win32: use RtlGenRandom for /dev/urandom

2025-10-09T06:49:58+00:00

Use the (somewhat ancient) Microsoft RtlGenRandom() function to provide random data for /dev/urandom. Saves 176-240 bytes. (GitHub issue #519)

win32: allow use of shell's PRNG for /dev/urandom

2018-03-22T15:11:41+00:00

Allow either ISAAC or the shell's built-in pseudo-random number generator to be used for /dev/urandom. The latter is smaller so it's the default.
