asciilifeform: we had dmso thread, sure

asciilifeform: and afaik there was not

asciilifeform: BingoBoingo: if dmso, there'd be a dead medic or two

asciilifeform: perhaps mircea_popescu can think of one.

asciilifeform: fwiw i am unaware of a poison where (supposing it was strictly wet-rag delivery) you get this.

asciilifeform: ^ this rumour is interesting to asciilifeform because he is unaware of any poison that fits this description that would not equally endanger the wielder

asciilifeform: liquid", Fadzil Ahmat told Bernama, and he died on the way to hospital in nearby Putrajaya.'

asciilifeform: 'Malaysian police official Fadzil Ahmat told The Star that Mr Kim had alerted a receptionist, saying "someone had grabbed him from behind and splashed a liquid on his face". But quoted by Malaysian news agency Bernama, the same official said a woman had come at him from behind and "covered his face with a cloth laced with a liquid". Earlier reports spoke of a "spray" being used or a needle. His eyes "suffered burns as a result of the

asciilifeform: '"President Trump has made it very clear that he expects the Russian government to de-escalate violence in the Ukraine and return Crimea," Spicer said at the daily news briefing on Tuesday. “At the same time, he fully expects to – and wants to – get along with Russia."'

asciilifeform: in other lulz, 'US President Donald Trump has been tough on Russia and expects Moscow to “return” the Crimea peninsula to Ukraine, the White House spokesman told reporters.'

asciilifeform: the good news is that you can stack up as many rng as you like...

asciilifeform: there is no limit to the parallelization (it is exactly (bytes in paylod)/(the block size of the cipher) threads ) but you cannot generate a new ciphertext any faster than your rng will give it to you.

asciilifeform: and you are also limited now to its bit rate.

asciilifeform: at least one of the losses, however, is that you now need a serious rng on the transmitter.

asciilifeform: so the win is, since you dispense with feedback, you can parallelize encipher and decipher, blockwise.

asciilifeform: right, but this is not normally where 'padding' is used. but yes.

asciilifeform: each block ciphrator is now eating what is individually a trng stream.

asciilifeform: without chaining the blockcipher's blocks

asciilifeform: what we've done here is to destroy the structure of the penguin

asciilifeform: to get the original payload.

asciilifeform: mircea_popescu: you do this every time, after you decrypt the x- and y- blocks.

asciilifeform: you encipher the x1,x2,.....x_n with one key, and the y1,y2...y_n with another.

asciilifeform: specifically, for every byte you intend to send, you instead send two: x, y. which you generate by obtaining rng byte r, and payload byte b, and x := b xor r, y := r ☟︎☟︎☟︎☟︎

asciilifeform: i found that one. but i thought there was also another where i suggested a sideways cut of the knot

asciilifeform: mircea_popescu: i've been digging for the thread where we discussed CFB ('cipher block chaining'), the infamous penguin, etc. but could not find
