Result

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.

Accepted Formats & Rules

  • Bulk generation of UUIDv4, UUIDv7, Hex salts, and Base64 tokens.
  • Timestamp decoder for UUIDv7 identifiers.
  • Environment and configuration syntax builders.

Key Benefits

✓ UUIDv7 Date-Time Decoder: Extract precise millisecond creation timestamps from UUIDv7.
✓ Format Exporter: Exports generated keys formatted as .env files, JSON configs, or YAML lists.
✓ Uniform Entropy: Utilizes browser CSPRNG for high-entropy secure values.

Use Cases

  • • Do you want to generate cryptographically secure salts, API keys, and secret tokens in bulk?
  • • Need to decode a UUIDv7 string and extract the embedded millisecond generation timestamp?
  • • Want to generated secret keys formatted as .env files, JSON configurations, or YAML lists?
