asciilifeform: PeterL: mircea_popescu's original suggestion was to transfer properly random messages, via rsa, continuously, thereby keeping a supply of otp warm on both sides
asciilifeform: no one suggested reusing an otp !!
PeterL: would be better than just reusing the one otp over a bunch of times?
mircea_popescu: basic cryptoquestion i do not expect an answer to : is there a way to evaluate strength loss by hash pass in a scheme where otp is hashed and the hash used as next pass otp, for N passes of this ?
asciilifeform: not really, given that mircea_popescu already solved this problem in his article by describing 'otp pool'
mircea_popescu: currently the "what happens past key generation" and "there's an otp" part is left pretty loophole-y

asciilifeform: fabio__: the only cryptosystem for which any rigorous analysis exists is vernam (otp).

asciilifeform: otp is the ~only~ thing that ~provably~ worx.
a111: Logged on 2016-07-17 22:00 mircea_popescu: it is not clear that otp actually works ; it is almost certain nothing else in the "pfs" gargle does.

asciilifeform: and, if endpoints know one another in the flesh, otp.

asciilifeform: the otp thread?
trinque: I crap out an encrypted OTP
mircea_popescu: at the USER end. if you want to otp the stuff you put through cs/rsa, by all means.
mircea_popescu: asciilifeform the problems with otp aren't exactly bandwidth like that.
asciilifeform: consider the lengths that were gone to, in order to keep folks using rotors after vernam (otp) was a thing.
asciilifeform: essentially the Big Dirty Secret re crypto is that NO ONE HAS YET proven that non-otp cryptography ~actually exists~
asciilifeform: it is that using ANY system other than otp moves some nonzero qty of info re plaintext with the ciphertext.
asciilifeform: and it isn't 'reveals re otp link'
trinque: obviously using the cramer shoup link is higher risk than the otp one
trinque: what does me moving a cramer shoup key over an otp link reveal about the otp link
asciilifeform: y'know, otp, where a bit of ciphertext conveys 0 BITS OF INFO re corresponding (or any other) bit of plaintext.
asciilifeform: trinque: do you understand the point of otp ?
trinque: asciilifeform: not really. if you wanted to move more data, could exchange pubkeys over the otp link.
asciilifeform: and can anyone suggest good reason why a p2p link between two permanent stations ought to be anything other than otp ?
asciilifeform: CONTIGUOUS DAYS at 9600 baud, on 1TB disk of otp.
asciilifeform: the only genuine 'can solve in ANY way' is in otp.
asciilifeform: or otp.
asciilifeform: this is again true of any system that isn't otp.
asciilifeform: in ANY case other than otp, you have something to solve.
asciilifeform: all roadz lead to otp.
asciilifeform: and you have reinvented otp !!

asciilifeform: (an no this has not been done for any extant system other than otp)
asciilifeform: note that otp is unbreakable even in ~this~ case.)
asciilifeform: (not that otp is unbreakable even in ~this~ case.)
asciilifeform: all we have is a) otp, trivially proven to be impenetrable, high school level exercise b) everything else, being snake oils of varying degrees of toxicity, with c-s being the least noxious known to me presently.
asciilifeform: not a single symmetric cipher other than otp has ever been proven to be worth a sparrow's fart. ☟︎
asciilifeform: Framedragger: you weren't here for the 'symmetric crypto other than otp is snake oil' thread. get thee to the logz.

davout: also looks like there's an extra white space at the end of the GPG decrypted OTP
davout: trinque: looks like deedbot still chokes on trailing whitespace when $v'ing one's otp
