shinohai: !~later tell spyked got a question regarding the w3m patch when you have a sec.
jhvh1: shinohai: The operation succeeded.
spyked: morning, shinohai
shinohai: Heya spyked, was looking at your patch last night .... where did you get your w3m source code from if I may ask?
shinohai: https://www.digitaltrends.com/cool-tech/lava-lamps-encryption/ <<< in other faux phuctors (page refuses to archive for me)
spyked: shinohai, sourceforge, unfortunately (w3m devs still host it there for some reason). exact link: https://downloads.sourceforge.net/w3m/w3m-0.5.3.tar.gz same for the njs library; one sec, I'll look it up
shinohai: Its ok spyked .... this is the one I tried, albeit in a Debian VM. ./configure keeps failing for me saying there is no gc
shinohai: though it is available, I'm puzzled. (Your patch did apply cleanly)
spyked: ah crap. yes, I installed the gc lib from the debian repo. I don't know why they removed gc from the w3m tree
shinohai: Hmmm .... I have the gc repo though, still fails.
spyked: that's odd. can you paste somewhere?
spyked: the configure/make output, that is
spyked: shinohai, I remember getting this as well at some point. can you also paste config.log? the js library bits that I added to ./configure are very hack-ish (IMHO the thing shouldn't be dynamically linked anyway, so I just hacked through it to make it work)
shinohai: Just an aside, I *also* tried this unpatched and get same error. One sec, posting config.log
spyked: (ftr, libgc is why I rebased the patch on w3m-0.5.3 in the first place; for some reason the "mktable" executable generated by w3m was segfaulting in the gc library, while I knew 0.5.3 compiled on my system before, with libgc from debian sources)
shinohai: I know I have builit it plenty of times, I'm trying to remember if there was some patch for that, don't recall
shinohai: ( I think I used this version tbh https://github.com/tats/w3m ... I loath sourceforge lol)
spyked: shinohai, I know why the patch fails, though not sure why it fails without it... did you also compile and install libnjs? e.g. on line 1840 in config.log, "cannot find -ljs". hm. I am guessing you should have it installed if w3m-0.4 worked for you.
shinohai: Nope, not available in repos either .... got a sauce?
spyked: the original w3m-js patch adds a -ljs compilation/link-time flag. now, there's another issue: if your libjs is in a path that the run-time linker can't find (e.g. /usr/local/lib as opposed to /usr/lib), it will fail again at some point.
spyked: shinohai, https://sourceforge.net/projects/njs/ (would be cool if there was out of sourceforge link too... /me will have to host all these somewhere publicly at some point)
shinohai: grrrr .... thanx for assistance spyked. I rather like w3m (because inline images) but truly needs a lot of cruft removed and things organised - mainly the sourceforge madness.
spyked: all these libraries (gc + njs + others) can be embedded in the original w3m and made self-contained (including removal of shared library nonsense, like gc was linked in 0.4), but they'll require me 1-2 full days. to put on list
spyked: I like w3m as well. the codebase is surprisingly easy to understand (took me a few hours yesterday to get a vague idea of how modules work together), though I have no idea why they need a gc. links is even more minimal, but I use w3m mainly because it runs in emacs.
shinohai: links is nice, it will at least open images in a framebuffer.
shinohai: bah, weird errors trying to build njs .... this is better left to when I can look at a full cleanup.

diana_coman: asciilifeform, mind expanding a bit on what you had in mind as best way to expand serpent to 512 bits blocks?
diana_coman: and 512 bits key too for that matter
asciilifeform: to expand a K-bit (block and key, we'll assume, are each K-bit) voodoocipher to J bitness, xor split ( on rng ); having generated J / K independent keys; each incoming plaintext block of J bits, is cut into J / K blocks, and each enciphered with the corresponding key. decipher -- same.
asciilifeform: xor split each plaintext block, that is
asciilifeform: actually nm
asciilifeform: this is wrong; and the correct algo is in the l0gz...
asciilifeform: anyway for 512bit key, you still keep the 128bit block. but each time you have incoming 128b plaintext, you shamir it rngistically into 512bits, i.e. 4 128b parcels that must be xor'd to reconstitute the original. each of these get ciphered with one of 4 independently-generated 128b keys.
diana_coman: hm, I probably did not know how to search for it properly as I did look but still not very clear on it
asciilifeform: on the decipherment end, each split gets deciphered with the respective 128b key , and the four parcels xor'd to form the plaintext again.
asciilifeform: does this make sense ?
diana_coman: ah, it was the construction on top you had in mind
asciilifeform: the 1 aspect that historically bothered me, is that enemy knows now a relation between the plaintexts in the 4 streams

asciilifeform: back to the shamir scheme : the only thing i can properly prove about it, is that it isn't weaker than straight single-key-with-no-splits
asciilifeform: and, on top of this, each stream ~individually~ is not distinguishable from rngolade.

