Everyware API RSA Encrypt JSON

See more RSA Examples

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

require 'chilkat'

success = false

# 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(false))

# 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(true)

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