It supports DCE 1.1 variant UUIDs of version 16 1 (time and node based), version 3 (name based, MD5), version 4 17 (random number based) and version 5 (name based, SHA-1). Additional 18 API bindings are provided for the languages ISO-C++:1998, Perl:5 and 19 PHP:4/5. Optional backward compatibility exists for the ISO-C DCE-1.1 20 and Perl Data::UUID APIs. 21 22 UUIDs are 128 bit numbers which are intended to have a high likelihood 23 of uniqueness over space and time and are computationally difficult 24 to guess. They are globally unique identifiers which can be locally 25 generated without contacting a global registration authority. UUIDs 26 are intended as unique identifiers for both mass tagging objects 27 with an extremely short lifetime and to reliably identifying very 28 persistent objects across a network. 29 30 COPYRIGHT AND LICENSE 31 32 Copyright (c) 2004-2008 Ralf S.
