PBKDF2
PBKDF2 is like a treasure box, but it's locked with a very complicated code. You want to open the treasure box, but you don't know the code. So, you need to make a special key to unlock the box.
This is where PBKDF2 comes in. It helps you create that special key. Here's how it works:
First, you choose a password (let's say it's "dog"). But a password alone can't unlock the treasure box. So, we need to mix the password with some other secret code that only you know. Let's call that secret code the "salt".
Next, we use a special formula to mix the password and salt together. This formula is like a magic spell that turns the password and salt into a new, complicated code. That new code is your special key!
But wait, there's more. We don't want people to be able to guess your password by trying lots of different combinations. So, we need to make it really hard for them to guess.
To make it harder, we use the magic formula not just once, but many times. Each time we use it, the code becomes even more complicated. It's like covering the treasure box with layers and layers of locks.
Finally, when we have a truly complex key, we can use it to unlock the treasure box. Ta-da! We can get to the treasure inside (or whatever secret information was hidden away).
So, PBKDF2 is a tool that helps us protect our secrets by making a very strong key that only we can unlock.
