Universally Unique Identifier Command-Line Tool

OSSP uuid is a C API and corresponding CLI program for the generation and analysis of DCE 1.1 and, IETF RFC-9562- compliant Universally Unique Identifiers (UUIDs). It supports variant 1 UUIDs of versions:

  1 (time and node),
  3 (name (namespace data), MD5),
  4 (random),
  5 (name (namespace data), SHA-1),
  6 (time and node with improved locality),
  7 (UNIX time, random data).

Additional API bindings are provided for C 98 (deprecated) and Perl: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.

This package contains the Universally Unique Identifier Command-Line Tool.
