How to Use the Secure Password & Crypt Key Generator

Generate strong passwords and random cryptographic keys (128/256/512-bit HEX/Base64) locally using window.crypto API.

Updated 2026-06-07. Bluesky Labs tools are designed for browser-local workflows whenever the tool supports local processing.

When to Use This Tool

  • Generating high-entropy passwords for secure account creation
  • Creating 128, 256, or 512-bit cryptographic keys for encryption
  • Producing random Base64 strings for API authentication tokens

Step-by-Step Workflow

  1. Open the tool

    Navigate to the Secure Password & Crypt Key Generator tool page.

  2. Choose settings

    Select your desired key length (e.g., 128, 256, or 512 bits).

  3. Choose settings

    Choose your preferred output format between HEX or Base64 encoding.

  4. Run the action

    Click the generate button to produce the random credential locally in your browser.

  5. Run the action

    Copy the generated string and store it in a secure password manager.

Best Practices

  • Use 256-bit keys for standard production-grade encryption requirements.
  • Never share your generated cryptographic keys with third parties.
  • Store all generated credentials in an encrypted password manager rather than plain text.
  • Generate new keys periodically to maintain high security standards.

FAQ

Is the generation process secure?

Yes, the tool uses the window.crypto API to generate credentials locally in your browser, ensuring the data does not leave your device.

What is the difference between HEX and Base64 formats?

HEX represents data in hexadecimal characters (0-9, A-F), while Base64 encodes binary data into a larger set of printable characters commonly used for web transmission.
