Tue Oct 28 08:53:57 UTC 2014 <Naphex> so if you're running openssl it shouldn't go down below 200 bytes of available entropy
Tue Oct 28 08:53:32 UTC 2014 <CheckDavid> 200 bytes of entropy?
Tue Oct 28 08:52:40 UTC 2014 <CheckDavid> There's not enough entropy in the regular sensors of a computer?
Tue Oct 28 08:48:45 UTC 2014 <adlai> "dumb"? doesn't this just mean you can treat it as providing less entropy than the number of bits it spits out?
Tue Oct 28 02:36:56 UTC 2014 <mircea_popescu> cazalla: question if anyone can help - is there a genuine security reason for someone to refuse to disclose how they generate entropy for the private keys contained in their physical bitcoin coin products? << not really, no. other than "we don't have a clue how it's done but this is sekoority and so being mysterious is the next best thing"
Tue Oct 28 00:29:58 UTC 2014 <asciilifeform> cazalla: is there a genuine security reason for someone to refuse to disclose how they generate entropy << your crystal ball's answer is correct.
Tue Oct 28 00:26:03 UTC 2014 <PeterL> cazella: maybe they are not making good entropy and are embarrased to admit it?

Wed Oct 22 18:33:12 UTC 2014 <mircea_popescu> there HAVE been cases where bitcoin used shitty entropy.

Wed Oct 15 03:44:51 UTC 2014 <PinkPosixPXE> asciilifeform: For serious security, perhaps yes, but everything runs on hardware, it's just the software layer that interacts with how entropy is derived from teh hardware wether it's something you plug in or something you run on a server
Wed Oct 15 03:43:45 UTC 2014 <PinkPosixPXE> When the Mycelium Entropy is inserted into the USB drive, hardware-based entropy is harnessed to create a large, truly random, number. The random number is generated using a static RAM chip, which Holcomb, D.E.; Burleson, W.P.; and Fu. K. have proven is capable of generating “128-bit true random numbers.” This number is then used as the seed to generate a private key and corresponding Bitcoin
Wed Oct 15 03:43:17 UTC 2014 <PinkPosixPXE> There's that new usb device called 'entropy' which is a usb coin wallet, that you can just plug in https://www.cryptocoinsnews.com/mycelium-successfully-funds-usb-bitcoin-wallet-device-entropy-with-indiegogo/

Wed Oct 15 03:38:44 UTC 2014 <PinkPosixPXE> it uses /dev/urandom, it's not hardware driven, it just pulls entropy through rng-tools software, rather than 'mouse input' or 'disk activity' etc.
Wed Oct 15 03:36:07 UTC 2014 <PinkPosixPXE> Fixed my issue earlier today, entropy isn't solely hardware dependant,
Wed Oct 15 03:34:41 UTC 2014 <PinkPosixPXE> So we have to increase entropy somehow. This can be done with rng-tools, a package to use a hardware true number generator (TRNG). Don't worry, you don't need any extra hardware, we will use /dev/urandom as our true number generator.