a111: Logged on 2017-02-25 21:26 asciilifeform: so, for instance, you can prove that a k-of-k (must have ALL parts) shamir split, where you then take each share and encipher with different method -- will NEVER be weaker than the strongest cipher used.
asciilifeform: you thereby get a 'ratchet'. which afaik is the only hard strength result in all of crypto aside from von neumann's otp proof...
asciilifeform: ( which it is really but a restatement of )

mircea_popescu: http://btcbase.org/log/2017-11-22#1742198 << how about actually using a 512 bit block
a111: Logged on 2017-11-22 21:45 asciilifeform: anyway for 512bit key, you still keep the 128bit block. but each time you have incoming 128b plaintext, you shamir it rngistically into 512bits, i.e. 4 128b parcels that must be xor'd to reconstitute the original. each of these get ciphered with one of 4 independently-generated 128b keys.
asciilifeform: mircea_popescu: serpent isn't defined as a stretchable thing - i.e. it isn't obvious what ought to be changed to produce a larger ( or smaller, for that matter ) block, and still to have it meaningfully similar to original
asciilifeform: rather like the diff b/w sha512 and keccak
asciilifeform: ( the latter is defined as a family of functions, and so 'rubber' )
mircea_popescu: dja see why i'd muchly prefer a native tmsr.rsa length symmetric cypher rather than this nonsense ?
asciilifeform: really not hard to see
mircea_popescu: and why trhe fuck am i using "4 bit permutations"
mircea_popescu: and so on and so on
asciilifeform: it does cost moar tho. even once i'm done with the asm version.
asciilifeform: modular exp is intrinsically costlier , at least on pc iron, than the idjit rotorization used in symmetrics
mircea_popescu: anyway, whatever, diana_coman : the correct implementation approach to patch the 256 bit serpent into 4096 bit rsa is to cut every rsa block into 16 fragments, cipher each independently with diff keys, then paste the 16 keys together make 4096 bit of key.
mircea_popescu: it's bullshit all the way down, "the 4096 bit block gets cut into 16 sub blocks to be fit into rotorizers that cut each block into 64 bits and process with their 4 bit s boxes". because we're from the fucking cartoons.
asciilifeform: sad, innit. asciilifeform for instance has a mtbf of about 1hr when reading about symmetric ciphers. after that -- barf
asciilifeform: because ultimately yes 'down to the 4bit sbox!'
mircea_popescu: asciilifeform i have this itching half-memory that serpent 256 was actually defined
asciilifeform: it was.
asciilifeform: but ~key~ size
asciilifeform: block was fixed at 128bit.
diana_coman: mircea_popescu, 256 key, 128 block
diana_coman: heh, crossed with asciilifeform
mircea_popescu: asciilifeform right you are, it's in the... 2006 spec.
mircea_popescu: in other lulz from same source (ross anderson of cambridge) http://www.cl.cam.ac.uk/~rja14/Papers/tamper.pdf
mircea_popescu: that one from 1998
asciilifeform: classic piece
diana_coman: mircea_popescu, let me see if I got this right re "patch": simply apply serpent as it is and then at the next level up glue x keys together and send as "key", glue the corresponding x outputs together and use as "output"; basically lump together 16 serpents
mircea_popescu: asciilifeform the "specificication" published on cambridge page is most likely a later fake. it's a 2006 item supposedly of a 1998 document.
mircea_popescu: OTHER 1998 documents, of lesser political sensitivity, exist there in original format.
asciilifeform: mircea_popescu: the current serpent www is at the very minimum known to be missing items from before
asciilifeform: so why not also serpent.
asciilifeform: keccak, i meant, turned up missing items
mircea_popescu doesn't recall why we picked up airbase 1 serpent in preference of japanese item ?
mircea_popescu is annoyed.
