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.
|
|
|
|
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.
