Digest::SHA1 - Perl interface to the SHA-1 Algorithm |
NAME
Digest::SHA1 - Perl interface to the SHA-1 Algorithm
SUPPORTED PLATFORMS
- Linux
- Solaris
- Windows
SYNOPSIS
# Functional style use Digest::SHA1 qw(sha1 sha1_hex sha1_base64);
$digest = sha1($data); $digest = sha1_hex($data); $digest = sha1_base64($data);
# OO style use Digest::SHA1;
$ctx = Digest::SHA1->new;
$ctx->add($data); $ctx->addfile(*FILE);
$digest = $ctx->digest; $digest = $ctx->hexdigest; $digest = $ctx->b64digest;
DESCRIPTION
The Digest::SHA1 module allows you to use the NIST SHA-1 message
digest algorithm from within Perl programs. The algorithm takes as
input a message of arbitrary length and produces as output a 160-bit
``fingerprint'' or ``message digest'' of the input.
The Digest::SHA1 module provide a procedural interface for simple
use, as well as an object oriented interface that can handle messages
of arbitrary length and which can read files directly.
A binary digest will be 20 bytes long. A hex digest will be 40 characters long. A base64 digest will be 27 characters long.
FUNCTIONS
The following functions can be exported from the Digest::SHA1
module. No functions are exported by default.
sha1($data,...)
- This function will concatenate all arguments, calculate the SHA-1 digest of this ``message'', and return it in binary form.
sha1_hex($data,...)
- Same as sha1(), but will return the digest in hexadecimal form.
sha1_base64($data,...)
- Same as sha1(), but will return the digest as a base64 encoded string.
METHODS
The Digest::SHA1 module provide the standard Digest OO-interface.
The constructor looks like this:
- $sha1 = Digest->
new('SHA-1')
- $sha1 = Digest::SHA1->new
-
The constructor returns a new
Digest::SHA1object which encapsulate the state of the SHA-1 message-digest algorithm. You can add data to the object and finally ask for the digest using the methods described in the Digest manpage.
