Solution: Encrypting data with AES

“

Okay. Now let's check our work. You are to encrypt data using AES and then answer a few questions. So I'm here at the web page, and I've entered the key, and I've entered the small block of data. So let's go over the algorithms, and we'll drop this down. But now it gives us a lot of choices. Now I asked you to encrypt using AES, which is the Advanced Encryption Standard. And the original name for AES is Rijndael, and you see these three listed down below. So we're going to select Rijndael. But we're going to select the longest key length which is 256 because that's the strongest option. And then for the modes, we'll drop that down. And here, we see a lot of choices as well. Well, now Electronic codebook is going to be the least secure, so we're not going to select that. But for most of us, cipher block chaining will be fine. And we'll select that. Then down below, we'll say Encrypt. And there's your encrypted text. And as you can see, the message would be meaningless to anyone who…
