shinohai: ty mod6 !
mod6: Most welcome.
mod6: How goes tonight?
shinohai: Not bad, gonna turn in earl been up since 4 am :/
mod6: ah, wow. ya, get some rest Sir.
lobbes: while probably elementary to most here, I just discovered that I can send POST requests with curl. One single line! The simple joys of n00bdom. ☟︎
lobbes: anywho, that was the piece of the puzzle I needed to solve for this 'stop-gap' archive solution. I'ma start putting these pieces together. Will keep everyone posted
trinque: great lobbes
trinque: curl can do just about any http-ment you want, manpage is your friend
lobbes: powerful tool, I'm finally starting to grok
lobbes: ultimately, my plan is that lobbesbot will just store urls to-be-archived in a database. A separate process will do the submitting/downloading of zip to/from archive.is. Whenever a better www-to-zip comes along I can just switch out the later process with it
doppler: very handy that it can handle url-encoding, etc. too
trinque: lobbes: decoupling sounds wise to me
trinque: archiver process breaks, can fix, restart, keep munching on work queue ☟︎
trinque: all of deedbot's connected services work in that manner
lobbes: I've always admired the 'keep data and code as separate as possible' approach you take trinque. From what I can grok, that is
lobbes: makes sense at least
lobbes: has been in-line with some meat-world mentors I was blessed to have
lobbes: anyways, for the wotpastes specifically, I plan to download and store those myself from the get-go (and NOT route them through archive.is), seeing as those are easily 'flagged' due to the predictable url. To alf's point, even if archive.is stays up, diddling is always a threat. Any bits I can do without it now is +ev imo ☟︎

asciilifeform: in quite other vintage lulz, http://www.ominous-valve.com/xerf.html >> 'The United States lost this war, after Brinkley veered off into Nazi politics. He became a Hitler sympathizer, dropping the good-doctor act for a different kind of mass psychology... ...The US government had put up with goat glands, but those didn't sabotage FDR's efforts to swing pre-war, public opinion over to the Allies. This was way more serious stuff. It did
asciilifeform: Brinkley in... the Brinkley Act, still vigorously enforced today, banning any cross-border studio-transmitter links originating in the US, including Doc's phone lines. From this point on, border blasters had do do it all from their side. A Mexican station was run off the air for this as recently as the 1990s.'
asciilifeform: ( tldr : mexico in 1940s had no radio gestapo. this was used by folx in usa to circumvent the fcc racket, until quashed by fdr decree. )

asciilifeform: this is pretty neat, diana_coman
diana_coman: :) thanks asciilifeform ; and once again a big thank you for carving out that mpi part - it helped a LOT
diana_coman: I gotta run now for a few hours but I'll be back later if there are any obs/comments on it

asciilifeform: plz consider posting your test harness, diana_coman
diana_coman: hmm, I'll check again all the way; at a first look it is as stated but will look and get back on this
diana_coman: makes sense to post the code too though it'll end up in that annoying cycle of versioning since it's far from any final state
asciilifeform: 1+ sec is moar in ffa ballpark than heathentron's
asciilifeform: do what asciilifeform does, post barbaric paste.
mod6: diana_coman: nice write up!
asciilifeform: aha, quality
asciilifeform: ( though i would very much like to see how the seemingly backward decrypt/encrypt time cost diff came about )
asciilifeform: >> http://wotpaste.cascadianhacker.com/pastes/DrA3R/?raw=true << for n00bs : rsa-cum-crt , as seen in koch's gpg-1.4.10
asciilifeform: i.e. you get a speedup on seekrit-op modexp ( but not on public-op modexp ) because you know p and q .
asciilifeform: now perhaps diana_coman replaced the thing with mpi_powm( output, input, skey->d, skey->n ) or equiv. -- but then speed of encrypt and decrypt ought to be ~equal~
asciilifeform: so i have nfi
asciilifeform: also the expected speedup from crt is ~4-fold, not 100-fold...

asciilifeform: diana_coman: does it make sense why asciilifeform went 'wtf, backward' /
asciilifeform: ?
diana_coman: asciilifeform, yes, it does; hence my going "I have to comb this all way through again"
diana_coman: will see if I screwed it up entirely or what
asciilifeform: diana_coman: if you paste it i can prolly say immediately where.
asciilifeform: oh hey look who wasn't eaten!

diana_coman: hmm
BingoBoingo: asciilifeform: Have you tried talking to a few meters of audio track?

mircea_popescu: o hai.
BingoBoingo: o hai
asciilifeform: ohai mircea_popescu !
asciilifeform: diana_coman: this looks almost virginal, the oddity is prolly in wherever you invoke it
mircea_popescu proceeds to logs.

