Locks and Security Systems

In the realm of locks and security systems, a key is a physical object used to open or close a lock. The key fits into the lock's mechanism and, when turned, allows access to the secured area. Keys come in different shapes and sizes, each corresponding to a specific lock. Key duplication and security measures are vital aspects of this field.

Similarly, in cryptography, a key is a vital component in creating secure communication channels and protecting sensitive information.
