Fri Jun 05 16:03:02 UTC 2015 <assbot> The strange case of the unentropic entropy and other bedtime stories of primes and people. on Trilema - A blog by Mircea Popescu. ... ( http://bit.ly/1H8Xpuk )
Wed Jun 03 16:20:10 UTC 2015 <liquidassets> sometimes I buy a few small things using their interface like a trezor or mycelium entropy
Wed Jun 03 00:07:49 UTC 2015 <williamdunne> Bits of entropy
Tue Jun 02 21:39:13 UTC 2015 <mircea_popescu> "Back when the NSA was routinely weakening commercial cryptography, their favorite technique was reducing the entropy of the random number generator."
Sun May 24 15:07:07 UTC 2015 <mircea_popescu> funkenstein_ generating entropy is not easy, and oyu can already do that as-is.
Sun May 24 15:06:37 UTC 2015 <funkenstein_> is that I could easily generate my own entropy for my keypair
Fri May 22 17:49:34 UTC 2015 <asciilifeform> you'd have to use intervals between spikes as the entropy
Wed May 20 17:10:13 UTC 2015 <Hasimir> no, not seriously, there's a big difference between some bunch of people with crap entropy sources and rsa being borked
Mon May 18 21:34:28 UTC 2015 <mircea_popescu> mxtm it's not a REAL entropy source. it's a defined sequence that may be confused for an entropy source, if one's definition of entropy is test based.
Mon May 18 21:33:45 UTC 2015 <mxtm> Apocalyptic: then how would it be an entropy source
Mon May 18 21:31:43 UTC 2015 <mxtm> why would pi be an entropy source
Mon May 18 21:30:51 UTC 2015 <mircea_popescu> justJanne the application here is that, if i give you a string of random numbers which unknown to you are the nth digit of pi onwards, you may think you have entropy by "tests".
Mon May 18 21:29:17 UTC 2015 <justJanne> @ascii_field, about pi: No, pi is not a good source of entropy
Mon May 18 21:16:28 UTC 2015 <mircea_popescu> (if you think about it : an entropy source that always pass tests is by definition not entropic. see last year's amusement with the "guess number" toy alf made)
Mon May 18 02:50:55 UTC 2015 <decimation> lol she claims that (52:41) that openssl just adds the current time of day in seconds to the entropy pool
Sun May 17 19:09:36 UTC 2015 <mircea_popescu> and then, as that's ripped out, some tests will find the entropy not as good
Mon May 11 18:24:46 UTC 2015 <mats> (as long as you fill unused flash with high entropy NOPs that eventually jump to a fault handler, and do attestation via reset to a minimal bootloader that can use all memory)
Thu May 07 05:04:14 UTC 2015 <ben_vulpes> asciilifeform, mircea_popescu and others interested in entropic information: what stats about generated entropy are useful? if i need to shoop my entropy over to gentoo i can, but if that's not necessary (for dieharder tests) i'd like to avoid it
