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
RFC 4122 Best Practice
Cross-Platform Consistency
