💡Sobre UUID v5
- ✓ Genera UUIDs deterministas (mismo nombre = mismo UUID)
- ✓ Usa SHA-1 para hashing del nombre y namespace
- ✓ Ideal para identificar recursos consistentemente
- ✓ Los namespaces predefinidos: DNS, URL, OID, X500
- ✓ Útil para generar IDs basados en dominios o URLs
The UUID v5 Generator creates deterministic namespace-based UUIDs using SHA-1 hashing and a namespace identifier. Generate consistent unique identifiers for databases, APIs, and distributed systems where you need reproducible UUID generation from input data. This free tool produces RFC 4122 compliant UUID v5 values that always generate the same UUID for identical namespace and name combinations. Perfect for developers building systems requiring deterministic IDs, creating consistent URLs, managing database relationships, or ensuring compatibility across services.

Preguntas Frecuentes
What is UUID v5?
UUID v5 is a namespace-based UUID generated using SHA-1 hashing. Same input always produces same UUID, making it deterministic unlike v4 (random) UUIDs.
When should I use v5 instead of v4?
Use v5 when you need reproducible IDs from input data. Use v4 for completely random identifiers. v5 is better for data consistency and debugging.
What namespaces are available?
Standard namespaces include DNS, URL, ISO OID, and X.500 distinguished names. You can also use custom namespace UUIDs.
Can two different inputs generate the same UUID?
No, each unique combination of namespace and input produces a unique v5 UUID. Same namespace + input always produces identical UUID.
