UUID v5 Generator
Generate version 5 UUIDs (name-based UUIDs using SHA-1) instantly. These UUIDs are created by hashing a namespace identifier and name, providing a more secure alternative to version 3 UUIDs.
Bulk UUID Generation
Enter the number of UUIDs to generate and download them as a text file. Ideal for batch processing and data management tasks.

About UUID Version 5
What is UUID v5?
UUID version 5 generates name-based UUIDs using SHA-1 hashing. Similar to version 3, it takes a namespace identifier and name as input, but uses a more secure hashing algorithm. This makes it ideal for applications requiring both deterministic IDs and enhanced security.
Advantages of UUID v5
Enhanced SecurityUses SHA-1 for more secure hash generation
DeterministicConsistent UUIDs for same inputs
Name-BasedMeaningful identifiers from names
Collision ResistantHigher collision resistance than v3
Best Use Cases
- Security Applications:Perfect for applications requiring secure deterministic IDs
- Content Hashing:Ideal for generating content-based identifiers
- Domain-Specific IDs:Great for creating domain-specific unique identifiers
- Data Integrity:Excellent for verifying data integrity across systems
