Definitely 160-bit. It's a standard for SHA-1.

SHA-1? More like SHA-OOPS, am I right?

I feel like I mixed up SHA-1 and MD5; I think MD5 is 128 bits, so SHA-1 must be 160 bits, right?

I’m pretty confident that SHA-1 outputs a 160-bit digest. I recall it being a common topic in our study sessions.

I remember practicing a question about hash functions, and I think SHA-1 was specifically mentioned as 128 bits, but that seems off now.

I know SHA-1 is a cryptographic hash function, but I can't quite recall the exact bit length of the output. Let me quickly scan my notes to refresh my memory.

Easy, SHA-1 produces a 160-bit message digest. I'm confident about that, so I'll just write down the answer and move on to the next question.

Wait, is it 128-bit or 160-bit? I'm a little fuzzy on the specifics of the SHA-1 algorithm. I'll have to review that section again before answering.

Okay, I remember learning that SHA-1 generates a fixed-length output, so this should be a straightforward question. Let me think this through step-by-step.

Hmm, I think SHA-1 produces a 160-bit message digest, but I'll double-check that in my notes just to be sure.
