NAME

Math::Prime::Util::Entropy - Get a good random seed

VERSION

Version 0.68

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>
