# UUID package for Go language
[![Build Status](https://travis-ci.org/satori/go.uuid.png?branch=master)](https://travis-ci.org/satori/go.uuid)
[![Coverage Status](https://coveralls.io/repos/github/satori/go.uuid/badge.svg?branch=master)](https://coveralls.io/github/satori/go.uuid)
[![GoDoc](http://godoc.org/github.com/satori/go.uuid?status.png)](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.
