mircea_popescu: obviously, nobody is going to have to explain to anybody why they lied or anything, but hey. free internet!
ascii_field: betcha they're already working on the necessary 'powerpoint.'
mircea_popescu: if you let them "agree" to "the reasonable" "explanation" you can laugh at them later. if you don't, it's gonna be "oh srsly we presented this before stanford" all over again
mircea_popescu: but this is why you want "the internet" to have its time to proffer its reactions.
ascii_field: didjaknow they can sign
ascii_field: mircea_popescu: so in other news one of the keys from last night has a valid sig

mircea_popescu: http://log.bitcoin-assets.com/?date=18-05-2015#1136361 << amusingly , that was for a while romania's warez source. ☝︎
Apocalyptic: by the very design of the product
Apocalyptic: i'm nearly convinced there isn't by now
Apocalyptic: oh, I thought you knew the answer and it was a challenge
ascii_field: Apocalyptic: not atm. but i'm currently occupied with other things
Apocalyptic: heh, so there is none known to you ?
ascii_field: Apocalyptic: if you come up with answer to this, please wake me up
Apocalyptic: ascii_field, i'm still thinking about your "exercice for the reader" from yesterday as to how get $othersmuckQ without at least doing a division for every modulus encountered
Apocalyptic: I misunderstood what you were saying then
ascii_field: and what i meant was that one must demonstrate that one could import the pubkey, somewhere, and verify material that was signed with it
Apocalyptic: I'm not disputing that
ascii_field: thus i conjecture that full factorization can be had, at reasonable cost, if there is a reason to attempt it
Apocalyptic: so I don't get how you can save this factorization exercice for after you sign something...
ascii_field: Apocalyptic: see earlier link re: lenstra. there are algos which are optimized for the kind of scenario which appears to exist here (a multitude of smaller primes rather than two extremely large ones)
Apocalyptic: afaik you need to have phi(N) to get d from e, and computing phi(N) is equivalently hard as getting the factorization of N
Apocalyptic: ascii_field, the part where you can sign, which implies knowledge of the private exponent d without having fully factored the modulus N
ascii_field: Apocalyptic: which part is new to you ?
Apocalyptic: ascii_field, can you comment on <Apocalyptic> "for after we demonstrate that one could 1) sign with the dud key" wait you can sign without fully factoring N ? this is news to me
Pierre_Rochard: yup, read it, this is their latest post with more details
assbot: Logged on 13-05-2015 21:42:17; asciilifeform: re: '21' etc >> 'The cornerstone of the strategy as presented would have been the release of consumer products that would turn power from wall sockets into bitcoin through the widespread dissemination of bitcoin mining chips.' << -somebody- clearly reads the 2013 #b-a logs.
ascii_field: Pierre_Rochard: http://log.bitcoin-assets.com/?date=13-05-2015#1130899 << relevant thread. ☝︎
Apocalyptic: anyway the remainding part I have is not divisible by primes below something like 1 billion if I remember my tests correctly, may still qualify as -small- though
Pierre_Rochard: little intermission to discuss -assets instead of pgp for a sec: https://www.youtube.com/watch?v=rdhNkv4ryuM (background on the meme: http://knowyourmeme.com/memes/pepe-the-frog )
ascii_field: Apocalyptic: yes, because folks are presumed to be using sane keys
Apocalyptic: ascii_field, i thought these it was pretty much NFS all the way
Apocalyptic: "for after we demonstrate that one could 1) sign with the dud key" wait you can sign without fully factoring N ? this is news to me
ascii_field: one of the state-of-art factorizers, lenstra's elliptic curve factorization,
ascii_field: the other thing is,
ascii_field: Apocalyptic: i was saving this exercise for after we demonstrate that one could 1) sign with the dud key 2) it would verify on some broken pgptron, somewhere
Apocalyptic: (the full factoring is interesting because it's the only way to compute the private exponent d) ☟︎
Apocalyptic: on a 311 decimal base number I have my doubts, even msieve refuses to crunch it ☟︎
ascii_field: Apocalyptic: try pollard-rho
Apocalyptic: but there is still this huge reminder, which is certainly not prime, that remains to be factored
ascii_field: primes? so there we go.
Apocalyptic: ascii_field, I did some trivial factoring on the reminder, got 2 more primes
ascii_field: Apocalyptic: feel free to perform, e.g., miller-rabin on the larger factor
Apocalyptic: I would like to point out that unless yesterday's modulus was fully factored, which I have no knowledge of, we actually didn't factor the invalid subkey discussed
Apocalyptic: ascii_field, noted, thanks
ascii_field: Apocalyptic, decimation: i will let mircea_popescu include this and other interesting zoological specimens in his next article.
