Digest::SHA1 is a Perl interface to the SHA-1 algorithm.

SYNOPSIS

# Functional style
use Digest::SHA1 qw(sha1 sha1_hex sha1_base64);

$digest = sha1($data);
$digest = sha1_hex($data);
$digest = sha1_base64($data);
$digest = sha1_transform($data);


# OO style
use Digest::SHA1;

$sha1 = Digest::SHA1->new;

$sha1->add($data);
$sha1->addfile(*FILE);

$sha1_copy = $sha1->clone;

$digest = $sha1->digest;
$digest = $sha1->hexdigest;
$digest = $sha1->b64digest;
$digest = $sha1->transform;

The Digest::SHA1 module allows you to use the NIST SHA-1 message digest algorithm from within Perl programs. The algorithm takes as input a message of arbitrary length and produces as output a 160-bit "fingerprint" or "message digest" of the input.

The Digest::SHA1 module provide a procedural interface for simple use, as well as an object oriented interface that can handle messages of arbitrary length and which can read files directly.
