My father passed away leaving me a company that specializes in Point-of-Sales for small grocery store chains.
A critical function that interfaces with our website stopped functioning when our SSL certificates were renewed.

I am looking for a bypass on the web-based security all together. One of the core DLL files handles checking a circuit board serial number and retrieving/verifying its expiration date. I need a rewrite of the DLL that does essentially "nothing" allowing me to use any board in any machine and ignore the expiration date or bypass the expiry check.

I have the original full project and copy of the current DLL, available upon hiring.

Fast development is of the upmost importance. A significant bonus for a quick turnaround can be discussed.
