Works fine for me, even without the @EXPORT_OK change. You'll need to find out why the loop that starts with for $alg (1, 224, 256, 384, 512) doesn't get executed for you.

Start by making sure you are loading the module you think you are loading. You can do so using 

use Cwd qw( realpath );
print(realpath($INC{'Digest/SHA/PurePerl.pm'}), "\n");

If you are indeed executing the module you think you are executing, you've probably got a very serious problem with your Perl build.
