Hmm, a series of Caesar ciphers... Gotta be the Vigenère cipher! I bet the keyword is something like 'password' or 'abc123'.

Block ciphers? Nah, that's not it. I think I'm going with the Vigenère cipher. Sounds fancy, must be the correct answer.

I'm not sure, but I think Vigen re cipher is the right choice because it uses a keyword to create different Caesar ciphers.

I agree with Janna, Vigen re cipher makes sense for this type of encryption.

The Vigenère cipher is the answer! It uses a keyword to create a series of Caesar ciphers. I'm pretty sure about this one.
