UUID Generator

What is UUID?

UUID (Universally Unique Identifier) is a 128-bit identifier that is unique across both space and time, with minimal coordination between systems generating IDs. They are used in distributed systems, databases, and applications where unique identification is crucial.

How to Use This Tool

1. Set the quantity of UUIDs you want to generate (between 1 and 100).
2. Click the "Generate" button to create new UUIDs.
3. Click the "Clear" button to remove all generated UUIDs.
4. Use the copy button next to each UUID to copy it to your clipboard.
5. Use the "Copy All" button to copy all generated UUIDs at once (separated by new lines).

Common Use Cases

• Database Primary Keys: UUIDs are commonly used as primary keys in databases, especially in distributed systems.
• User/Session Identification: To identify users or sessions in web applications.
• Distributed Systems: For generating IDs without coordination between nodes.
• Content Addressing: As unique identifiers for files or content.
• Security Tokens: As unique tokens for various security purposes.

Version 4 UUID Format

This tool generates Version 4 UUIDs, which are randomly generated. The format is:xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx
where 'x' is any hexadecimal digit and 'y' is one of 8, 9, A, or B.

Technical Note

All UUIDs are generated client-side in your browser using the 'uuid' library. No data is sent to any server during this process.
