In all methods, is a UUID and is a free form string. This modules provides several methods to create a UUID.

This module provides the creation of version 1 time based UUIDs (using random multicast MAC addresses), version 3 MD5 based UUIDs, version 4 random UUIDs, and version 5 SHA-1 based UUIDs. (See RFC 4122.) It provides reasonably efficient and reliable framework for generating UUIDs and supports fairly high allocation rates - 10 million per second per machine - and therefore is suitable for identifying both extremely short-lived and very persistent objects on a given system as well as across the network. UUID::Tiny is a lightweight, low dependency Pure Perl module for UUID creation and testing. The algorithm for UUID generation, used by this extension, is described in the Internet Draft 'UUIDs and GUIDs' by Paul J. Microsoft COM/DCOM for instance, uses GUIDs very extensively to uniquely identify classes, applications and components across network-connected systems.

#Perl uuid generator software#

Currently many different technologies rely on UUIDs to provide unique identity for various software components. UUIDs were originally used in the Network Computing System (NCS) and later in the Open Software Foundation's (OSF) Distributed Computing Environment. A UUID is 128 bits long, and is guaranteed to be different from all other UUIDs/GUIDs generated until 3400 CE. This module provides a framework for generating v3 UUIDs (Universally Unique Identifiers, also known as GUIDs (Globally Unique Identifiers). $uuid = $ug->from_string( $str ) DESCRIPTION Its interface may be just a little more straightforward for the average Perl programer. Right now, it relies on Data::UUID, but it may not in the future.

The module Data::GUID provides another interface for generating GUIDs. Data::UUID - Globally/Universally Unique Identifiers (GUIDs/UUIDs) SEE INSTEAD?
