How is this different from the Password Generator?

The Password Generator uses a human-typable charset (letters, digits, symbols), while this tool generates Hex, Base64, or UUID tokens meant for systems, such as API keys and session secrets.

Is the length measured in bytes?

Yes. It generates a cryptographically secure random value with the specified number of bytes, then encodes it in the chosen format. For example, 32 bytes becomes 64 characters in Hex or about 43 characters in Base64.

Is the generated value stored on a server?

No. It's generated entirely in your browser using crypto.getRandomValues.

🎫 Random Token/Secret Generator

Generate API keys, session secrets, and test tokens in Hex, Base64, Base64URL, or UUID format.

Format Length (bytes): 32

How to use

Choose a format (Hex/Base64/Base64URL/UUID) and length.
Click "Generate New".
Use the copy button to grab it instantly.

🎯 Use Cases

Issue API keys or secret keys — generate a random key to register with a service
Session or CSRF token test values — when you need a temporary token during development
Generate unique identifiers (UUIDs) — for DB records or transaction IDs

Example

Input

Format: Base64URL, Length: 32 bytes
Random bytes (hex): 3fa20c917b4e68d502ff1a6c88e3409b
                5d27b0c416fea933740d8e52c16bafd0

Output

Encoding a 32-byte (256-bit) random value as Base64URL yields a 43-character string with no +/= characters. It can be dropped straight into URLs, cookies, or headers, making it ideal for API keys and session secrets.