asciilifeform: y'know the splits dun all have to be ciphered with same scheme
mircea_popescu: asciilifeform dja recall the discssion with apelyobee fellow ? http://btcbase.org/log/2017-11-14#1737658
a111: Logged on 2017-11-14 14:55 mircea_popescu: this is the problem with "complexify the code machine" tendency. somehow it appears intuitively evident that having a portion of the code INSIDE the machine is "a more complex, therefore a more secure system". it is not. 100% of the key belongs in the key.
asciilifeform: i read that line as a restatement of the ancient 'seekrit algos are a stupidity, honest crypto keeps only privkey seekrit' truism
mircea_popescu: diana_coman and of course we end up with 8kb of bs "key" for every 4kb payload don't we.
mircea_popescu: well 256 bit keys 128 bit blocks.
asciilifeform: ah with no splits then yea
mircea_popescu: so basically we'll be reusing serpent keys, is the idea ?
asciilifeform: ( in other 'gangrene ? what gangrene?' horrors : 'LibTomCrypt is pretty nice to read (only bug found in last 10 years was in prime generation — failed to iterate Miller-Rabin)' -- from turd https://comsecuris.com/slides/slides-bignum-bhus2015.pdf re broken bignumatrons. cited line presented as a 'hey it's pretty good'... )
mircea_popescu: check it out, diana_coman has found de-facto work-around to "my theme overwrites text up top" : put an intro in, page or so before code :D
diana_coman: mircea_popescu, aha!
mircea_popescu: anyway, so what's the work mode here, every now and again server sends client a rsa-encrypted packet containing 16 aes keys ; client enciphers its comms to the server with one selected from a set of 8 selected from those 16 ; and deciphers server's with one selected from set of 8 other than previous set. now and again burns a key.
mircea_popescu: when left with two unburned gets new set.
diana_coman: mircea_popescu, aes keys??
mircea_popescu: sorry serpent keys
asciilifeform: dun have to swap ~all~ the keys every time there's an rsagram
mircea_popescu: sed 's/aes/serpent/'
mircea_popescu: asciilifeform client just keeps a list. adds to it when rsagram
mircea_popescu: strikes from it by criteria.
mircea_popescu: this actually seems a rather workable method tbh.
mircea_popescu: allows for very elastic packets / metering of security needs by user.
asciilifeform: iirc this is the scheme asciilifeform originally suggested.
mircea_popescu: diana_coman thereby all game packets will be multiples of 128 bits, and in principle a client can live off the first original rsa op its entire life if it so wishes.
mircea_popescu: asciilifeform pretty cool.
asciilifeform: it costs, however, http://btcbase.org/log/2017-11-22#1742216 .
a111: Logged on 2017-11-22 21:56 asciilifeform: my approach is a universal 'stretcher', predicated on having reasonably fast and high-quality trng.
mircea_popescu: diana_coman i guess we'll define a "control packet" which is always the first 128 bits of every comm, which will contain data such as "killed key #x moved to #y" and also "running out of keys send moar".
mircea_popescu: asciilifeform sorry ?
mircea_popescu: server generates all serpent keys. no stretching .
asciilifeform: actually if client doesn't get to generate keys
asciilifeform: aha right
asciilifeform: if server generates all keys, client dun need an rng at all.
asciilifeform: ( aside from when creating his original rsa priv )
mircea_popescu: the major advantage of which is that user will be able to enjoy security flowing from server even without own fg.
mircea_popescu: and suddenly the fg entropy debit is relevant : eulora server will be capable to produce iirc no more than 64 serpent keys/second per installed FG.
mircea_popescu: in reality less as it draws some itself.
asciilifeform: this is approx correct.
mircea_popescu: so i'm guessing a daily-ish serpent key change per client is not unreasonable.
asciilifeform: would depend on how populous, neh
asciilifeform: with few enough clients, even hourly'd be workable
mircea_popescu: but if memory serves the "attack" on serpent used 2^100 plaintexts sorta deal
mircea_popescu: asciilifeform yes but taking the assumptions other way to see how bad it looks.
mircea_popescu: imo dun look bad at all.
diana_coman: mircea_popescu, 16 serpent keys means 16 keys of 256 bits each?
diana_coman: mircea_popescu, and then when client enciphers with 1 from a set of 8 selected from those 16: does this mean reusing that 1 key for as many 128 chunks that particular eulora message has? or do you mean 1 per chunk ?
mircea_popescu: it means reusing
diana_coman: k, I think I got it
mircea_popescu: in ~principle~ serpent doesn't expose the key anymore than it exposes the cipher. the claim is that if you know about 2^100 or so plaintext-ciphertext matches you can extract the key.
