Abstract
OSSP uuid is a ISO-C:1999 application programming interface (API) and
corresponding command line interface (CLI) for the generation of DCE
1.1, ISO/IEC 11578:1996 and RFC 4122 compliant Universally Unique
Identifier (UUID). It supports DCE 1.1 variant UUIDs of version 1 (time
and node based), version 3 (name based, MD5), version 4 (random number
based) and version 5 (name based, SHA-1). Additional API bindings are
provided for the languages ISO-C++:1998, Perl:5 and PHP:4/5. Optional
backward compatibility exists for the ISO-C DCE-1.1 and Perl Data::UUID
APIs.
UUIDs are 128 bit numbers which are intended to have a high likelihood
of uniqueness over space and time and are computationally difficult
to guess. They are globally unique identifiers which can be locally
generated without contacting a global registration authority. UUIDs
are intended as unique identifiers for both mass tagging objects
with an extremely short lifetime and to reliably identifying very
persistent objects across a network.
