asciilifeform: what prevents ?

asciilifeform: the thing i do not understand is, how does the thing not fork? say i fire up a prbtron and prbsend to A. then fire up trbtron and send same coin to B. ☟︎

asciilifeform: does it thereby follow that prb and trb have differing notions of how much coin is contained in A ?

asciilifeform: say i use prb to send C coin to addr A, via some strange method that results in ben_vulpes 'unable to decode'

asciilifeform: i don't grasp how this kind of thing can work without being a hardfork ☟︎

asciilifeform: i see quite a few of these.

asciilifeform: ben_vulpes: what means 'Unable to decode destination address.' , http://mimisbrunnr.cascadianhacker.com/blocks?height=432901 ?

asciilifeform: Believe Moar Promisetronics

asciilifeform: http://btcbase.org/log/2016-10-05#1553054 << lol shitphone ☝︎

asciilifeform: aah.

asciilifeform: ...

asciilifeform: !!deed http://wotpaste.cascadianhacker.com/pastes/a4dq0/?raw=true

asciilifeform: but that was in '12.

asciilifeform: last i checked, they did not

asciilifeform: ( does nvidia sign ? )

asciilifeform: and whatever other interesting fritz keys.

asciilifeform: nooow somebody gotta do the intel turds.

asciilifeform: (modified version thereof pasted earlier.)

asciilifeform: kudos to jurov for the generator.

asciilifeform: and to think, none of this was even on my original plate for today.

asciilifeform: make all of'em.

asciilifeform: all 8 in.

asciilifeform prepares to push button

asciilifeform: aaaaaaaaand...

asciilifeform: not yet

asciilifeform: about to fire.

asciilifeform: http://wotpaste.cascadianhacker.com/pastes/yg2lx/?raw=true

asciilifeform: aaaaaaaaaaaaaand

asciilifeform: rectothermoscope.

asciilifeform: these tend to come in when we have threads like earlier.

asciilifeform: in other hilarities, i pick up the phone, and it is yet moar unsolicited work offers from usg.

asciilifeform: ( if only i had these last year ... )

asciilifeform: earlier he sent me complete symbol tables for the sage rom.

asciilifeform: thank you for your finds, kmalkki . please come back, and make pgp key

asciilifeform: anyway about to try jurov's.

asciilifeform: and neato.

asciilifeform: oh huh, possibly jurov's thing will work

asciilifeform: well, i pinged him earlier (seems like we lost ;;later tell ...) so perhaps he will show up soon.

asciilifeform: (phuctor is very deeply baked around rfc4880 and expects all db entries to parse by it, and changing this would be a titanic labour)

asciilifeform: which i can't seem to find a copy of

asciilifeform: only via Framedragger's script

asciilifeform: mircea_popescu et al ^ .

asciilifeform: ok these then all become sane-looking rsa moduli.

asciilifeform: no but if it follows same pattern as the exponent

asciilifeform: that would make sense

asciilifeform: hm

asciilifeform: (conceivably the cheapest way to read out the boot rom would be to get arbitrary code execution in the stock turdlet)

asciilifeform: kmalkki: also interestingly, the turdlets are supposedly arm-compatible, and - to naked eye, seeing strings - plainly unciphered, but they do not appear to disassemble cleanly as either big- or little-endian arm.

asciilifeform: all but the last is littleendian-even.

asciilifeform: !!up kmalkki

asciilifeform: *going

asciilifeform: does anyone see where this is goign

asciilifeform: they parse.

asciilifeform: yes, the parsed-out mods.

asciilifeform: incidentally, the moduli in the self-signed blobs end in : d6 e1 1c ec ; 46 0a d0 9a ; be fe 39 b6 ; 2c c3 f2 a2 ; 46 0a d0 9a ; 13 7d e7 c3 .

asciilifeform: i am not a wealthy man, mircea_popescu .

asciilifeform: nor dirigible.

asciilifeform: mircea_popescu: plenty, but no electron microscope.

asciilifeform: where the actual verification routine lives

asciilifeform: kmalkki: do you know whether anyone has read out the mask rom ?

asciilifeform: (and if it did not, i still don't see how glomming bits onto the payload would change the outcome of the verification)

asciilifeform: thing hashes a fixed-length turd, it would seem.

asciilifeform: yes, but does not help in this case

asciilifeform: aha.

asciilifeform: though if it really has an even N...

asciilifeform: but i bet that it'd happily eat a collided turd

asciilifeform: kmalkki: this would not be a surprising way to do it - sha is easy to hardwareize, rsa - not so easy

asciilifeform: and - unless i am hallucinating - has an even N

asciilifeform: nor any checksums, it would appear.

asciilifeform: the master key, interestingly, has no self-sig.

asciilifeform: as kmalkki pointed out earlier.

asciilifeform: that next one has a selfsig

asciilifeform: nono

asciilifeform: i.e. little-endian.

asciilifeform: observe that the exponents are 01 00 01 00 00 .......

asciilifeform: 0xcc == 0b11001100 .

asciilifeform: cc df 66 cf littleendianized

asciilifeform: http://btcbase.org/log/2016-10-04#1552874 << evidently not, they are not functions of the exponent or modulus (they stay constant across variations in both of the latter) ☝︎

asciilifeform: otherwise, in the case of the 1st one seen here, http://wotpaste.cascadianhacker.com/pastes/wv3x3/?raw=true , it would be even?!

asciilifeform: kmalkki: this would suggest that the modulus is stored big-endian ?!

asciilifeform: in python, gives (little-endian) extracts of exp and mod.

asciilifeform: mod = blob[0x40 + exp_size : 0x40 + exp_size + mod_size]

asciilifeform: exp = blob[0x40 : 0x40 + exp_size]

asciilifeform: mod_size /= 8

asciilifeform: exp_size /= 8

asciilifeform: (exp_size, mod_size) = struct.unpack_from("<II", blob, 0x38)

asciilifeform: blob = open(sys.argv[1], 'rb').read()

asciilifeform: ok, so,

asciilifeform: !!up kmalkki

asciilifeform: they are constant for each blobset.
