Need to generate a file with random data. /dev/[u]random doesn't exist.

Need to use dd to generate a large file from a sample file of random data. This is because I don't have /dev/urandom. I create a named pipe then: dd if=mynamed.fifo do=myfile.fifo bs=1024 count=1024 but when I cat a file to the fifo that's 1024 random bytes: cat randomfile.txt >...

NAME

       Crypt::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
