Crypt::Random::Source3pm

Usage

    use Crypt::Random::Source qw(get_strong);
    # get 10 cryptographically strong random bytes from an available source
    my $bytes = get_strong(10);

Version

version 0.14

Overview

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.