mircea_popescu: it was a whole subculture, you'd try and talk to people then send postcards as a sort of early deedbotting
diana_coman: well yes, basically at rsa stage all I had to change was at generating keys aka source of random bits; the rest was just identifying the relevant parts and nothing more
asciilifeform: mircea_popescu: this tradition still lives, with the postcards
mircea_popescu: ah ? i'd have expected early internet victim
asciilifeform: 'hamism' is a land apart from time, nearly.
asciilifeform: frozen in amber.
mircea_popescu: where was that part about "frozen diff bits of original lang"
BingoBoingo: Hamster even conveniently put call sign on RV license plate

a111: Logged on 2017-11-01 16:21 asciilifeform: asciilifeform finds it more than a little puzzling how little of past 30y of cheap cpu, has been put to use in advancing illicit radio -- where is the dc-to-daylight cryptospreadspectrum pirate ? why idjits still on fixed frequencies, like it were 1930s today ?
a111: Logged on 2017-06-20 16:30 phf: scussions, but also any kind of attempt at crypto communication. there was nothing to say all along.
BingoBoingo: diana_coman: Immigrant snakes in Florida will die swallowing alligators, but haven't seen anything about crocs
mircea_popescu: we're ~the first group with something to actually say.
mircea_popescu: diana_coman crocodile is too fast for snake.
mircea_popescu: i know it doesn't look it, but, crocodile is one of the fastest predators ; apex predator everywhere it exists.
diana_coman: BingoBoingo, interesting; do alligators survive that though?
shinohai: In other "Encryption is for terrorists" news: http://archive.is/zx5WL
mircea_popescu: whereas the only sort of snake that'd bother it even conceivably is constrictor ; definitionally slow.
BingoBoingo: diana_coman: I don't recall.
diana_coman: mircea_popescu,I know it to be uber-fast in water; dunno on land; either way, never saw one in its habitat
mircea_popescu: they lurch see.
asciilifeform: diana_coman: didja actually verify the decryptions' equality to the original input to encrypt ?
diana_coman: yes but after recording the time
diana_coman: I even have those in a file too (i.e. each run, data, encrypted, decrypted
asciilifeform: because i see a public_rsa(out1, msg, &pkey) but then a secret_rsa( out2, out1, skey )
diana_coman: honestly, it's prolly faster to go through it again and then post it all and then take it from there
diana_coman: yes, msg is original data; out1 is encrypted; out2 is decrypted
mircea_popescu: now on the other hand, BABY crocodiles are universally fodder, birds eat them, fish eat them. huge infant mortality among crocs.
asciilifeform: whereas declared as void public_rsa(MPI output, MPI input, RSA_public_key *pkey ) and void secret_rsa(MPI output, MPI input, RSA_secret_key *skey )
asciilifeform: i.e. both take ptr
diana_coman: ah, yes, that's just because the public key is a local var filled with the stuff from private
diana_coman: the private thing basically holds anything anyway
asciilifeform: hm ok
diana_coman: lemme just cut the fluff and then will post
asciilifeform: what's clock()
diana_coman: c function from time.h
diana_coman: cpu clock ticks supposedly
asciilifeform: uhoh
diana_coman: from the post: Durations are given as CPU time in seconds, as reported by the clock() function (time.h) and calculated as ( (double) (end – start) ) / CLOCKS_PER_SEC where end is the value returned by clock() right before starting the RSA operation and end() is the value returned by clock() right after returning from the RSA operation
asciilifeform: yes well
asciilifeform: on some boxes the output for short intervals is essentially random
diana_coman: uhm; what do you suggest I use?
asciilifeform: http://man7.org/linux/man-pages/man2/clock_gettime.2.html theoretically
asciilifeform: but i still have the feeling that this is red herring
diana_coman: hm, I'd be surprised if it gets wildly different results but that would be in itself something...interesting I guess
asciilifeform: diana_coman: is out1 perchance ever equal to out2 ?
asciilifeform: ( same buffer )
mod6: do you have metrics from a baseline of an unaltered gpgtron?
mod6: could then compare your results to that and see.
diana_coman: mod6, I couldn't find some that are directly comparable aka only the rsa ops as such
asciilifeform: mod6: what diana_coman has is as close as fathomable to a virginal gpg where you can still make such a test
diana_coman: asciilifeform, they are not; moreover the log shows clearly that encrypted stuff is different basically
diana_coman: encrypted being out1
asciilifeform: diana_coman: aite. you will notice that public_rsa mallocs if it finds that the output buffer is same as input
diana_coman: yes, I know
danielpbarron: !~later tell BingoBoingo http://wotpaste.cascadianhacker.com/pastes/JDAx6/?raw=true
jhvh1: danielpbarron: The operation succeeded.
asciilifeform: diana_coman: quite a puzzler then: all of the most obvious mistakes, ruled out
asciilifeform: diana_coman: to rule out timer artifacts, can make item that, e.g., carries out 1,000 decrypts, timed with ordinary unix time cmd; then same where 1,000 encrypts
asciilifeform: this is relatively insensitive to clock precision
diana_coman: asciilifeform, possibly I managed to screw it up in an even more basic way; here's the test function itself (this one gets called repeatedly for each key and each message)
diana_coman: http://wotpaste.cascadianhacker.com/pastes/AaM6D/?raw=true
asciilifeform: uh
asciilifeform: pkey.n = skey->n;
asciilifeform: pkey.e = skey->e;
asciilifeform: i am more than a little bit surprised that this didn't bomb
diana_coman: hm, I looked at it and it did not; but let's check
diana_coman: with a proper copy
asciilifeform: and msg is always zero ?!
asciilifeform: or hm nm
diana_coman: no, it's not
asciilifeform: aha i see it
asciilifeform: i see no obvious explanation for the oddity...
mircea_popescu: http://btcbase.org/log/2017-11-01#1731745 << ok, but don't count republican accounting in fiatola ; yes you have an underprotection clause, but it's an ancillary, beloings in a footnote. ☝︎

