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

// First build the JSON to be encrypted.
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.JsonObject')
$json = new COM("Chilkat.JsonObject");
$json->UpdateString('provider_key','USER GUID HERE');
$json->UpdateString('menu_item','payment');
// For versions of Chilkat < 10.0.0, use new COM('Chilkat_9_5_0.Chilkat.CkDateTime')
$dt = new COM("Chilkat.CkDateTime");
$dt->SetFromCurrentSystemTime();
$json->UpdateString('date_time',$dt->getAsUnixTimeStr(0));

// This build JSON like the following:

// {
//     "provider_key": "USER GUID HERE",
//     "menu_item": "payment",
//     "date_time": "1588163411"
// }

// When we sign, we'll want to sign the most compact JSON possible
$json->EmitCompact = 1;

// Everyware's RSA public key is at:  https://docs.everyware.com/docs/everyware-public-rsa-key
