Combine software with hardware

You MUST have knowledge of security, APIs, 2FA, C/C++, HID, Cryptography I have source code that is tailored to a USB-HID. The current set of software: * There is a cross-platform client interface (code available) * Two-factor authentication (2FA) using a mobile app (code available) * All USB communication needs to remain password encrypted using the AES-256-CBC algorithm with base-64 encoding. USB packets are sent following the ISO 7816-4 standard. A password must be set before any command is accepted. Once again, all code is there. You just need to tweak it to make sure it works on a standard USB device and remains plug-and-play. The client interface (native app) needs to work with the device, as well as existing functionalities of the app (e.g. 2FA)
