IO::Digest(3)                        User Contributed Perl Documentation                       IO::Digest(3)



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
        $iod = IO::Digest->new ($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.
