# UUID package for Go language [](https://travis-ci.org/satori/go.uuid) [](https://coveralls.io/github/satori/go.uuid) [](http://godoc.org/github.com/satori/go.uuid) This package provides pure Go implementation of Universally Unique Identifier (UUID). Supported both creation and parsing of UUIDs. With 100% test coverage and benchmarks out of box. Supported versions: * Version 1, based on timestamp and MAC address (RFC 4122) * Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1) * Version 3, based on MD5 hashing (RFC 4122) * Version 4, based on random numbers (RFC 4122) * Version 5, based on SHA-1 hashing (RFC 4122) ## Installation Use the `go` command: $ go get github.com/satori/go.uuid ## Requirements UUID package requires Go >= 1.2. ## Example ```go package main import ( "fmt" "github.com/satori/go.uuid" ) func main() { // Creating UUID Version 4 u1 := uuid.NewV4() fmt.Printf("UUIDv4: %s\n", u1) // Parsing UUID from string input u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8") if err != nil { fmt.Printf("Something gone wrong: %s", err) } fmt.Printf("Successfully parsed: %s", u2) } ``` ## Documentation [Documentation](http://godoc.org/github.com/satori/go.uuid) is hosted at GoDoc project. ## Links * [RFC 4122](http://tools.ietf.org/html/rfc4122) * [DCE 1.1: Authentication and Security Services](http://pubs.opengroup.org/onlinepubs/9696989899/chap5.htm#tagcjh_08_02_01_01) ## Copyright Copyright (C) 2013-2018 by Maxim Bublis <b@codemonkey.ru>.
