Random UUID (v4) Generator

What is a UUID?

A Universally Unique Identifier (UUID) is a 128-bit number that is used to identify information in computer systems. UUIDs are used to uniquely identify objects, and are commonly used in a variety of applications, including databases, software applications, and web services.

What is a v4 UUID?

Version-4 UUIDs are a type of UUID that are randomly generated on-the-fly, rather than being generated based on a machine's hardware or time-based identifier. As such, they are tightly random, and resistant to bias or correlation.

Using the Random UUID v4 Generator

The Random UUID v4 Generator is a simple tool for generating version-4 UUIDs. To use the generator:

1. Click the "Generate UUID" button to generate a random UUID.
2. You can then copy and paste the generated UUID into your application or database.

How the Generator Works

The Random UUID v4 Generator uses a cryptographically secure pseudo-random number generator to generate the UUID. This means that the generated UUIDs are highly unlikely to be predictable or correlated, and are suitable for a wide range of applications.

Security Considerations

When using the Random UUID v4 Generator, please be aware of the following security considerations:

• The generated UUIDs are not guaranteed to be uncorrelated, and may be predictable if an attacker has access to the underlying random number generator.
• The generated UUIDs may be used as input to other algorithms or systems, which may introduce additional security concerns.

Limitations

The Random UUID v4 Generator is subject to the following limitations:

• The generated UUIDs may be truncated or wrapped if they exceed the maximum value that can be stored or transmitted.
• The generated UUIDs may be affected by the underlying random number generator, which may have biases or flaws.

API and Reference

The Random UUID v4 Generator is available as a lightweight API for integrating into your own applications. The API documentation can be found here.
