NAME¶

Crypt::Random::Source::Base - Abstract base class for Crypt::Random::Source classes

VERSION¶

version 0.08

SYNOPSIS¶

    use Moose;
    extends qw(Crypt::Random::Source::Base);

DESCRIPTION¶

This is an abstract base class. In the future it will be a role.

METHODS¶

get $n, %args¶

Gets $n random bytes and returns them as a string. This method may produce fatal errors if the source was unable to provide enough data.

read $buf, $n, [ $off ]¶

This method is cannibalized from IO::Scalar. It provides an IO::Handle work-alike. Note that subclasses override this to operate on a real handle directly if available.

seed @stuff¶

On supporting sources this method will add @stuff, whatever it may be, to the random seed. Some sources may not support this, so be careful.

available¶

This is a class method, such that when it returns true calling "new" without arguments on the class should provide a working source of random data. This is use by Crypt::Random::Source::Factory.

rank¶

This is a class method, with some futz value for a ranking, to help known good sources be tried before known bad (slower, less available) sources.

get_data %Params¶

Provided for compatibility with Crypt::Random
