = 0;
    hex = crypt.reEncode(b64,"base64","hex");
    strOut.append(hex);
    strOut.append("\r\n");


    SetDlgItemText(IDC_EDIT1,strOut.getUnicode());