mircea_popescu: don't worry about it, trial and error, i'll ask questions until i'm out.
mircea_popescu: you keep redoing lol
diana_coman: so, changed those 2 lines to pkey.n = mpi_copy(skey->n) and pkey.e = mpi_copy(skey->e) ; correct?
BingoBoingo: danielpbarron: ty I'll get to your message when physical plant allows
BingoBoingo: mircea_popescu: Ah, ty.
diana_coman: so far results similar in any case aka using public still 0.01... while private afterwards 1.0...
asciilifeform: brainmelting
asciilifeform: prolly time for gprof.
mircea_popescu: did you two run into a fucking portability issue of all things ?
BingoBoingo: brb, mains!
asciilifeform: mircea_popescu: nobody yet knows.
diana_coman: mircea_popescu, so far the ~only part iffy is perhaps choice of timer basically
mircea_popescu: diana_coman do you have something idiotic like say ntp correcting your clock mid-stride maybe ?
mircea_popescu strawpulling
diana_coman: but in a few hours I'll have more uninterrupted time on my hands and I'll be able to go a bit deeper into it
asciilifeform: !!up apeloyee
deedbot: apeloyee voiced for 30 minutes.
apeloyee: asciilifeform: don't be silly, the discrepancy is due to using low public exponent

mircea_popescu: asciilifeform dafuq is anything else. what, you understand "transhumanism" but not "dfhgkerjhtkr" ?
mircea_popescu: they're words they use.
asciilifeform: diana_coman: i wrongly assumed you had fuckgoats output for exponent just same as for key
asciilifeform: because this was in the tentative 'standard' as a variant
asciilifeform: and entirely missed the line in the orig article stating that this was not so...
asciilifeform: mircea_popescu: it's spamology tho, not broken modem, generally there's some consistency neh
mircea_popescu: the rationale is that there ~might~ be some approaches based on pre-established exponents. this is vague, but still, why magic number.
mircea_popescu: asciilifeform i have not yet managed to find the 1 ton of earthworms required to put through the blenders so as to extract the definition of any of these nuts' terms.
asciilifeform: mircea_popescu: cables also work well in another context: cuckolding. if you know what yer doing you can ride signal on top of , e.g., cable tv lines, or whatever derperies of the landscape
mircea_popescu: the advantage of small batshit cults is that there's not enough of them to discover where they self-contradict.
asciilifeform: mircea_popescu: in ffa world, you don't lose anything by using a W-bit prime for the public exponent.
mircea_popescu: (kinda why historically these were "secrets", from eleusis to scientology. the less material, the easier the complexity load)
mircea_popescu: asciilifeform no, i know. from the pov of rsa-being-attacked, it's probably better to have non-standard exponent than "everyone uses 65537"
asciilifeform: aha, and the wider, the better.
mircea_popescu: but this is nothing i can prove in any degree of particuliar.
asciilifeform: the only thing you can prove is that it dun cost you nuffin.
mircea_popescu: this, yes.
asciilifeform: ( other than the basic cost of using ffa )
diana_coman: asciilifeform, guess my next run will have to be with an fg-generated exponent as well; it's not a big deal to add that now; but this was very first run of the very minimal thing
asciilifeform: diana_coman: i expect that you will find the expected 4:1 result then.
mircea_popescu: yee.
asciilifeform: it will be very interesting if not.
diana_coman: <mircea_popescu> asciilifeform no, i know. from the pov of rsa-being-attacked, it's probably better to have non-standard exponent than "everyone uses 65537" <- this
mircea_popescu: also it will have the interesting side effect of exposinbg the shit quality of the imperial hardware/software stacks whenever they try to use our keypairs.
asciilifeform: diana_coman: the folx with custom rsa-bruting silicon , i expect are pissing themselves as we speak
mircea_popescu: i expect a full half of extant rsatrons simply crash if exponent 1kbit
asciilifeform: mircea_popescu: at the very least they will sit around mallocing for a good spell
apeloyee: fwiw, I understand "transhumanist" as "fantasising about entities which are non-human except in the ways dear to me (which in practice will mean they're either impossible or are just broken humans)" work?
