Subject: Use /dev/urandom for new client identity generation
X-Git-Tag: 3.3^2~4
X-Git-Url: http://www.git.cypherpunks.ru/?a=commitdiff_plain;h=cb530f030f975afad01155d559e1d16b16bd3097;p=govpn.git

Use /dev/urandom for new client identity generation

* FreeBSD has /dev/random and it never blocks, giving as much entropy as requested
* GNU/Linux has /dev/random can give shorter output
* /dev/urandom exists in both systems and never blocks
