Everyware API RSA Encrypt JSON

See more RSA Examples

Demonstrates how to RSA encrypt JSON using everyware.com's RSA public key. Perl

use chilkat();

$success = 0;

# 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.
$json = chilkat::CkJsonObject->new();
$json->UpdateString("provider_key","USER GUID HERE");
$json->UpdateString("menu_item","payment");
$dt = chilkat::CkDateTime->new();
$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->put_EmitCompact(1);

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