A simple universally unique ID generation library.

UUID generator for producing universally unique identifiers based on RFC 4122 (http://www.ietf.org/rfc/rfc4122.txt).

Guid is a Ruby library for portable GUID/UUID generation. At the moment it can be used on Windows (except first release of Win95 and older) and on Unix. This is a fork of David Garamond's ruby-uuid library.

This gem is a Logstash plugin required to be installed on top of the Logstash core pipeline using $LS_HOME/bin/logstash-plugin install gemname. This gem is not a stand-alone program

Simple, scalable UUID generation.

Let ActiveRecord serialize and cast your UUIDs to and from binary columns in your database.

Add binary (not string) UUIDs to ActiveRecord in MySQL

Useful helpers to consistently migrate Integer id columns to UUID in PostgreSql. Special support for primary keys and references.

Temporally Ordered IDs. Generate universally unique identifiers (UUID) that sort lexically in time order. Torid exists to solve the problem of generating UUIDs that when ordered lexically, they are also ordered temporally. I needed a way to generate ids for events that are entering a system with the following criteria: 1. Fast ID generation 2. No central coordinating server/system 3. No local storage 4. Library code, that is multiple apps on the same machine can use the same code and they will not generate duplicate ids 5. Eventually stored in a UUID field in a database. So 128bit ids are totally fine. The IDs that Torid generates are 128bit IDs made up of 2, 64bit parts. * 64bit microsecond level UNIX timestamp * 64bit hash of the system hostname, process id and a random value.

Druuid generates 64-bit, time-sortable UUIDs.

Quickly and easily convert UUIDs to space efficient Base62 strings.

Override migration methods to support UUID columns without having to be explicit about it.

Generate UUID(rfc4122) version 3(based on md5) or version 5(based on sha-1).
