SHA-1 Hashing

Version 5 UUIDs are generated by hashing a namespace and a name using SHA-1. This provides a more robust and secure deterministic mapping than the MD5-based Version 3.

Standard Namespaces

Use RFC 4122 pre-defined namespaces like DNS, URL, OID, or X.500 to ensure your identifiers follow industry-standard categorization and cross-platform compatibility.

Version 5 Benefits

Collision Resistance (SHA-1)

Deterministic Result Mapping

URL & DNS Scoping Support

Privacy-Preserving Hashing
