Uncaught Error: ASN.1 error: PEM error: PEM Base64 error: invalid Base64 encoding

Describe the bug when using the mineflayer with deno instead of node it resolves in a Error Steps to Reproduce

1. Create a script with the contents

import mineflayer from 'npm:mineflayer';

const bot = mineflayer.createBot({
  username: 'bot',
  host: 'localhost',
  version: '1.20.1',
  port: '2555',
});

bot.on('inject_allowed', () => {
  console.log('Inject allowed');
});
bot.on('login', () => {
  console.log('Succesfully logged in!');
});
bot.on('spawn', () => {
  console.log('Succesfully spawned in!');
});

2. Execute the command

 deno run --allow-all index.js

3. See error

Expected behavior

Inject allowed
Succesfully logged in!'
Succesfully spawned in!'

Environment

• OS: Windows 11
• deno version: 1.36.4
• std version: 0.195.0

The following code has same problem

import crypto from "node:crypto"
import { Buffer } from "node:buffer"

  let publicKey = `XXXX`
  let rsaKey = {
    key: publicKey,
    padding: crypto.constants.RSA_PKCS1_PADDING,
  }
  let buffer = Buffer.from(toEncrypt, "utf8")
  let encrypted = crypto.publicEncrypt(rsaKey, buffer)

error info:

error: Uncaught (in promise) Error: ASN.1 error: PEM error: PEM Base64 error: invalid Base64 encoding
  let encrypted = crypto.publicEncrypt(rsaKey, buffer)

This is a bug in node-minecraft-protocol package. node-minecraft-protocol generates PEM of non-standard 65-character lines.

Deno follows the rfc7468 PEM strictly.

Generators MUST wrap the base64-encoded lines so that each line consists of exactly 64 characters except for the final line, which will encode the remainder of the data (within the 64-character line boundary), and they MUST NOT emit extraneous whitespace.

I've opened a PR on the node-minecraft-protocol repo to fix the generator bug: https://github.com/PrismarineJS/node-minecraft-protocol/pull/1292
