%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.
|
|
|
|
Only Perl CORE modules are used, making this very portable. However,
|
|
systems must have a high resolution timer and support 'usleep' 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. Note that this should be an
|
|
unusual case, and neither flag has any effect if the module considers
|
|
itself strong.
