(Unicode C) Egypt ITIDA Generate eReceipt UUID
Demonstrates how to generate the eReceipt UUID for Egypt ITIDA.
Note: This example requires Chilkat v9.5.0.92 or greater.
#include <C_CkStringBuilderW.h>
void ChilkatSample(void)
{
HCkStringBuilderW sb;
BOOL success;
const wchar_t *uuid;
// This example assumes the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.
// Note: This example requires Chilkat v9.5.0.92 or greater.
// (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
sb = CkStringBuilderW_Create();
// Load the eReceipt JSON into a StringBuilder object.
success = CkStringBuilderW_LoadFile(sb,L"qa_data/itida/EReceipt_ex.json",L"utf-8");
if (success == FALSE) {
wprintf(L"Failed to load input file.\n");
CkStringBuilderW_Dispose(sb);
return;
}
// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
CkStringBuilderW_Encode(sb,L"itida",L"utf-8");
// Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
// (always use utf-8)
uuid = CkStringBuilderW_getHash(sb,L"sha256",L"hex_lower",L"utf-8");
wprintf(L"eInvoicing UUID = %s\n",uuid);
CkStringBuilderW_Dispose(sb);
}
