NAME

6       IO::Digest - Calculate digests while reading or writing
7

SYNOPSIS

9        use IO::Digest;
10
11        # Get a Digest::MD5 object that takes input while $fh being written or read
12        $iod = IO::Digest->new ($fh, 'MD5');
13
14        print $fh "fooo";
15        print $iod->hexdigest
16

DESCRIPTION

18       This module allows you to calculate digests while reading or writing
19       file handles.  This avoids the case you need to reread the same content
20       to compute the digests after written a file.
