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)

Use the go command:

$ go get github.com/satori/go.uuid

UUID package requires any stable version of Go Programming Language.

It is tested against following versions of Go: 1.0-1.5

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 is hosted at GoDoc project.
