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.
