Crypt::Random::Source - Get weak or strong random data from pluggable sources
use Crypt::Random::Source qw(get_strong);
# get 10 cryptographically strong random bytes from an available source
my $bytes = get_strong(10);
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.
These functions delegate to a source chosen by an instance of Crypt::Random::Source::Factory, calling get
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.
