Eccouncil 212-81 Exam - Topic 11 Question 31 Discussion

Actual exam question for Eccouncil's 212-81 exam

Question #: 31
Topic #: 11

Collision resistance is an important property for any hashing algorithm. Joan wants to find a cryptographic hash that has strong collision resistance. Which one of the following is the most collisionresistant?

ASHA2

BMD5

CMD4

DPIKE

Show Suggested Answer

Suggested Answer: D

Integrity

https://en.wikipedia.org/wiki/Cryptographic_hash_function#Verifying_the_integrity_of_messages_and_files

An important application of secure hashes is verification of message integrity. Comparing message digests (hash digests over the message) calculated before, and after, transmission can determine whether any changes have been made to the message or file.

Agreed, MD5 and MD4 are outdated and weak.

I’m a bit confused about PIKE; I don’t recall studying it much compared to SHA2, which I know is solid.

I feel like we had a practice question about hashing algorithms, and SHA2 was definitely highlighted as the stronger choice.

I remember that MD5 and MD4 are considered weak in terms of collision resistance, so I would lean towards SHA2.

I'm a bit confused by this question. I know MD4 and MD5 are considered weak, but I'm not sure how PIKE compares to SHA2 in terms of collision resistance. I'll have to think this through carefully.

Based on what I've learned, SHA2 is generally considered the most secure and collision-resistant hash function of the choices provided. I'll go with that.

Hmm, I'm not sure about this one. I know MD5 has known collision vulnerabilities, but I'm not as familiar with the collision resistance properties of the other options.

I'm a bit confused by this question. The options don't seem to directly match the description of the network port. I'll have to think this through step-by-step.

This seems like a tricky one. I'll need to think carefully about the different themes and how they relate to communicating with stakeholders.

MD4? Isn't that like the little brother of MD5 - always trying to live up to the bigger, stronger sibling? SHA2 is the clear winner here.

PIKE? Is that some kind of new fishing lure? I'll stick with the tried and true SHA2, thanks.

Yeah, PIKE is not a hashing algorithm, it's probably a fishing term.

MD5? Seriously? That's like using a cardboard shield against a cannon. SHA2 is the way to go if you want something truly collision-resistant.

Collision resistance, huh? Sounds like a wrestling move I'd want to avoid in the ring! But for a hash function, gotta go with the big guns - SHA2 all the way!
