Oh, JavaScript is a pain in the neck! But, if you perceive with it, it pays dividends. Here's an example with no page refreshes, and where JavaScript catches user input and then updates the required fields:

Ever worried about storing sensitive data like JWTs in localStorage or sessionStorage? I’ve been there too, especially when thinking about the risks in production.
That’s what led me to create Shield-Storage – a simple NPM package that encrypts your data with AES before storing it. It’s my way of solving a problem I faced and helping others avoid the same concerns.
The best part? It supports both JavaScript and TypeScript, making it easy to integrate into any project.
If this sounds like something you’d find useful, check it out here:

Or simply use,
npm i shield-storage
#npm
#localstorage
#sessionstorage

Cracking some
acme.corp
user hashes? It's dangerous to go alone; Take 𝗣𝗮𝘀𝘀𝗴𝗲𝗻 to generate candidates like “Acme.corp2024” or “Acme.corp2024!”! 💡
Do you know that
weakpass.com
has its repository
https://lnkd.in/eGrzWuGi
with a list of JavaScript tools and other stuff that can assist with hash cracking and related tasks (for anyone who chooses JavaScript for this!)?
Let’s look at some of these tools, one at a time.

𝗣𝗮𝘀𝘀𝗴𝗲𝗻 generates wordlists based on words provided by the user. For instance, a common problem is that some corp-users create passwords using their company’s name with simple additions, like “𝗔𝗰𝗺𝗲𝟭𝟮𝟯”, or set up service passwords in the same manner. With 𝗣𝗮𝘀𝘀𝗴𝗲𝗻, you can easily generate targeted wordlists, applying various rules to create options that match a specific target.

? Why not generate candidates like “Acme.corp2024” or “Acme.corp2024!”?
You can choose either your own rules or use one of the predefined ones, such as best64, nsa64, and hob064.
𝗣𝗮𝘀𝘀𝗴𝗲𝗻 utilises the 𝗵𝗮𝘀𝗵𝗰𝗮𝘁-𝗿𝘂𝗹𝗲𝘀-𝗷𝘀 library, a JavaScript implementation of the hashcat rules engine. You can also install it directly via npm: npm install hashcat-rules-js

🔒 Quick Revision — bcryptJs! 🔒
Let's talk about salting and hashing passwords using
bcrypt.js
in JavaScript. Protecting user data is crucial, so here's a quick guide:
1️⃣ Salting and Hashing: 🧂🔑
1. Salting adds random data to passwords before hashing to ensure unique hashes.
2. await bcrypt.genSalt(10); generates a salt with 10 rounds, enhancing security by making the hashing process slower.
3. Hashing converts passwords into a fixed-length string of characters, which is not reversible.
4. bcrypt automatically handles salting and hashing, making it easier and more secure.
5. Always store the hashed password, not the plain one.
Stay secure and keep your user data safe! 🚀 Feel free to ask questions or share your thoughts below! Let's keep learning together! 💡

📢 Understanding bcryptjs: Security for Your Passwords 🚀
When it comes to system authentication, protecting user passwords is essential. This is where bcryptjs comes into play—a powerful library in the JavaScript/
Node.js
ecosystem for password encryption.
🔒 What is bcryptjs?
bcryptjs is a pure JavaScript implementation of the bcrypt algorithm. It’s used for hashing passwords, meaning it transforms passwords into an encrypted format that cannot be directly reversed, enhancing security.
🛡️ Why use bcryptjs?
* Advanced security: Uses the bcrypt algorithm, including a salt feature to generate unique hashes, even for identical passwords.
* Configurable rounds: Allows you to adjust the computational cost of hashing, balancing security and performance.
* Cross-platform: Since it’s pure JS, it works on any
Node.js
environment, without native dependencies.
🚀 How to use bcryptjs?
const bcrypt = require('bcryptjs');
// Creating a password hash
const password = "mySecurePassword123";
const saltRounds = 10;
bcrypt.hash
(password, saltRounds, (err, hash) => {
if (err) throw err;
console.log
("Password Hash:", hash);
// Verifying the password
bcrypt.compare
(password, hash, (err, res) => {
if (err) throw err;
console.log
("Is the password valid?", res);
📌 Practical tips:
* Always use salt! bcryptjs handles this automatically.
* Never store passwords in plain text. With bcryptjs, only hashed passwords are stored.
* Update the rounds over time. As hardware evolves, increasing the number of rounds helps maintain security levels.
🤔 bcrypt vs bcryptjs?
* Use bcryptjs when you need a pure JS solution (no native dependencies).
* Prefer bcrypt for better performance if native libraries are an option in your environment.

In the fast-paced world of technology, new tools quickly grab attention. Bun is one such tool in the JavaScript community, positioning itself as a faster alternative to
Node.js
. But is Bun ready for critical production applications?
Bun is a modern JavaScript runtime like
Node.js
or Deno, focused on speed. It's a complete toolkit for compiling, installing, and running code efficiently. While
Node.js
is reliable like a luxurious SUV, Bun is a sports car with speed and performance.
However, consideration is needed before adopting Bun in production environments.
Node.js
has a strong reputation, similar to a seasoned caddy. With over a decade of use, a vast community quickly addresses vulnerabilities. Conversely, Bun is new, with fewer contributors, meaning potential vulnerabilities might go unnoticed longer, posing security risks.
The supporting ecosystem is critical.
Node.js
has a rich library of packages built over the years, offering extensive functionalities. Bun's ecosystem is still developing, making it risky for projects needing diverse tools.
Community support also matters.
Node.js
benefits from corporate commitment from IBM, Microsoft, and Joyent, providing ideas and security patches.
Despite its thrilling performance improvements, caution is advised with Bun. Testing it in non-critical environments is essential to assess its stability and security before using it for high-profile applications.
For projects where performance is crucial and some risk is acceptable, Bun could be considered. But for mission-critical applications requiring security and reliability,
Node.js
remains the safer choice.
Bun is an exciting new option that may become a stellar production tool. For now, proceed with thoughtful experimentation rather than full deployment in sensitive scenarios.
