One thing SHA-256 has going for it is that millions can be made from finding pre-image weaknesses in it, because it's used in Bitcoin mining. If you could "figure out" SHA-256, and use it to take over Bitcoin mining, you'd make $2M the first 24 hours, at current rates. And if you play it wise, it could take a long time before anyone figure out what's going on.
With regards to market price for a successful attack, I don't think any hash function stands close to SHA-256. And for that reason I think it would be the right choice.

- runeks 10y agoI think the claim is interesting, and I certainly wouldn't reject it. But just relaying someone else's claim, without any substantiating argument, I find quite uninteresting.
- wolf550e 10y agoJean Philippe Aumasson[1] is an important currently active cryptographer who studied this particular problem closely. If he says he does not expect an algorithmic break of SHA2, I believe him that I don't need to plan to switch from SHA2 to SHA3 in an hurry. I don't have the math to understand a more detailed explanation for his reasons to make such a statement. If you do have the math, ask him. 1 - https://131002.net/index.html https://131002.net/index.html
