(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_CkStringBuilder.h>
void ChilkatSample(void)
{
HCkStringBuilder sb;
BOOL success;
const char *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 = CkStringBuilder_Create();
// Load the eReceipt JSON into a StringBuilder object.
success = CkStringBuilder_LoadFile(sb,"qa_data/itida/EReceipt_ex.json","utf-8");
if (success == FALSE) {
printf("Failed to load input file.\n");
CkStringBuilder_Dispose(sb);
return;
}
// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
CkStringBuilder_Encode(sb,"itida","utf-8");
// Get the lowercase hex encoded SHA256 hash of the canonicalized JSON
// (always use utf-8)
uuid = CkStringBuilder_getHash(sb,"sha256","hex_lower","utf-8");
printf("eInvoicing UUID = %s\n",uuid);
CkStringBuilder_Dispose(sb);
