Crypt::Random::Source:UsereContributed Perl DocuCrypt::Random::Source::Base(3)NAMECrypt::Random::Source::Base - Abstract base class for
Crypt::Random::Source classes
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
