Quick start

How to generate API keys

Choose prefix and entropy length to create keys.

  1. Step 1
    Set prefix

    Use environment-safe prefixes.

  2. Step 2
    Tune length

    Adjust random body length and count.

  3. Step 3
    Generate

    Copy generated keys into secure stores.

In-depth guide

API key generator

Generate prefixed high-entropy API keys for local development and internal environment seeding.

Format design

Use stable prefixes to distinguish test/live keys and simplify automated validation logic.

Key hygiene

Never commit generated live keys into source control; use secret managers and rotation policies.

When to use it vs alternatives

Use this tool for quick browser-based work when you need an answer or output immediately. Use a dedicated application or automated workflow when you need bulk processing, approvals, or repeatable production rules.

Step-by-step usage

  1. Set prefix — Use environment-safe prefixes.
  2. Tune length — Adjust random body length and count.
  3. Generate — Copy generated keys into secure stores.

Common pitfalls

  • Check the result before replacing the original input.
  • Watch for unit, format, encoding, and browser memory limits on large inputs.
  • Keep a copy of important source material until the output is verified.

Privacy and security

Browser-first by design. The tool page explains any exception before you use it.

Your input is handled in the browser wherever the tool can process it locally. EpitomeTool does not add an upload step unless a tool page explicitly says so.

Frequently asked questions

Can I add a custom prefix?

Yes. Prefix input supports environment tags like sk_test_ or prod_.

How random are generated keys?

Randomness uses browser cryptographic RNG.

Does this store keys?

No. Output is generated in memory and stays in your browser.
