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.
