Looks like I should try regular SHA

This module has numerious known bugs, is not compatable with the Digest interface and its functionality is a subset of the functionality of Digest::SHA (which is in perl core as of 5.9.3).
Please use Digest::SHA instead of this module in new and old code.
It looks like SAH even supports Base-64 which will keep the associative array table to the minimum size (what I suspect was breaking my initial AWK routine).

NAME
IO::Digest - Calculate digests while reading or writing SYNOPSIS
use IO::Digest; # Get a Digest::MD5 object that takes input while $fh being written or read my $fh; my $iod = IO::Digest->new ($fh, 'MD5'); print $fh "fooo"; print $iod->hexdigest DESCRIPTION
This module allows you to calculate digests while reading or writing file handles. This avoids the case you need to reread the same content to compute the digests after written a file. TEST COVERAGE