mircea_popescu: apeloyee but does this heuristic pass your own criteria for what a definition is ?
asciilifeform: apeloyee: as i understand it was originally 'what if we had memory implants' etc.
mircea_popescu: i also have a vague sense of which categories of psychogenic noise are involved, but...
asciilifeform: bastard child of 'intelligence amplification' as imagined in 1970s, when 'computer won't suck' was still possible to easily contemplate
mircea_popescu: a perfectly valid alt-approach would be to say "transhumanist" is how the new generation of idiots (that call themselves socialists) call "the new man".
mircea_popescu: lenin, also "transhumanist"
apeloyee: not really, but then fantasies don't need rigorous definition
mircea_popescu: actually, fantasies are rigorously defined, yes.
mircea_popescu: there's such a thing as a classification of insanity loci.
asciilifeform: fantasies of stupid folx tend to resolve to some simple combo of physiological hungers being satisfied
asciilifeform: ( iirc mircea_popescu had a piece re subj )
asciilifeform: apeloyee: upstack, it becomes clear that koch put in crt strictly so that gpg can shit out your private key when uncorrected memory flip
asciilifeform: because that's the only thing it accomplishes here
apeloyee: but you ripped asm, which gpg would usually use, no?
apeloyee: *ripped out
asciilifeform: i did. however this affects both priv and pub op equally
apeloyee: would need to check the no-crt version
asciilifeform: pretty easy to do, flip the 0 to 1 in the quoted snippet.
asciilifeform: ( incidentally there will be no crtism in ffa . )
asciilifeform: though i suppose if someone wants to write pcode for a crtistic rsa, i cannot stop him

asciilifeform: (that is, naive gcd with muxed output rather than the ordinary conditional termination)
apeloyee: the division in ffa is slow
apeloyee: that's why
asciilifeform: btw iirc at one time apeloyee posted a newtonian divider, using secretbitcount and secretshift, but the paste got gc'd and it seems i dun have a copy...
asciilifeform prolly oughta set up a perlism to fetch all pastes and save locally, because this is getting ridiculous
apeloyee: it was only an idea for the same, not actual description
asciilifeform: idea is ok.
asciilifeform: i suspect that 'naive' gcd with newtonian divider will be goodenuff speedwise.
apeloyee: my copies of stuff I pasted only has a header entitled "1. Reciprocal calculation by Newton's method", but no content
asciilifeform: ugh
asciilifeform: fortunately mr newton wrote it down...
asciilifeform: in other impressive-if-true tech, http://hflink.com/olivia >> 'Olivia is one of the most robust methods of text keyboarding, that can perform superbly for long distance communications in ionospheric noise conditions where other modes fail. It is possible to communicate worldwide using Olivia with as little as a few watts of transmitter power... Olivia is different from some other types of amateur radio digital keyboarding methods, be

asciilifeform: multi-year thing.
asciilifeform: every once in a while i find the dessicated corpses of folx who were doing evidently ~same thing i was.
apeloyee: one reason those seem impressive is that classical analog modes are so inefficient.
asciilifeform: indeed
apeloyee: \read condition of shannon's noisy channel coding theorem, compare with what clssic modes do, and weep.
asciilifeform: ideally what one'd like is item that is not physically distinguishable from thermal noise to anyone without the key.
apeloyee: needs more wide spectrum
apeloyee: that that olivia thing
asciilifeform: can't be too wide or you get propagation (and multipath) problems
asciilifeform: most of spectrum is not esp. desirable real estate if you want 1000s of km through air
apeloyee: you will have to deal with multipath . narrow spectrum modes is just pretending problem doesn't exist, they just stop working on destructive interference ☟︎
asciilifeform: can deal with it same as with everything else, by lubycode-cum-rsa (i.e. distiller of signal from noise , followed by authenticator )
apeloyee: if you accept ~ minute latency, perharps.
asciilifeform: days is ok.
asciilifeform: the q remains of how one might hide a 100kW transmission from hitler. 1 possible method is to mimic the noise of a natural phenomenon, like lightning strike.
