zx2c4: well im still around here for another half hour or so, so feel free
to lob anything more at me

that's probably my
thing, I've been playing with it for
the last
two weeks or so, I have it in a loop grabbing feeds from republican blogs.
mircea_popescu:
http://btcbase.org/log/2018-04-12#1796976 << you know me. he doesn't know you.
this makes all
the difference in
the world -- i can whip my slavegirls into shape because
they ~love me~. people without
this benefit are stuck going at snail speed, which is why "education" in
the unsexualized way it's implemented publicly does not work. it couldn't fucking work.
☝︎ mircea_popescu: speaking of which and ben_vulpes boyhood dreams, ssto and so on : i dreamt last night
that someone actually managed
to create
that
true wunderwaffen material,
the composite/ceramic with higher
tensile strength
than steel, but negligible caloric conductivity. making some iiiincredible jet engines.
a111: Logged on 2018-04-12 08:33 ckang: granted im sure
things are progressing, but its hard
to outperform something from a billet of aluminum
a111: Logged on 2018-04-12 08:31 ckang: cant get behind all
this 3d printer fanboy stuff, its just not a good substrate with
the current materials for anything you want
to last somewhat longterm
zx2c4: well, feel free
to keep filling up my wallet, say, with
thousands of coins O_o
mircea_popescu: i
think if you have not enough in your wallet it drops it silently ; and if
the payment's not processed yet you might have nothing in your wallet yet.
zx2c4: i wonder if
that verification worked i just posted
zx2c4: lets see if
that works
mircea_popescu: so it permits indefeasible record of deeds ; something
the fiat sovereigns have not yet managed.
mircea_popescu:
http://deedbot.org/ << on deedbot you can register any arbitrary item ; it keeps a record
that indeed your signature did so ; and it marks
the
time,
through inclusion in
the bitcoin blockchain
mircea_popescu: the deed in deedbot comes from
the republican system for registration of deeds.
think of it as your county clerk, you can go
to him
to register your wedding or business or w/e.
mircea_popescu: this is a lot more
than meets
the eye ; because it actually restructures conversations into a
tree.
things here have a depth not encountered anywhere else.
zx2c4: if you guys wind up using wireguard for part of your infra and want
to support wireguard for a year, i'm always looking for large donations, etc. not sure if
that's what deedbot is for exactly but
that would be quite
the nice deed
mircea_popescu: you can click
the link and see a website-based story of
the log ;
the bot also reads
the line referenced in conversation.
a111: Logged on 2018-04-12 16:32 mircea_popescu: now let's look at
the logs :
mircea_popescu: they are not for you ;
they are for me. deedbot works an otp verification model -- you
tell it
to do whatever youwant, it asks you
to prove you own
the key, if you do it does it.
zx2c4: no, not at all. im also not quite sure what
to do with
these pgp encrypted blobs i cant decrypt
zx2c4: asciilifeform: oh, okay. im happy
to keep going
though. and if you want
to be uncivilized, ill gladly accept any harshness you want
to
throw my way. i dont scare easilyt
zx2c4: mircea_popescu: no,
thought it was quite productive actually
zx2c4: ill
try it in public here instead
zx2c4: i
tried registering my key privately
to deedbot but it didnt respond
zx2c4: seems like lots of
things
these days have
testimonials
zx2c4: i havent compiled a list of Name+WrittenReview. maybe i should do
that
☟︎ zx2c4: and
then since several other colleagues and cryptographers have reviewed
the system favorably
zx2c4: then in
the acknowledgement of
the paper, a few others arementioned who reviewed it while it was being written
zx2c4: i dont
think
they post
the reviews? except
that it was "accepted"
to
the conference
zx2c4: yea usually
there's lots of information on
the conference and board and whatnot
zx2c4: its in a much better place
than just raw md5
zx2c4: i dont
think hmac-md5 is anywhere near broken, actually.
zx2c4: blake2 came from blake which went
through
the sha3 contest as a finalist
zx2c4: but anyway,
the world has learned quite a bit since md5
zx2c4: blake is also faster
than md5 which is nice
zx2c4: similar criteria - well understood, simple
to implement, fast on nearly all hardware
zx2c4: i'd be surprised
to see all 20 rounds of chacha broken
zx2c4: i'm pretty sure
there's no conspiracy
zx2c4: theyre simple and fast on all hardware, and he came up with an api for using
them
that many developers like
to use (the nacl stuff)
zx2c4: are you skeptical of djb primitives? wondering with what motivation came
that question?
zx2c4: seems like
there are many places and interesting ways
to optimize at
this point. lots of neat creative work coming out. but
that with aes and whatnot, we're in a pretty good place in
terms of symmetric crypto
zx2c4: so anyway, im less concerned about symmetric cryptography
than other
things
zx2c4: but even hardness of factoring... how hard is
this actually? what number
theoretic advances are right around
the corner?
☟︎ zx2c4: things like RSA boil down
to number
theory problems. but
that's in a sense scarier
than
the set of problems
that good block ciphers
tend
to boil down
to. because it means
that
those primitives have lots of _structure_, and generally structure is something
that can be exploited. just look at all
the amazing and fantastic attacks on
things with structure. so just boiling down
to a [currently considered] "hard problem" doesn't provide as much solace
☟︎ zx2c4: not anymore
than other
things in cryptography worry me
zx2c4: aes is also well understood, but is neither easy
to implement, simple, nor fast on all hardware
zx2c4: its also easy
to implement and simple
zx2c4: if you're interested in crypto primitives in wireguard in general, i can give you an overview of our implementations.
the hacl and fiat code is not
the only code we have in
there
zx2c4: i dont own any via 2000 hardware
to
test on
zx2c4: if you've found an architecture attack
though, please do publicise it.
that sounds like it could be some really great security attack work.
zx2c4: asciilifeform: i haven't been able
to observe any non-constant
time multiplications on intel in
that code
zx2c4: does
that entitle me
to deedbot btc?
zx2c4: you mean if you just wanted
to hand audit
the .o
that comes out of
this?
zx2c4: ill show you
the code
zx2c4: our discussion of HACL* and fiat-crypto pertains
to
the
two C implementations of x25519
zx2c4: yes,
there are no conditional jumps
zx2c4: by only using a limited subset of constructs which are known
to be constant
time
zx2c4: also, constant
time