mircea_popescu: now, the expectation is that a full day of play will produce less than say 2^15 or so messages.
diana_coman: myeah, since reading more seriously on crypto I read a LOT of claims, certainly
asciilifeform: diana_coman: there is ~nothing serious printed on the subject publicly since... von neumann
asciilifeform: which is why 'hitting the books' is a very limited proposition. the most that can generally be asked from the dead trees, is an accurate picture of the popular algos, plus details of the most well-known attacks on various (e.g. lenstra's, pollard's, etc )
asciilifeform: but as for the general principles which a naive n00b might hope to find in such a work -- there's nothing since old man john von n.
asciilifeform: ( and , jaw-droppingly, just about every book 'on crypto' omits the otp proof. that very same, that constitutes the alpha and the omega of what's actually proven in the subject at all )
mircea_popescu: hey, every ro "blog" omits mention of trilema.
mircea_popescu: dun look good together.
asciilifeform: exactly same phenomenon imho
asciilifeform: including the otp proof would immediately invite the q, in even a half-awake reader, of why the fuck the rest of the tree had to die
asciilifeform: to produce the brick of nonsense that follows
mircea_popescu: something quite like that.
asciilifeform: in today's gnattronics finds :
asciilifeform: 1 ) build a gnat proj 2) gnatxref -a -aO path_where_your_ali_files_end_up yourmain.adb > xref.txt
asciilifeform: shits forth a concordance, e.g. http://wotpaste.cascadianhacker.com/pastes/MDZMh/?raw=true .
diana_coman: asciilifeform, I suspect it's quite possible that the writer would end up with that q so... no book
asciilifeform: ( full usage/dep topology for every named entity in your proj )
asciilifeform: with lines/columns where used, and where defined.
diana_coman: that being said, whenever I find I don't even have that poor picture as full and as clear as I'd like, I'm still left with little other choice then to go and read; possibly again, what can I do
asciilifeform: diana_coman: the writer is typically a schneier-style wretch who made 'the bargain' and very well knows about otp
asciilifeform: and ain't sayin'.
asciilifeform: diana_coman: aside from von neumann, and the crc encyclopaedia of well-known algos, i cannot in good conscience recommend much reading. there are works devoted to specific known attacks on rsa ( song y. yang, plus a few ru items ) ; at least 1 dead tree on differential cryptoanalysis ( how items like des get trivially demolished ) whose author presently escapes me; and that's just about it
asciilifeform: you're prolly better off reviewing the fundamentals of information theory ( shannon et al )
asciilifeform: asking for 'good books on crypto' is not wholly unlike to ask 'good books in astrology'
diana_coman: eh, 'good books in voodoo', let's not branch un-necessarily :p

mircea_popescu: but this is the fucking "career" of these schmucks. born 83, graduated "college" 2003, worked as a fashion-culture-pop-media "editor" at some obscure local paper, then became "a PR officer!!1" by now pretending to "cultural management". motherfucker. management ?!
mircea_popescu: for the same money could pretend to cultural engineering. which, obviously, they do.
phf: asciilifeform: yeah, i had the same thought until she started speaking, i mean, shit, they don't have "toastmasters" in romania? practice your talk before going in front of people
mircea_popescu: phf it's not that they don't have toastmasters in romania. it's that they don'tr have anything if you're born after 1980.
mircea_popescu: and i mean this most literally.
mircea_popescu: " At Buyerbrain, Ioana performs as a researcher and as a multidisciplinary perspective analyst, disseminating and promoting the neuroscience culture while also applying those principles to marketing and communicating the laboratory." you understand me ?!
mircea_popescu: what fucking toastmasters.
mircea_popescu: the neuroscience fucking culture so help me.
asciilifeform: neuroscience culture..?!
mircea_popescu: apparently what, on the basis of this malfunctioning spam script they also don't have basic logic in romania now ?
mircea_popescu: yeah, that's the entomological value here : that these EXACTLY IDENTICAL fucktards haven't yet heard of THAT fashionable bullshit. so they're still working the old style nonsense. yet the underlying opcodes are very visibly exactly the same.
mircea_popescu: allows for some diffing, "what's this z69 say vs that one ?"
mircea_popescu: and i'll insist and underline that no, can not be the case these are people. if i can emulate 10k of them on a stock amd, they're not people, they're 1/10k of a stock amd.
