How to Use the API Key Generator
The API Key Generator helps you create strong random keys directly in your browser. It is useful for
developers, app owners, testers, and anyone who needs secure keys for authentication,
API access, services, and internal tools.
To use the tool, choose the key length, set how many keys you want to create, and select a
format such as hex, alphanumeric, Base64, Base64URL, UUID, or a custom character set.
You can also add a prefix like sk_ or api_, include a suffix,
and split the key into groups for better readability.
This tool uses the browser’s cryptographically secure random generator, which means the keys are
produced locally on your device instead of being generated with weak random logic. That makes it a practical option
for generating tokens, secret-like identifiers, testing keys, and temporary credentials.
What Can This Tool Generate?
Hex keys for tokens and secret strings
Alphanumeric keys for apps and services
Base64 and Base64URL keys for web-safe use cases
UUID keys for unique identifiers
Custom charset keys for specific formatting needs
Bulk key generation for teams and testing

Important Note
While this tool generates strong random keys, production secrets should always be stored securely using trusted
secret management practices. Never expose live private keys in frontend code, public repositories, or screenshots.
Frequently Asked Questions (FAQ)
Yes. This tool uses the browser’s cryptographically secure random generator to create keys.
That is much better than simple random functions for generating secure identifiers and tokens.
You can generate hex, alphanumeric, Base64,
Base64URL, UUID, and custom charset API keys.
Yes. Just set the Number of Keys field and the tool will generate all of them instantly.
This is useful for testing, staging environments, or creating multiple credentials quickly.
Base64URL is a URL-safe version of Base64. It replaces characters like +
and / with safer alternatives, making it more convenient for URLs, JWT-related values,
and web-based systems.
No. The keys are generated directly in your browser, and this tool does not need to upload them anywhere
for generation. That helps keep your keys private on your device.
