Imagine you have a special box with a lock, and only you have the key to open it. This box is like your secret diary or some private information that you want to keep safe from others. In the same way, some people use a type of lock known as encryption to keep their digital information safe, like their emails or files.
However, sometimes authorities might need to access this encrypted information for legal reasons, like during investigations into crimes or terrorism. Key Disclosure Laws are rules that require people to give authorities a key to access their locked digital information when needed for such investigations.
Basically, it means that just like you might have to give the key to your special box to an adult in certain situations, some people may have to give their encryption key to the authorities to help them with important investigations.
