Crack Wireless Passwords Using A Raspberry Pi And Aircrack

Another day and another project with one of the many Raspberry Pi devices that are laying around my house. One of my younger family members came over to try to get inspired for his college future so we decided to work on a project together. We wanted to explore some cybersecurity topics rather than programming which led us to network security.

We decided to try to obtain the password to my wireless network password using the popular Aircrack-ng software. While it didn’t find my password in the end, it doesn’t mean we weren’t successful.

In this tutorial, we’re going to see how to setup Aircrack-ng on a Raspberry Pi to decipher WiFi passwords for WEP and WPA secured networks.

Encrypt And Decrypt Data In A Golang Application With The Crypto Packages

Being able to encrypt and decrypt data within an application is very useful for a lot of circumstances. Let’s not confuse encryption and decryption with hashing like that found in a bcrypt library, where a hash is only meant to transform data in one direction.

Not too long ago I wrote about in a previous article how to encrypt and decrypt data using Node.js. This was partially inspired by me learning how to build software wallets for cryptocurrencies and encrypting the sensitive information. However, what if we wanted to use Go instead of Node.js?

We’re going to take a look at encrypting data and then decrypting it within a Go application by using the already available crypto packages.

Encrypt And Decrypt Data In Node.js With The Crypto Library

As you’ve probably noticed from the previous few articles, I’ve been doing a lot of development around cryptocurrency wallets using Node.js. Up until now, I’ve only been writing about interacting with different currencies. However, I haven’t discussed how to safely store your wallet information.

When it comes to storing anything sensitive, whether it be cryptocurrency secrets or something else, you must do so safely and securely. For example, the data must be encrypted at rest and decrypted when used.

We’re going to see how to encrypt data with a passphrase using Node.js and decrypt it using that same passphrase when necessary.

Build A Password Manager For Android And iOS Using Ionic 2

Have you ever wanted to build your own password manager? Maybe you don’t trust the password management tools that already exist, or maybe you just want the experience. I personally use the tool 1Password, but many of my friends don’t trust the applications that exist on the market. It is a valid concern that they have. What if the password managers that exist are using an ancient or obsolete DES specification or similar, rather than the modern AES? What if the master passwords are not being hashed with a strong Bcrypt algorithm?

Not too long ago we created a password manager using the NativeScript framework, but what if we wanted to build one with a different technology.

We’re going to see how to build a password manager that makes use of the AES specification using Ionic 2 and Angular. This application will work for both Android and iOS and look great on both.
