Solution: Encrypt data with AES

(upbeat music) … - [Instructor] Okay, let's check our work. … 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 Encrypt, … and there's your encrypted text. …
