NAME

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

VERSION

Version 0.73

SYNOPSIS

DESCRIPTION

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.

entropy_bytes

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>
