Possible duplicate: SO, math.stackexchange.com or area51.stackexchange.com/proposals/8766/…. @Mark Robinson, do you agree? – Maniero Nov 15 '10 at 23:08

@bigown - I'm not an expert so my honest answer is: I don't know. But since the answer to my question above is that it is for people doing cryptography, and since it already has 57 followers, I think it stands in its own right. – Wikis Nov 16 '10 at 8:20

@Ravi, @Mark, Since this site was not mergeed with the security.stackexchange.com one, and that one does cover applied cryptography, as in developers using encryption and building cryptosystems, I would say this should be more in the direction of research / theoretical / conceptual / algorithmical / mathy parts of crypto. – AviD Nov 19 '10 at 9:55

I'd peg this for off-topic until/unless working quantum computers exist (outside the slashdot news stories about theoretical work towards them, I don't know of any that work) – warren Aug 3 '10 at 14:30

I agree with the off-topic designation but general quantom computer + crypto questions (theoretical) should be allowed, I think. – Shul Aug 3 '10 at 20:41

If you are encrypting something today, you don't only want it to be secure against attacks that exist today. You might also want to prevent an attacker from decrypting tomorrow, next year, or in a decade. Perhaps even longer. So this is on-topic. – Zooko Aug 4 '10 at 21:03

Post-quantum crypto is an active research area, and it seems odd to simply ignore it because current QC implementations are on too small a scale to pose a threat to RSA or El Gamal. – Joe Fitzsimons Sep 17 '10 at 15:27

Imho that's way too basic for "people doing cryptography". – Tadeusz A. Kadłubowski Aug 1 '10 at 18:13

True, if you think of it in a higher level , but what about the match of both the systems? may e we should add that :) – Ravi Vyas Aug 1 '10 at 19:34

Imo it's appropriate, since knowing when to use which is just as important. – wez Aug 3 '10 at 11:04

Sorry for the typo , its math and not match and "may be" and not "may e" :-) – Ravi Vyas Aug 4 '10 at 16:25

I think the target audience should know what an initialization vector is. – Frédéric Grosshans Nov 16 '10 at 15:58

@Frédéric: I still think it would be good to cover some basic questions. It might also attract comments alluding to interesting special cases that most people have not heard about. – Thilo Dec 3 '10 at 2:44

Too vague? Although, an index of modern cryptanalytic techniques would be a great thing to have. – Zack Aug 4 '10 at 21:11

This is good because it gets at protocol design, which is often the weak point in a cryptosystem. It might, however, be too specific to be interesting. – Zack Aug 4 '10 at 21:14

This question does not relate to the topic of the proposal.
It was closed as part of an automated migration of off-topic to close votes on September 29, 2011.

I would've thought that's a good question for security.stackexchange.com as it's about risk management and policy, and not necessarily a question for crypto mathematicians. – Graham Lee Dec 15 '10 at 13:34

I consider this not a good example, because the targeted audience should know in detail what the difference is. – qbi Jul 31 '10 at 19:23

May be we should state prime numbers (instead of big prime numbers) – Ravi Vyas Jul 30 '10 at 7:16

I voted not a good example because "What's the difference between encryption and a hash" was assumed to be known by target audience, this question would fall under that definition as well. – samoz Aug 10 '10 at 2:34

@samoz - but if you're new to the field, or just "interested", you may not know about asymmetry yet – warren Aug 10 '10 at 2:44

I also voted not a good example because I've seen this question asked and answered in math.so. Some overlapping is just fine, but we might as well point to that resource. An explanation it is also found easily in Wikipedia. Maybe adding to the question some details that are not clear would be better. – skd Dec 10 '10 at 12:51

	seems more like a stackoverflow question to me – Zack Aug 4 '10 at 21:12
	If just based on theory or general methods , I think this is on topic – Ravi Vyas Aug 5 '10 at 3:52
