ShieldBearer is a cutting-edge npm package meticulously crafted to simplify JSON Web Token (JWT) operations in JavaScript projects. This library stands out by not relying on any external libraries or tools, ensuring a lightweight and efficient solution for secure token handling. ShieldBearer empowers developers to seamlessly sign, decode, and validate JWTs, enhancing the security and reliability of applications.
## Benefits
- **Zero Dependencies:** ShieldBearer doesn't rely on any external libraries or tools, providing a pure and lightweight JWT solution.
- **Efficient Token Operations:** Sign, decode, and validate JWTs with ease, ensuring secure data transmission and authentication.
- **Enhanced Security:** Utilize robust encryption techniques to safeguard sensitive data, bolstering the overall security of your applications.
- **Developer-Friendly API:** ShieldBearer offers an intuitive and developer-friendly interface, allowing for seamless integration and usage.
- **Transparent Codebase:** Explore a well-documented and transparent codebase, enabling developers to understand and customize the library to fit their needs.
## Installation
Install ShieldBearer via npm:
```bash
npm install shieldbearer
```
## Usage
- Require ShieldBearer in your JavaScript file and start harnessing the power of secure JWT operations:
```bash
const shieldbearer = require('shieldbearer');
// Sign a JWT
const token = shieldbearer.sign({ userId: 123 });
// Decode a JWT
const decodedData = shieldbearer.decode(token);
// Validate a JWT
const isValid = shieldbearer.validate(token);
```
## Example
- Here's a basic example of signing, decoding, and validating a JWT using ShieldBearer.
```javascript
const shieldbearer = require("shieldbearer");
// Sign a JWT
const token = shieldbearer.sign({ userId: 123 });
// Decode the JWT
const decodedData = shieldbearer.decode(token);
console.log(decodedData); // Output: { userId: 123 }
// Validate the JWT
const isValid = shieldbearer.validate(token);
console.log(isValid); // Output: true
```
## Improved Security
- You are also able to improve token security by using a secret key to perform operations.
```text
- The secret key works like an ssh encryption, you most have the same secret in both points to ensure success.
```
```javascript
const shieldbearer = require("shieldbearer");
// Sign a JWT
const token = shieldbearer.sign({ userId: 123 }, "secretKey");
// Decode the JWT
const decodedData = shieldbearer.decode(token, "secretKey");
console.log(decodedData); // Output: { userId: 123 }
// Validate the JWT
const isValid = shieldbearer.validate(token, "secretKey");
console.log(isValid); // Output: true
```
