laravel-uuid - Laravel package to generate and to validate a UUID according to the RFC 4122 standard

•    PHP

---

Laravel package to generate and to validate a universally unique identifier (UUID) according to the RFC 4122 standard. Support for version 1, 3, 4 and 5 UUIDs are built-in. Laravel-uuid is now refactored for Laravel 5.5. It has the same requirements so that means PHP 7. Laravel package auto-discovery is enabled, and you can now use the UUID validation. Validation examples are below and in the tests.

FCUUID - iOS UUID / Universally Unique Identifiers library as alternative to UDID and identifierForVendor

•    Objective-C

---

iOS UUID library as alternative to the old good UDID and identifierForVendor. This library provides the simplest API to obtain universally unique identifiers with different levels of persistence. It's possible to retrieve the UUIDs created for all devices of the same user, in this way with a little bit of server-side help it's possible manage guest accounts across multiple devices easily.

uuid - A UUID package originally forked from github.com/satori/go.uuid

•    Go

---

Package uuid provides a pure Go implementation of Universally Unique Identifiers (UUID) variant as defined in RFC-4122. This package supports both the creation and parsing of UUIDs in different formats. This project was originally forked from the github.com/satori/go.uuid repository after it appeared to be no longer maintained, while exhibiting critical flaws. We have decided to take over this project to ensure it receives regular maintenance for the benefit of the larger Go community.

laravel-binary-uuid - Optimised binary UUIDs in Laravel

•    PHP

---

Using a regular uuid as a primary key is guaranteed to be slow. This package solves the performance problem by storing slightly tweaked binary versions of the uuid. You can read more about the storing mechanism here: http://mysqlserverteam.com/storing-uuid-values-in-mysql-tables/.

ksuid - K-Sortable Globally Unique IDs

•    Go

---

ksuid is a Go library that can generate and parse KSUIDs. KSUID is for K-Sortable Unique IDentifier. It's a way to generate globally unique IDs similar to RFC 4122 UUIDs, but contain a time component so they can be "roughly" sorted by time of creation. The remainder of the KSUID is randomly generated bytes.

uuid - Automatically exported from code.google.com/p/go-uuid

•    Go

---

The uuid package generates and inspects UUIDs based on RFC 4122 and DCE 1.1: Authentication and Security Services. This package now leverages the github.com/google/uuid package (which is based off an earlier version of this package).

uuid - Generates universally unique identifiers (UUIDs) for use in distributed applications.

•    Ruby

---

Generates universally unique identifiers (UUIDs) for use in distributed applications. Based on RFC 4122.Call #generate to generate a new UUID. The method returns a string in one of three formats. The default format is 36 characters long, and contains the 32 hexadecimal octets and hyphens separating the various value parts. The :compact format omits the hyphens, while the :urn format adds the :urn:uuid prefix.

shortuuid - :mushroom: A generator library for concise, unambiguous and URL-safe UUIDs

•    Go

---

A Go library that generates concise, unambiguous, URL-safe UUIDs. Based on and compatible with the Python library shortuuid. Often, one needs to use non-sequential IDs in places where users will see them, but the IDs must be as concise and easy to use as possible. shortuuid solves this problem by generating UUIDs using google/uuid and then translating them to base57 using lowercase and uppercase letters and digits, and removing similar-looking characters such as l, 1, I, O and 0.

humanhash - Human-readable digests.

•    Python

---

humanhash provides human-readable representations of digests. Don't store the humanhash output, as its statistical uniqueness is only around 1 in 4.3 billion. Its intended use is as a human-readable (and, most importantly, memorable) representation of a longer digest, unique enough for display in a user interface, where a user may need to remember or verbally communicate the identity of a hash, without having to remember a 40-character hexadecimal sequence. Nevertheless, you should keep original digests around, then pass them through humanize() only as you're displaying them.
