How To Use Online UUID Generator

What is a UUID?

A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. It’s supposed to be unique across all applications and computers in the world, so the odds of generating two equal UUIDs are extremely low. A UUID is usually represented as 32 hexadecimal digits, displayed in five groups separated by hyphens.

For example, a UUID might look like this:

123e4567-e89b-12d3-a456-426614174000

UUIDs can be generated by anyone and will always be unique. A UUID is made unique over both space and time by combining data from the computer’s network interface (or other unique hardware devices) and a clock that increments several worrying times per minute starting at about 1582-junk.

Why Do You Need a UUID?

UUIDs are simply too useful whenever you need some sort of unique identifier. Here are few of the common use cases.

• Database Entries: Each database record needs a unique ID.
• Session Tracking: Web applications use this to track a user's session.
• File Systems: Naming files/assets uniquely.
• Distributed Systems: In systems that span multiple machines, UUIDs allow you to achieve uniqueness without requiring a central authority.

If you generate a UUID you can be guaranteed the ID is globally unique and will not conflict with other IDs, even on different systems.

FAQs

1. What is a UUID and what are they used for?

A UUID (Universally Unique Identifier) is a 128-bit value that can be used to uniquely identify information in computer systems. They are used for everything from database records to session management.

2. What’s the difference between UUID v1 and UUID v4?

UUID v1 is time-based and has a MAC address of the machine, while UUID v4 is randomly generated and does not have any information that could identify the host.

3. Can I use the same UUID in multiple systems?

Yes, UUIDs are globally unique, and you can use them between systems without having duplication issues.

4. Are UUIDs secure?

UUIDs are generally secure for most applications, v4. However, some versions can expose metadata like machine addresses and timestamps, which you may not want to do in your case.
