Quickstart

I. Understand the Importance of JWT Keys

JSON Web Tokens (JWT) are commonly used to securely transmit information between web applications. JWT keys are crucial for ensuring the security of these tokens. They are used to sign and verify JWTs, preventing tokens from being tampered with or forged, and protecting user data and the security of applications.

II. Generate JWT Keys Using jwtsecrets.com

1. Access the Website: Open your browser and enter https://jwtsecrets.com in the address bar to access the JWT key generator page.

2. Select the Key Length: Locate the "Secret Length" option on the page. There are multiple available values such as 32, 64, 128, 256, and 512 bits. The longer the key, the higher the security level, but it also increases processing costs. Generally, a key length of 128 bits or more can meet the security requirements of most scenarios. Choose an appropriate key length according to your actual application scenarios and security requirements.

3. Generate the Key: After selecting the key length, click the "Generate" button. The system will immediately generate a random JWT key for you. The key will be displayed on the page as a string of characters, for example, "1e253c********************73cee8", with some characters replaced by "*" for security protection.

4. Copy the Key: After generating the key, click the "Copy to clipboard" button, and the key will be copied to your system clipboard. You can then paste it into the configuration file, environment variables, or other places where the key needs to be stored in your application.

5. View the Full Key (Optional): If you need to view the full content of the key, you can click "Show Full Secret". However, please note that for security reasons, be cautious when showing the full key in a public environment or on an untrusted device to avoid key leakage.

III. Use the Generated JWT Key

1. Configure in the Application: Configure the copied JWT key into your application. The specific configuration method varies depending on the type of application and the development framework used. For example, in an application based on Node.js and the Express framework, you might set it in the configuration file like this:

javascript

const jwt = require('jsonwebtoken');
const JWT_SECRET = 'The key you generated';
// Use the key to sign and verify JWTs
function generateToken(payload) {
    return jwt.sign(payload, JWT_SECRET);
}
function verifyToken(token) {
    return jwt.verify(token, JWT_SECRET);
}

1. Perform JWT Operations: In the application, use the configured key to perform operations such as JWT generation and verification. For example, when a user logs in successfully, generate a JWT token using the key, and verify the token in subsequent requests to confirm the user's identity and permissions.

By following these simple steps, you can quickly generate JWT keys on jwtsecrets.com and use them in your application to ensure data security and user authentication. If you encounter any problems during the process, please refer to the relevant documentation or contact technical support.
