What is AES-CTR?

AES-CTR is like having a super-secret code that changes every time you use it, making your messages extra safe.

Imagine you're sending secret notes to your best friend using a magic pad (but not too magic). You both have the same special pad. Every time you write a note, you pick a new number from the pad and add it to your message before sending it. Your friend uses the same number from their pad to decode it. This way, even if someone finds one of your notes, they can’t figure out the others because each one is using a different code.

AES-CTR uses a special kind of code called AES, which stands for Advanced Encryption Standard. It's like a super-smart lock that changes its combination every time you use it. Instead of just adding a number from a pad, the code mixes up your message with a changing number, making it really hard to guess what you wrote.

Because this changing number is used only once, even if someone knows part of your message, they can’t figure out the rest. It's like having a new secret pad for every note, super safe and fun!
