 /* ----------------------------------------------------------------------------
 To initialize a fresh random context we rely on the OS:
-- Windows     : BCryptGenRandom
+- Windows     : RtlGenRandom
 - osX,bsd,wasi: arc4random_buf
 - Linux       : getrandom,/dev/urandom
 If we cannot get good randomness, we fall back to weak randomness based on a timer and ASLR.
