Cryptographic hash function

Cryptographic hash functions are like locks that keep information safe and secure. Imagine that you have a box with a lock on it. The box is like the information you want to keep secure, and the lock is like the cryptographic hash function. When you put something in the box, you lock it so that no one has access to the box. In the same way, a cryptographic hash function is used to secure information so that no one has access to it. The way it works is that it takes some input (the info you want to keep secure), and turns it into an output (the “key” that unlocks the box). This output is called a “hash”, and it is different every time you use the same input. This makes it almost impossible for someone to guess the input just by looking at the output.
