Changes to My current PHP(Laravel) Stock Management, Point of Sale & Invoicing application

Hi,

I´m looking for a developer to do some changes in my inventory, Point of Sale & Invoicing application in which I need to add code to generate digital signature with private / public RSA key using OPENSSL for each sell, sell_return, purchase, purchase_return, stock transfers document.

The system already creates all document but I need to add code to generate a hash key on each created document in transactions table by signing a concatenation of 5 existing different fields on each document record.

Please check the attached document with the Specification of the required changes.

Best Regards,

Alvaro da Rocha
