Wait, I didn't know Blowfish was symmetric too!

Yeah, but isn't it less secure than AES now?

I thought DES was outdated, but it's still symmetric, right?

I hope the answer isn't "Encrypt with a rubber duck" - that would be a really quacky solution!

RSA is an asymmetric algorithm, not symmetric. The question is pretty straightforward.

Haha, I bet the answer is not DES. That's so outdated, no one uses that anymore!

Hmm, I think Blowfish is also a symmetric encryption algorithm. I remember learning about it in my crypto class.

I keep mixing up symmetric and asymmetric algorithms; I hope I can remember that symmetric means the same key for both processes!

I feel like there was a practice question about symmetric vs. asymmetric encryption, and I think symmetric ones are faster?

I remember studying AES and DES, but I'm not entirely sure if there are others that fit the definition.

I think symmetric encryption algorithms are ones that use the same key for both encryption and decryption, right?

I've got this! Symmetric encryption uses a single secret key that both parties know, like DES or Blowfish. I'm confident I can identify the symmetric algorithms on this exam.

Ugh, encryption algorithms are not my strong suit. I'll have to guess on this one and hope for the best.

Okay, let me think this through. Symmetric encryption means the same key is used on both ends, right? I'm pretty sure AES is a common symmetric algorithm, but I should double-check my notes to be sure.

Hmm, I'm not totally sure about this. I know symmetric encryption uses a single shared key, but I can't remember the specific algorithms off the top of my head.
