%description
frandom is a kernel module. It's the machinery between a special
device driver, /dev/frandom, which behaves very much like
/dev/urandom, only it creates data faster. Much faster. And it doesn't
use much or any kernel entropy.

%description -l pl.UTF-8
frandom to moduł jądra stojący za urządzeniem specjalnym /dev/frandom,
które zachowuje się bardzo podobnie do /dev/urandom, ale tworzy dane
szybciej, dużo szybciej. I nie zużywa zbyt dużo (lub wcale) entropii
jądra.
