Suggested Answer: D

RIPEMD

https://en.wikipedia.org/wiki/RIPEMD

RIPEMD (RIPE Message Digest) is a family of cryptographic hash functions developed in 1992 (the original RIPEMD) and 1996 (other variants). There are five functions in the family: RIPEMD, RIPEMD-128, RIPEMD-160, RIPEMD-256, and RIPEMD-320, of which RIPEMD-160 is the most common.

The original RIPEMD, as well as RIPEMD-128, is not considered secure because 128-bit result is too small and also (for the original RIPEMD) because of design weaknesses. The 256- and 320-bit versions of RIPEMD provide the same level of security as RIPEMD-128 and RIPEMD-160, respectively; they are designed for applications where the security level is sufficient but longer hash result is necessary.

Dobbertin, Bosselaers, and Preneel... now that rings a bell. Definitely RIPEMD. Haha, FORK, really?

FORK? What kind of hash algorithm is that? Sounds like it could be a typo or a joke option. I'm going with D.

I'm pretty sure it's not MD5, that's a different hash function. Let me think... D) RIPEMD, that's it!

RIPEMD? Really? I thought it was SHA1. Maybe I need to review my hash algorithms again.

No, RIPEMD is actually a hash algorithm, not a cryptocurrency.

Well, if it's a 160-bit hash algorithm, it's gotta be MD5, right? I mean, that's the classic!
