ATransposition cipher

BStream cipher

CBlock cipher

DSubstitution cipher

Haha, I bet Kevin got this idea from a cartoon he watched. 'Just rearrange the letters, that'll keep 'em safe!' Clearly, he needs to brush up on his cryptography skills.

User 1: Kevin's encryption method seems a bit too simple.

Hold on, did Kevin really use a simple algorithm? Sounds like he might have just swapped the characters around without any real encryption. What a slacker!

He should have used a more secure method like a block cipher instead.

Yeah, it sounds like he took the easy way out with a simple algorithm.

Kevin probably used a substitution cipher, just rearranging characters.

Hmm, I'm not so sure. Rearranging characters could also be a substitution cipher, where each character is replaced with another. I'll have to think this one through a bit more.

Ah, I think Kevin used a transposition cipher. The question mentions he just rearranged the characters to produce the ciphertext, which is the defining characteristic of a transposition cipher.
