Result

This page opens the secrets generator with the 256-bit Base64 token type already selected — set the count, pick a format and copy the result.

Each token packs 256 bits of CSPRNG entropy into a compact Base64 string — noticeably shorter than hex at the same strength, which makes it a natural fit for API keys, refresh tokens and secret values in configuration files.

The full tool also generates UUID v4, UUID v7 and hex salts, exports to .env, JSON and YAML, and decodes UUID v7 timestamps — all locally in your browser, with no server involved.

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?
