Ascii85 Encoding and Decoding

See more Encryption Examples

Demonstrates ascii85 encoding and decoding.

Note: Requires Chilkat v9.5.0.79 or greater.

Unicode C++

#include <CkStringBuilderW.h>
#include <CkBinDataW.h>

void ChilkatSample(void)
    {
    bool success = false;

    // First demonstrate encoding strings to ascii85 and back.
    CkStringBuilderW sb;

    success = sb.Append(L"Man is distinguished, not only by his reason, but by this singular passion from other animals, which is a lust of the mind, that by a perseverance of delight in the continued and indefatigable generation of knowledge, exceeds the short vehemence of any carnal pleasure.");

    const wchar_t *encodedAscii85 = sb.getEncoded(L"ascii85",L"utf-8");
    wprintf(L"%s\n",encodedAscii85);

    // Result is: 9jqo^BlbD-BleB1DJ+*+F(f,q/0JhKF<GL>Cj@.4 ... DII?(E,9)oF*2M7/c

    // Decode back to the original:
    sb.Clear();
    sb.Append(encodedAscii85);
    success = sb.Decode(L"ascii85",L"utf-8");
    wprintf(L"Original:\n");
    wprintf(L"%s\n",sb.getAsString());
