NAME

6       Crypt::Random::Source::Base - Abstract base class for
7       Crypt::Random::Source classes
8

VERSION

10       version 0.14
11

SYNOPSIS

13           use Moo;
14           extends qw(Crypt::Random::Source::Base);
15

DESCRIPTION

17       This is an abstract base class.
18
19       In the future it will be a role.
20

METHODS

22   get $n, %args
23       Gets $n random bytes and returns them as a string.
24
25       This method may produce fatal errors if the source was unable to
26       provide enough data.
27
28   read $buf, $n, [ $off ]
29       This method is cannibalized from IO::Scalar. It provides an IO::Handle
30       work-alike.
31
32       Note that subclasses override this to operate on a real handle directly
33       if available.
34
35   seed @stuff
36       On supporting sources this method will add @stuff, whatever it may be,
37       to the random seed.
38
39       Some sources may not support this, so be careful.
40
41   available
42       This is a class method, such that when it returns true calling "new"
43       without arguments on the class should provide a working source of
44       random data.
45
46       This is use by Crypt::Random::Source::Factory.
47
48   rank
49       This is a class method, with some futz value for a ranking, to help
50       known good sources be tried before known bad (slower, less available)
51       sources.
52
53   get_data %Params
54       Provided for compatibility with Crypt::Random
55
