Wait, is it really 160? I thought it was more.

I’m pretty confident it’s 160 bits. I remember it being a key point in our encryption module.

Wasn’t there a question about SHA-1 in our last practice exam? I feel like it was related to 512 bits, but that doesn’t sound right now.

I remember studying that SHA-1 is actually 160 bits. I think it’s one of the common ones we discussed in class.

I think SHA-1 uses 128 bits, but I’m not entirely sure. It feels like I’ve seen that number somewhere.

I'm not entirely confident, but I think the answer is 160 bits. I'll double-check my notes to make sure, but that sounds right to me.

Ah, I remember learning about this in my cryptography class. SHA-1 uses a 160-bit hash value, so the correct answer is D.

Hmm, I'm a bit confused on this one. I know SHA-1 is a hashing algorithm, but I can't remember the exact number of bits it uses. I'll have to think this through carefully.

Ah, the age-old question: how many bits does SHA-1 use? My magic 8-ball says the answer is D, but I'm not feeling so sure about that.

Wait, isn't SHA-1 considered insecure these days? Maybe I should have gone with the newer SHA-256 instead.

Yes, SHA-1 is no longer considered secure. It's better to use SHA-256 for better security.
