1When should I use this AES encryption tool?

Imagine you're sending a sensitive password or coordinates over an insecure message—encryption is your secret shield. Our tool helps you wrap your text in a digital layer that only someone with the correct key can ever open.

2Is it really true that my keys and messages stay on my computer?

Yes, that's exactly how our technology works. We use 'client-side' processing, which is like have a personal vault. Your secret keys and text never leave your browser for any reason.

3Is AES-256 really that secure?

Have you ever wondered if a supercomputer could simple 'guess' your password? AES-256 is the same standard used by governments and banks worldwide; it would take millions of years for even the most powerful computers today to brute-force a truly strong key.
