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.
