I'm at the webpage, and then down below, I put the key, Graytigerkittens, and then the small block of text, Confidentiality protects data against unauthorized disclosure. Now, the questions are what algorithm did you select and why, and what key length did you select and why? So let's go over to the algorithms, and the dropdown menu gives us lots of choices. I'll scroll down. I asked you to encrypt using AES, which is the Advanced Encryption Standard. And the original name for AES is Rijndael. So we're going to select Rijndael, but we're going to select the longest key length, 256. Then the question is what mode did you select and why? Over here, you can see that there are a number of different modes we can select. Electronic code book would be the least secure, but for most of us, cipher block chaining would be the most appropriate. Down below, we say…
