%description
Generate random numbers using entropy gathered from timer / scheduler
jitter.

This can be used to generate non-pseudorandom data to seed a PRNG (e.g.
'srand'/'rand', Math::Random::MT, etc.) or CSPRNG (e.g. AES-CTR or
Math::Random::ISAAC). You may use it directly or as part of a random source
module that first checks for O/S randomness sources such as
Crypt::Random::Seed.

Only Perl CORE modules are used, making this very portable. However,
systems must have both 'usleep' and the high resolution timer interface
from Time::HiRes.

At installation time, measurements are taken of the estimated entropy
gathered by the timer differences. If the results indicated we could not
get good results, then the module will consider itself "weak". On the first
use of any of the functions that return randomness (e.g. random_bytes), the
module will carp about not being a strong randomness source. However, two
special options, ":strong" and ":weak" may be given to the importer to
change this behavior. If ":strong" is used, then the module will croak. If
":weak" is used, then no carp will be generated. The function 'is_strong'
can be used at any time for finer control. Most desktop UNIX/Windows
machines will give strong results from this method.
