Sep 4, 2018 at 10:26 comment added Maarten Bodewes Possibly, but I'm running out of time. I guess other answers will be forthcoming. I just posted the critique to allow you to alter the answer yourself (if you're willing to, this is your answer after all). Happy to reverse my vote if the issues are tackled. Just changed the answer a bit, but that's just because I altered the language within the question as well.
Sep 4, 2018 at 10:21 comment added AleksanderCH I see. Could you then answer this question? I will afterwards delete this answer as it's wrong in detail.
Sep 4, 2018 at 10:19 comment added Maarten Bodewes Sorry, but I'm just explaining why I downvoted this answer. Editing out all of the issues would significantly alter the answer, and I don't want to do that (even if I would be allowed to do that according to SE etiquette).
Sep 4, 2018 at 10:18 comment added Maarten Bodewes In general I would expect some terms such as "confidentiality", PRP and PRF to be in the answer.
Sep 4, 2018 at 10:17 comment added Maarten Bodewes Almost no hash functions (in practical use) have been proven to be irreversible, there is a section on Wikipedia about provable secure hash functions here
Sep 4, 2018 at 10:17 comment added Maarten Bodewes As for section two: symmetric encryption is easier to reverse than asymmetric encryption: not necessarily. Reversal just requires you to know the key in both cases. You need at least explain that reversal here means finding the key. A trapdoor function is a function that is easy to compute in one direction, yet difficult to compute in the opposite direction (finding its inverse) without special information, called the "trapdoor". What is the trapdoor for SHA-256?

Sep 4, 2018 at 10:14 comment added Maarten Bodewes A cryptographic hash is the workhorse in current crypto. I don't think that first section does it justice. For instance, the use of a hash within a KDF or MGF doesn't involve comparison of input values.
