Ossp uuid is an iso-c and perl application programming interface (api) and corresponding command line interface (cli) for the generation of dce 1.1 and iso/iec 11578:1996 compliant universally unique identifier (uuid). it supports dce 1.1 variant uuids of version 1 (time and node based), version 3 (name based) and version 4 (random number based).

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.

this package provides a module for ossp uuid functions support in php scripts.
