Crypt::Random::Source::Base - Abstract base class for Crypt::Random::Source classes
use Moo; extends qw(Crypt::Random::Source::Base);
This is an abstract base class. In the future it will be a role.
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
