mircea_popescu: and so
the proposition here is
that WHILE rsa encryption does not leak bits, nevertheless rsa signing does ?
mircea_popescu: so, you publish a number S, and a pubkey P.
the verification consists of doing S ^ P.e and checking
that it is equal
to
the hash of
the proposed message mod P.N
mircea_popescu: let us consider
the proper signature scheme for a moment here ?
mircea_popescu: this is
the wrong side of
the exponential and i dun wanna eat it.
mircea_popescu: if you leak bits fix
the leak don't make
the pipe
thicker eh.
mircea_popescu: but
the argument for "4096 is not enough" can not be constructed.
mircea_popescu: the argument for not using 2048 is already very far fetched ("but what if someone makes a computer
the size of our galaxy, WHAT
THEN!)
mircea_popescu: asciilifeform yes, but still
twice
the work, however space-time negotiated.
mircea_popescu: in exchange you get
two
things : you get 2x
the size of message blocks (an advantage
that is actually a disadvantage as now you're using 1kb udp packets which is i expect margionalkly worse
than 2 512s) ; and you get a harder rsa (an advantage which is no sort of advantage,
the 4096 rsa is already harder
than
the extant universe)
BingoBoingo: <mircea_popescu>
that's like... 100 days sorta
thing ? why exactly, have
they decided
the whole
thing coming out of
the previous attempts was
the brief interval of "confusion" before being stomped and so
trying
to maximize
that ? <<
This is Barry Sillybert's stunt
mircea_popescu: and specifically re 8192 : if you use
that, all
the crypto operations
take
twice as long.
this is a certain cost.
a111: Logged on 2017-08-16 16:03 mod6: my question is
then; with regards
to
the
tmsr-rsa rough-sketch spec, do we
then entertain
the idea of other key-lengths, no just 4096 as currently outlined?
mircea_popescu: so : yes, personal hygiene better
than periodic holocaust. nevertheless, personal hygiene gotta be done personally whereas "niste copii au venit de la alt bloc" can do
the holocausting.

mircea_popescu: valica make yourself a pgp key if you don't have one an' register it with deedbot so i don't have
to keep voicing oyu
mircea_popescu: damn... hey asciilifeform wtf was
that article explaining
the problem of socializing
the costs of communication by never providing negative reinforcement ?
mircea_popescu:
http://btcbase.org/log/2017-08-16#1698837 << in
this, as in all cases. except periodic hygiene means
taking woman's baby and crushing its skull against a rock now and again. which is
to say : hygiene cost is personal, culling cost is socialized. guess what "individual" "agents" are going
to choose ? (support material :
☝︎ mircea_popescu: "for
the rabbi, whole world is
torah. for
the ewe however, whole world is grass."
mircea_popescu: "you wouldn't download a car ?" "why not ?!?!" "because nobody made one" "oh... i guess gotta wait
then."
mircea_popescu: makes you wonder how openssl was written in
the first place, seeing how
they had no openssl at
the
time.
mircea_popescu: it's mindboggling, you know ? "run openssl" "and if i don't have it ?" "download it
then!" "And if i'm on a deserted island ?" "well
then you can't crypto!" "sa moara ma-ta ?"

the problem is not
that it's not perfect. it is not perfectible. what you learn
through
this approach is how
to never learn crypto.
shinohai: Article in NY
Times
today says black person responsible for
the creation of Jack Daniels, leaving me
to wonder how long before it starts showing up in rap videos.
ben_vulpes: asciilifeform: hey does
that one have a face?
lobbes: trinque, lol. "Thats it, we're sending you lot
to Mengele's Margaritaville! Its got, yknow, swastica napkins and shit. "
mircea_popescu: when i was about six or so, visiting some relatives who had a farm, i discovered a romanian bareneck (kind of chicken) chick drowning in
the sty efflux. so i picked it out, and it was a pet for a year or so and
then made a great soup. rooster,
too.
☟︎☟︎ mircea_popescu: no, i want
to discern whether
the guy is a working mind accidentally stuck in
the swamp of nonsense, or actually belongs
there.
mircea_popescu: basically
they're mostly
trying
to use python
to write makefiles in
the manner naggum self-reportedly used lisp
to write c.
mircea_popescu: if he has enough sense
to google his name he'll see it anyway.
mircea_popescu: asciilifeform python,
the republic's preferred webdesign postprocessor ?
mircea_popescu: valica_ feel free
to link
this convo
to mr. choudary btw.
tell him i have some
things
to say
to him.
a111: Logged on 2017-08-16 17:13 mircea_popescu: "your job is
to fill in
this merkle.py". holy mother of god.
valica_: i know some math students interested in crypto, one of
them worked in a call center
mircea_popescu: i suppose
the item rolls back
to "i wouldn't
teach crypto, i'd have
to fix undergrad first, get some kids who can do a fucking lim"
valica_: we can
talk more on
this subject, privately sometime
mircea_popescu: valica_ i would
teach crypto as a graduate level item for
the
top of
the class in math and kids from physics who
test in. and nobody else.
mircea_popescu 's unformal education in
the field nevertheless does include
the "suprareal" class at avram iancu highschool, which did include gavra's classes on number
theory or participation at mme popoviciu's "itinerant seminary on functionals, approximations and convexity" and so on and so forth.
valica_: how would you
teach crypto
then?
mircea_popescu: valica_
the problem is not
that it's not perfect. it is not perfectible. what you learn
through
this approach is how
to never learn crypto.
☟︎☟︎ mircea_popescu: (for
the lulz record :
that coudary fellow actually has a cambridge phd.)
valica_: :) it's just some easy
task
to force you
to
type "man openssl"
mircea_popescu: what
the fuck is ADVANCED about
this windows-user-level intro
to "which button
to cluck at" ?
mircea_popescu: valica_ i suppose
this is a fine approach for orc unis, pay some local a few benjies
to sit around with
the chitlins while
they read wikipedia. it
took 20 years
to progress from calling it an internet cafe
to calling it a "lab"
trinque: I'm sure
the jimmy buffet nazis will stop
them, lobbes
mircea_popescu: yes, but when school's not over, who ie what professor is
the lead of
this cryptography line ? what's it actually called ?
mircea_popescu: what do you mean by formal ? "at college" sorta
thing ?
