The UUID Generator by Small SEO Tools produces UUIDs (Universally Unique Identifiers) compliant with RFC 4122 standards. UUIDs are 128-bit numbers used to uniquely identify resources in software, databases, or distributed systems. This tool generates versions 1 (time-based), 3/5 (namespace-based), and 4 (random) UUIDs, ensuring global uniqueness and reliability.
How It Works
Select a UUID version (default is v4) and click "Generate." For example, a v4 UUID might look like f47ac10b-58cc-4372-a567-0e02b2c3d479. The tool also supports bulk generation for large-scale applications.
Key Features
Multiple Versions: Generate v1, v3/v5 (MD5/SHA-1), and v4 UUIDs.
Custom Namespaces: Input namespace UUIDs for v3/v5 generation.
Copy-Paste Formats: Choose hyphenated, uppercase, or lowercase outputs.
Use Cases
Database Keys: Assign unique IDs to records in NoSQL or SQL databases.
APIs: Generate transaction or session IDs for secure API calls.
IoT Devices: Identify devices in a network with collision-resistant UUIDs.
Benefits
Manual UUID creation risks duplicates. This tool guarantees uniqueness, critical for scalable systems.
FAQs
