AES, or Advanced Encryption Standard, is like a secret code language that computers use to keep our data safe.

It’s a symmetric block cipher, which is a fancy way of saying it scrambles data into a secret code that only someone with the right key can understand.

The “symmetric” part means it uses the same key to both jumble up the data (encrypt) and unscramble it back to its original form (decrypt).

What is AES encryption and how does it work?

AES encryption is a globally accepted symmetric encryption standard that transforms data into an unreadable format, using the same key for both encryption and decryption, ensuring data security and confidentiality.

You might be wondering, “What kind of data are we talking about?”

AES is used to protect all sorts of data, from your personal files on your computer to sensitive government information.

Whether you’re storing family photos or top-secret documents, AES has got you covered.

One of the things that makes AES so reliable is its block/chunk size of 128 bits.

In the world of encryption, the size of these blocks is really important.

The bigger the block, the harder it is for any bad guys to crack the code.

And with AES, you can choose a key size of 128, 192, or 256 bits, depending on how secure you need your data to be.

But AES doesn’t just rely on big block sizes to keep data safe.

It also uses something called a ‘substitution–permutation network’.

This is a series of operations that mix up the data even more, making it extra hard for anyone to decipher without the key.

You might be thinking, “This sounds complicated. Is AES really secure?”

The answer is a resounding yes. AES is considered the industry standard for encryption.

It’s been thoroughly tested and approved by top security experts around the world.
