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

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

This is an abstract base class.

In the future it will be a role.

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.

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.

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.

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.

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.

Provided for compatibility with Crypt::Random
