bedrock-jwt

A Rust library for verifying JWT tokens for Minecraft: Bedrock Edition.

This library provides functionality to verify the authenticity of a chain of JWT tokens provided by a client, ensuring that the player’s identity is valid and trusted.

Features

• JWT chain verification
• Player data extraction
• Public key handling from Base64 encoded strings

Usage

Add this to your Cargo.toml:

1
[dependencies]
2
bedrock-jwt = { git = "https://github.com/harihar-nautiyal/bedrock-jwt.git" }

The primary entry point for this library is the verify_chain function, which takes a slice of JWT tokens and a Mojang public key to perform verification.

1
use bedrock_jwt::verifier::{verify_chain, PlayerClaims};
2

3
fn main() {
4
    let tokens = vec![
5
        "first_jwt_token",
6
        "second_jwt_token",
7
        "third_jwt_token",
8
    ];
9
    let mojang_public_key = "your_mojang_public_key";
10

11
    match verify_chain(&tokens, mojang_public_key) {
12
        Ok(claims) => {
13
            println!("Successfully verified player: {}", claims.display_name);
14
        }
15
        Err(e) => {
16
            eprintln!("Verification failed: {}", e);
17
        }
18
    }
19
}

Building

To build the library, run:

cargo build

Running the example

The main.rs file contains an example of how to use the library. It reads the JWT tokens and the Mojang public key from standard input and then verifies the chain.

To run the example:

cargo run

Then, paste the three JWT tokens, each on a new line, followed by the Mojang public key on a new line.
