IO::Digest - Calculate digests while reading or writing
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
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.
