In-Depth Guide

Everything you need to know

A UUID Version 5 is similar to Version 3 but uses SHA-1 as the hashing algorithm. It is the preferred choice for deterministic IDs because SHA-1 has fewer known collision vulnerabilities than MD5.

Standard Namespaces:

  • DNS: For domain names (used by default).
  • URL: For full web addresses.
  • OID: For ISO object identifiers.
