Versions 3 and 5 are well suited for use as unique identifiers for information and data within a namespace of a system.ДЄn extra version of UUID, and a special case, is the Nil UUID. However, it is generated using Secure Hash Algorithm 1, or SHA-1, as opposed to MD5, which version 3 uses for hashing. Version 5 is generated the same way as version 3. However, there are still enough UUID combinations to avoid the possibility of a collision. More bits are used in this version, so there are fewer UUID combinations. These can be created using a random or pseudo-random number generator. Although the random UUID uses random bytes, four bits are used to indicate version 4, while two to three bits are used to indicate the variant. This version of UUID is generated randomly. Versions 3 and 5 are constructed similarly however, version 3 uses message-digest algorithm 5 ( MD5) as the hashing algorithm. This version is generated by hashing both a namespace identifier and a name. These are reserved for DCE Security UUIDs. Namely, eight bits of the clock sequence are replaced by a local domain number and 32 bits of the timestamp are replaced with the number for the specified local domain. This version is generated similarly to version 1, however, less significant bits are replaced. This version is generated from a specified time and node It is a time stamp-based unique host identifier. These versions differ in how they are constructed. The current variant of UUID, variant 1, consists of five different versions.

Variant 1 UUIDs use two bits, while variant 2 UUIDs use three bits. The difference between variants 1 and 2 is the number of bits in the N position. Even though many of the GUIDs Microsoft uses are variant 1 UUIDs, early GUIDs on the Windows platform used variant 2. Variant 2 is reserved for Microsoft backward compatibility. As an example, GUIDs are variant 1 UUIDs. These variants are referred to as RFC 4122/DCE 1.1 UUIDs, or Leach-Salz UUIDs after the authors of the Internet Engineering Task Force working document defining UUID specifications. Variant 1 is the main variant used today.

It has a similar construction to the version 1 UUIDs used today. This variant is reserved for backward compatibility with the obsolete Apollo Network Computing System from the late 1980s.

Free tools to generate UUIDs include UUIDTools or Online UUID Generator. UUIDs are generated using an algorithm based on a timestamp and other factors such as the network address. Different versions of UUID follow the RFC 4122 specification.

UUID was standardized by the Open Software Foundation (OSF), becoming a part of the Distributed Computing Environment ( DCE). Originally, GUID referred to a variant of UUID used by Microsoft, but the terms became synonymous in the RFC 4122 specification.

UUIDs can be generated to refer to almost anything imaginable.В For example, they can identify databases, system instances, primary keys, Bluetooth profiles or objects with short lifetimes. Depending on the specific mechanisms used, a UUID is either guaranteed to be different or is, at least, extremely likely to be different from any other UUID generated until A.D. Gillis, Technical Writer and EditorДЄ UUID (Universal Unique Identifier) is a 128-bit value used to uniquely identify an object or entity on the internet.
