MD5 is still used a lot, but it's not secure anymore.

I think SHA-1 is more popular these days, though.

I feel like the details about the block size and rounds might point to TIGER, but I need to double-check my notes on that.

The 64 rounds make me think of SHA-1, but I also remember that Keccak is a newer standard.

I remember studying that MD5 was replaced by something more secure, but I can't recall if it was SHA-1 or something else.

I think the hash described sounds a lot like SHA-1, but I'm not entirely sure about the specifics like the output size.

Ah, I remember learning about this hash function in class. The details match up with MD5, so I'm confident that's the right answer. Time to move on to the next question.

Okay, let's see. 128-bit output, 512-bit block, 32-bit word, 64 rounds - that sounds like SHA-1 to me. But I'll double-check the other options just to be sure.

Hmm, I'm a bit unsure about this one. The info about the Flame malware compromise has me second-guessing my initial instinct. I'll have to think this through carefully.

This one seems pretty straightforward. The details about the hash function's creator, output size, and block size are good clues to identify it.

Wait, is this a trick question? I thought we were supposed to be learning about hash functions, not guessing which one is the most hilariously outdated.
