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        my $fh;
13        my $iod = IO::Digest->new ($fh, 'MD5');
14
15        print $fh "fooo";
16        print $iod->hexdigest
17

DESCRIPTION

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