Free online deterministic UUID v5 generator that hashes a namespace plus name with SHA-1 rules.
How it works
UUID v5 generates a stable UUID based on a namespace UUID and a name using SHA-1. It’s useful when you need reproducible IDs for the same input.
Example
Namespace: DNS (6ba7b810-9dad-11d1-80b4-00c04fd430c8) Name: example.com Output: (deterministic UUID v5)
FAQ
When should I use UUID v5?
Use v5 when you want the same input to always generate the same UUID, such as stable identifiers for known names.
Is SHA-1 secure here?
For UUID v5, SHA-1 is used for deterministic generation, not for cryptographic security. Avoid SHA-1 for security-sensitive hashing.
