200 2016-05-03T13:06:26  <Chris_Stewart_5> Currently getting a script parse error
201 2016-05-03T13:10:43  <instagibbs> Chris_Stewart_5, link to code? Worst case it's an noop
202 2016-05-03T13:12:23  <Chris_Stewart_5> instagibbs: Actually is OP_CSV not merged into master yet? https://github.com/bitcoin/bitcoin/blob/a6a860796a44a2805a58391a009ba22752f64e32/src/script/script.cpp#L134
203 2016-05-03T13:15:03  <instagibbs> it's still named NOP3 in most parts afaik
204 2016-05-03T13:15:04  <instagibbs> https://github.com/bitcoin/bitcoin/blob/a6a860796a44a2805a58391a009ba22752f64e32/src/test/data/tx_valid.json#L239
205 2016-05-03T13:15:21  <instagibbs> once activated I think more renaming will occur

406 2016-05-03T21:24:52  <gmaxwell> The openssl output has a header, so it will not be totally random.
407 2016-05-03T21:25:12  <sipa> i'd just write /dev/urandom
408 2016-05-03T21:25:18  <sipa> if you're paranoid
409 2016-05-03T21:25:23  <sipa> overwrite it 2 times
410 2016-05-03T21:26:02  <wallet42> i use /dev/urandom as initializer but my SSD can write 900 MB/s, why settle for 12 MB/s
411 2016-05-03T21:26:27  <wallet42> is there a crypto reason this is a bad PRNG?
412 2016-05-03T21:26:30  <gmaxwell> wallet42: note that on modern disks (esp for SSD), there really is no safe way to overwrite the whole disk.
413 2016-05-03T21:27:06  <sipa> i think there is typical advice not to use aes-ctr for very large messages without rekeying
414 2016-05-03T21:27:17  <gmaxwell> there is a 'secure erase' available from hdparm which is specified to erase more than you can normally access, but it's anyone's guess at how effective it actually is.
415 2016-05-03T21:27:50  <gmaxwell> sipa: I think any single disk that exists is small enough where that issue doesn't matter.
416 2016-05-03T21:28:03  <sipa> aes-ctr is by definition a bad prng, as it produces a permutation, not a random function
417 2016-05-03T21:28:17  <sipa> also, the argument is unlikely to matter here
418 2016-05-03T21:28:37  <gmaxwell> But if your goal is to not have it clear you overwrote it with openssl that command won't work due to the header.
419 2016-05-03T21:28:49  <sipa> you don't need a perfectly random function, just something unoredictable is enough
420 2016-05-03T21:28:49  <gmaxwell> doing that then overwriting with zeros would.
421 2016-05-03T21:28:59  <wallet42> would a sha256(password+nonce) be better than aes-ctr?
422 2016-05-03T21:29:18  <gmaxwell> it would be much slower.
423 2016-05-03T21:29:27  <sipa> it would be a random function, though
424 2016-05-03T21:29:43  <sipa> or at least, indistinguishable from one
425 2016-05-03T21:30:14  <wallet42> ok so sha256's randomness is better than aes-ctr
426 2016-05-03T21:30:21  <sipa> in theory

428 2016-05-03T21:31:05  <sipa> i don't think the distuishability matters here at all
429 2016-05-03T21:33:40  <wallet42> how can i bench libsecp256k1
430 2016-05-03T21:34:31  <sipa> it has a bench binary
431 2016-05-03T21:35:01  <wallet42> ah --enable-benchmark
432 2016-05-03T21:35:04  <wallet42> sorry
433 2016-05-03T21:35:26  <sipa> oh right, it's not standard anymore
