NAME

       Crypt::Random::Source - Get weak or strong random data from pluggable sources

VERSION

       version 0.14

SYNOPSIS

           use Crypt::Random::Source qw(get_strong);

           # get 10 cryptographically strong random bytes from an available source
           my $bytes = get_strong(10);

DESCRIPTION

       This module provides implementations for a number of byte oriented sources of random data.

       See Crypt::Random::Source::Factory for a more powerful way to locate sources, and the various sources for
       specific implementations.

EXPORTS

       get
       get_weak
       get_strong
           These functions delegate to a source chosen by an instance of Crypt::Random::Source::Factory, calling
           get

CAVEATS

       In versions prior to 0.13, "rand" could be used as a result of calling "get_weak", or "get", if no random
       device  was  available. This implies that not explicitly asking for "get_strong" on a non POSIX operating
       system (e.g.  Win32 without the Win32 backend) could have resulted in non cryptographically random data.

       Relatedly, the characterization  of  "urandom"  as  a  weak  source  of  randomness  is  also  largely  a
       misconception, see <https://www.2uo.de/myths-about-urandom/> for example.
