"Во FreeBSD устранена уязвимость в генераторе случайных чисел" Отправлено Осторожный, 25-Ноя-08 13:08
Действительно - тебе не мешает самому сначала прочитать arc4random(9) is a generic-purpose random number generator based on the key stream generator of the RC4 cipher.  It is expected to be cryptographically strong, and used throughout the FreeBSD kernel for a variety of purposes, some of which rely on its cryptographic strength. arc4random(9) is periodically reseeded with entropy from the FreeBSD kernel's Yarrow random number generator, which gathers entropy from a variety of sources including hardware interrupts.  During the boot process, additional entropy is provided to the Yarrow random number generator from userland, helping to ensure that adequate entropy is present for cryptographic purposes.
