Line 5:
: OpenBSD 4.8 and before had /dev/urandom giving random numbers, but /dev/random giving only errors. (This was because /dev/random was a reserved device, and /dev/srandom of OpenBSD was like /dev/random of Linux.) So /dev/urandom was better than /dev/random for OpenBSD. This has changed with OpenBSD 4.9 (from May 2011); now /dev/random also gives random numbers. So if some example on Rosetta Code uses /dev/random, I will not care to change it to /dev/urandom. --[[User:Kernigh|Kernigh]] 04:47, 8 May 2011 (UTC)
feels like this is all outdated now. please, read my comment below! 😘 --[[User:Cregox|cregox]] ([[User talk:Cregox|talk]]) 11:13, 5 January 2021 (UTC)

::: Er. I was unclear. Clarification handy, though: [http://irclog.perlgeek.de/rosettacode/2011-01-11#i_3175701 http://irclog.perlgeek.de/rosettacode/2011-01-11#i_3175701] --[[User:Short Circuit|Michael Mol]] 15:21, 11 January 2011 (UTC)
:::: OK: So let's say, it should involve real-world generated entropy during each step, and define the scope of this task to what is covered by the Wikipedia article. --[[User:Abu|Abu]] 15:26, 11 January 2011 (UTC)
==/dev/urandom==
in #pearl someone said:
: Whether /dev/urandom is good enough for cryptographic work is debated, though on most UNIX systems it is at least as good as the Win32 Crypto API.
that's also what came up on the summary i found on duck when searching for `kotlin dev/urandom`.
but is it really debated? or is this outdated? or was it ever true?
from what i've been researching on my free time since yesterday, both `/dev/random` and u are not only good enough, they're actively used for cryptographic work. and given windows is now linux, i highly doubt it would use any other resource for true randomness (plus windows have always been notoriously less secure than any *nix to begin with).
feels like a "global warming" debate, if john oliver knows what i mean.
