UUID / GUID Workstation
Generate and inspect cryptographically secure RFC 9562 identifiers (UUIDv4 & time-sortable UUIDv7) client-side.
UUIDv4 vs UUIDv7
v4 provides 122 bits of uncoordinated randomness—ideal for secrets and public tokens. v7 embeds a 48-bit millisecond timestamp, creating chronological order that stops database B-Tree index fragmentation.
RFC 9562 Compliance
Published in May 2024, RFC 9562 formally replaced the 2005 RFC 4122 specification. All generation and inspection routines follow strict RFC 9562 bit layouts and variant bounds.
Zero Network Exposure
Identifiers are synthesized within the local browser runtime via crypto.getRandomValues(). No IDs are transmitted over networks or recorded.