Apocalyptic: <ascii_field> at least one falls under the classical 'generated and correctly signed with dud key' // is that key at least a classic RSA key, meaning its modulus consists of only 2 prime factors as opposed to the case discussed yesterday ?
ascii_field: decimation: most of my observations thus far are not even remotely consistent with 'bit rot.'
decimation: right, but if a cosmic ray were to zing through a ram stick, I wouldn't expect a 32 bit word to change completely?
ascii_field: decimation: this is not a consistent pattern across the entire set.
decimation: ascii_field: someone on the hn comments also listed the diff between the two keys, and it was 32-bits long
ascii_field: several have invalid self-sigs and for a subset of these, a non-rotten antecedent key can be found (as pointed out by the peanut gallery)
ascii_field: at least one falls under the classical 'generated and correctly signed with dud key'
ascii_field: ben_vulpes: presently the samples of interest fall into several categories
ben_vulpes: ascii_field: the new phukkery implies bad keygeneration in the wild, correct?
decimation: apparently the phrased was used in a song http://lyricstranslate.com/en/meine-welt-my-world.html-0
decimation: ascii_field: not to my limited knowledge. "boundlessly naive"/"unlimited innocence" or something like that.
ascii_field: curious if anyone tried to point out their 'mistake'
ascii_field: nah, this one doesn't purport to belong to anyone famous
ascii_field: we should like to harness this engine of undiscovered computronic might
trinque: I just learned that yesterday from the fine folks at HN
ascii_field: did you know that cosmic rays could perform signatures ?
ascii_field: so, one of the recent phucked keys contains two subkeys, both of which are phucked. and the self-sig is... valid.
ascii_field: ;;later tell decimation does phrase 'grenzenlos naiv' have any idiomatic meaning on top of the obvious ?
BingoBoingo: hanbot: Patched, thanks
trinque: you can click foreign keys to traverse them, so on
trinque: run a query, it barfs the results with appropriate widgets given the type of data
trinque: seems one could do an incredible database editor in this environment
trinque: I am merely scratching the surface of what I'm looking at, so far
trinque: and the idea that this GUI widget corresponds directly to some piece of data
trinque: ascii_field: incorporating the command line model into GUI programming is very cool
trinque: ascii_field: I recall somebody "doing" this by bolting webkit to a terminal emulator :p
ascii_field: trinque: enjoy the rare experience of encountering one's first non-retarded example of something (in this case, gui programming) for the first time.
trinque: looks easy enough to fix so I'll probably take a crack at it at some point
trinque: asciilifeform: turns out dieharder uses internal glibc preprocessor directives which cause it to explode when built as c99
hanbot: BingoBoingo Weak 4096 Bit... suggested edits: "the compromised key in question was" / question which was ; " not only on their total length of the key" / the total length ; "two very large prime number" / numbers ; "subverted by an adversary from the key's generation" / range from the key's ; "what failings of they keyserver" / the keyserver ; "they have yet to factored by" / yet to be factored ; "this highlight a number of" / highlights
asciilifeform: ;;later tell mircea_popescu we put this in next ver. and retest whole orchestra weekly..
asciilifeform: ;;later tell mircea_popescu observation: the only thing that doesn't parallelize linearly is the multiplication (still parallelizes as previously discussed, by split into cache-sized batches across cores.) but gcd against a known product does parallelize linearly...
mod6: oh yeah, i saw that on outside sites.
mike_c: it was discussed on hacker news. looks like there are a handful of invalid subkeys on the sks servers
mod6: how do you know they're subkeys? did I miss this in the log?
justJanne: Most of them don't seem to be valid.
mats: osprey falls outta the sky, again ☟︎
asciilifeform: http://news.softpedia.com/news/Researchers-Break-RSA-4096-Bit-Keys-481475.shtml << oddly, one fishwrap got the name spelled. ☟︎
mats: their fire will be less accurate in a firefight after a day's patrol due to muscle fatigue
mike_c: ads look like they're working (technically at least). we'll see if 8chan'ers have any money.
asciilifeform: let'em drill the sky full of holes instead of the fella behind or in front
asciilifeform: mats: good position for folks with terrible trigger discipline ?
mats: and as an aside the high ready position is inferior
mats: looks like she has her finger in the well
mats: mircea_popescu: terrible trigger discipline
jurov: ye olde tea partie
mircea_popescu: dude, three year's a lifetime for these ephemerides
asciilifeform: jurov: the derpfest in question was so blatantly an organized 'astroturf' affair that it vanished as thoroughly as anything from 20 yrs ago
jurov: "made me reminisce about the old days of Occupy Wall Street".. like, it was 20 years ago?
asciilifeform: (though it, in turn, used data from a paper, cited therein)
asciilifeform: jurov: i regret to say that i may have been responsible for the first such article.
mircea_popescu: "look in robots.txt for directories that derps inadvertently exposed"
justJanne: I’m downloading all those hidden state.gov documents right now
