Math::Prime::Util::Entropy - Get a good random seed
Version 0.73
Provides a single method to get a good seed if possible. This is a streamlined version of Crypt::Random::Seed, with ideas from Bytes::Random::Secure::Tiny.
Takes a number of bytes "n" and returns either undef (no good seed available) or a binary string with good entropy.
We try in order:
- the Win32 Crypto API - /dev/urandom - /dev/random - L<Crypt::Random::Seed> - L<Crypt::PRNG>
