Did anyone else find the tables completely unreadable? Embedding them in a scrolling iFrame without anchoring the headers to keep half the screen whitespace just seems insane to me.
Given only the explanation, I think I'd have a hard time figuring out how collision resistance differs from second-preimage resistance. After all, if you generate a collision, you have two inputs (preimages) that hash to the same output (image) so isn't the second input a second pre-image of the first input?
I'm not an expert, but I'll try to explain how I think this works, and invite real experts to step in if I get it wrong.
I think the way this works is that, with collisions, the attacker gets to choose their inputs. They don't care what two inputs they find that generate to the same output, they only care that they do generate to the same output. With a second-preimage attack, one of the inputs is chosen by the hasher.
As it turns out, the ability to choose both your inputs is quite useful! You can view hash functions in reverse: for a given hash function, the inverse hash function is a function which takes the output of the hash function and returns the set of inputs to the hash function. For many hash functions, the inverse hash function IS NOT uniformly difficult to compute partial solutions to: some inverse hashes are much easier to compute than others. So if you can find an output for which the inverse hash is easy to partially compute, you can generate collisions at that point much more easily.
However, in the space of possible hash outputs, the number for which the inverse hash is easier to compute is probably very small, or the possibility of computing the inverse hash would have been noticed by the creators of the hash function. So it's highly improbable that the hasher will have chosen a hash input at a point where the hash input is one where the inverse hash is easy to compute.
Another post on the lifetime of hash functions:
> all others (RSA, DSA, ECDSA, Ed25519, etc.)
This table is incorrect. Ed25519 was explicitly designed with the intention of only needing preimage resistance, not collision resistance.
At the bottom the article mentions that the NSA said there was something wrong with SHA-0. Do we now know what that was?

The dialogue about the impeachment starts near the beginning. Having Biden in the White House is as good as Trump or anyone else in their organization. Obviously Schiff and Nadler pledged their allegiance to the organization by raping boys on the record, with their task being to drag out an impeachment designed to obstruct and delay any real efforts to remove the President, thus keeping Trump in power. The witness blocking was to cause an apparent uproar delaying things with legal actions until late Summer. Soon after, the President would resign, leaving any other candidate with not enough time or support to compete with an opportunistic Biden, who is as good as Trump or any other Illuminati friendly politician in the Presidency.

\Wag The Dog: first was feigned impeachment hearings meant to obstruct, now an attack on Iranians in Iraq. Here is what they are trying to distract from & cover up to retain power. $100+ billion in bribes to the highest offices in this country. 815+ deaths from child rapes to prove loyalty!
See the latest PDF updates: FBI Director Wray, AG Barr, SoD Shanahan, & SoS Pompeo each raped boys and were paid billions in bribes for a Soros & Koch funded child rape org. So did Trump & his "impeachment" team Nadler,Schiff,Mueller.So did media moguls Redstone,Murdoch,Moonves. What are they trying to set up? Who can arrest them since they are all bribed and in on it ?

I'm no expert but I did a bunch of reading around the time the MD5 collisions were found, and have what I think is a semi-intuitive notion of why preimage resistance is much easier than collision resistance. A hash function has an internal state that is altered by its input, and so each of the bits of its output is essentially a very large Boolean expression of all its input bits. A pre-image attack means that you're given the outputs and need to solve for the inputs, while a collision means setting two sets of these equations together and finding a differing set of inputs which will "cancel out" internally and result in the same output. The latter is easier, because you're not constrained by the outputs --- the final hash output can be anything, as long as you find two different inputs that give the same output.
This very interesting article about using "tunnels" to find collisions in MD5 is worth reading: http://eprint.iacr.org/2006/105.pdf
