I agree with C, different algorithms mean different outputs.
VI

Wait, how can they be swapped? That seems off.
LA

D is false, they use different algorithms.
ME
Merri

C is definitely true, they won't match.
RO

A is true, both hashes have fixed sizes.
JU

I feel like the statement about them being based on the same hashing algorithm is definitely false, but I need to double-check that.

I practiced a question like this before, and I believe they can't be swapped since they come from different algorithms.
DI

I'm not entirely sure, but I think they might have fixed sizes depending on the algorithms used.

I remember that different hashing algorithms produce different outputs, so I think X1 and Y1 won't match.
LA

This is a good test of my understanding of hashing algorithms. I'll need to carefully consider the properties of X1 and Y1 to determine which statements are true.
LO

I think the key here is understanding that X1 and Y1 are created using different algorithms, so they can't be swapped or considered the same. I'm leaning towards C as the correct answer.

Wait, I'm a bit confused. Aren't message digests supposed to have a fixed size regardless of the algorithm used? I'll have to double-check that.
RY

Okay, I know that message digests created by different hashing algorithms won't match, so I'm pretty sure the answer is C.
AR
Arlen

Hmm, this seems like a tricky one. I'll need to think carefully about the differences between the hashing algorithms X and Y.
HA

Wait, option D? Seriously? How can they be based on the same algorithm if the question clearly states they are different algorithms X and Y?
AN
Angelo

I think option D is incorrect because the question states that they use different algorithms.
ED

C) They do not match
KI

A) They have fixed sizes
TI

Option C is definitely true. Since the algorithms are different, the resulting message digests X1 and Y1 will not match.

Haha, option D is like saying 'they're the same, but also different' - that's some quantum-level logic right there!

I agree with Jenise, because message digests have specific lengths.
JE

I think the answer is A) They have fixed sizes.
VI

Option A is correct. Message digests from different hashing algorithms will always have fixed sizes, regardless of the message size.
FR
Franchesca

No, message digests from different algorithms cannot be swapped.
LU

B) They can be swapped
