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.
