NAME

6       Crypt::Random::Source - Get weak or strong random data from pluggable
7       sources
8

VERSION

10       version 0.14
11

SYNOPSIS

13           use Crypt::Random::Source qw(get_strong);
14
15           # get 10 cryptographically strong random bytes from an available source
16           my $bytes = get_strong(10);
17

DESCRIPTION

19       This module provides implementations for a number of byte oriented
20       sources of random data.
21
22       See Crypt::Random::Source::Factory for a more powerful way to locate
23       sources, and the various sources for specific implementations.
24

EXPORTS

26       get
27       get_weak
28       get_strong
29           These functions delegate to a source chosen by an instance of
30           Crypt::Random::Source::Factory, calling get
31

CAVEATS

33       In versions prior to 0.13, "rand" could be used as a result of calling
34       "get_weak", or "get", if no random device was available. This implies
35       that not explicitly asking for "get_strong" on a non POSIX operating
36       system (e.g.  Win32 without the Win32 backend) could have resulted in
37       non cryptographically random data.
38
39       Relatedly, the characterization of "urandom" as a weak source of
40       randomness is also largely a misconception, see
41       <https://www.2uo.de/myths-about-urandom/> for example.
