About this tool
This page opens the secrets generator with UUID v7 already selected — choose the count and format, then copy the freshly generated identifiers.
UUID v7 leads with a 48-bit millisecond timestamp, so newly generated values sort chronologically — a great fit for database primary keys and event logs where insert order matters. The remaining bits are still cryptographically random, and this tool can decode the creation time back out of any UUID v7.
The full tool also generates UUID v4, hex salts and Base64 tokens and exports to .env, JSON and YAML — everything runs locally in your browser, nothing touches a server.
Example. A requested API key is filled from crypto.getRandomValues, and a UUIDv7 is decoded to the millisecond timestamp stored in its first bits.
Limit. Millisecond extraction applies to UUIDv7 only; a version-4 UUID has no embedded time to decode.
