Block-My-Pasting 🔒

Block-My-Pasting is a VS Code extension designed for controlled programming labs, coding assessments, practical examinations, and supervised coding sessions.

It blocks paste functionality by default and uses PIN-based authentication to control access to pasting. It also provides a separate Master PIN for protected administrative actions such as resetting or changing the User PIN.

Important: Block-My-Pasting is designed to provide practical paste restrictions inside VS Code. A normal VS Code extension cannot completely control the operating system or prevent actions such as uninstalling the extension, using another application, terminating VS Code, or using another device.
