macOS Forensis – Analyze file timestamps in deep

In digital forensics, analyzing timestamps can provide valuable insights into the timeline of events and help reconstruct a digital crime scene. This article focuses on macOS forensics and delves into the analysis of timestamps using a real-world example.

By examining the metadata of a file, specifically the “icon.png.webp” file, we will explore various timestamps and their significance in forensic investigations.

Example

Let’s start by analyzing the metadata of the “icon.png.webp” file using the “mdls” command in macOS, generally located in /usr/bin/mdls.

Simplifying Data Persistence with Property Wrappers in Swift

In modern software development, data persistence plays a crucial role in preserving and accessing user preferences and app state across sessions. With the release of Swift 5.1, a new feature called property wrappers was introduced, which allows developers to encapsulate and automate common behaviors associated with property access. In this article, we will explore how property wrappers can simplify data persistence using a practical example.

Code Example

Let’s consider a scenario where we want to persist various user settings in our app, such as the user’s name, preferred currency, color scheme, profile picture, and the ID of the latest order placed. We can leverage the power of property wrappers to achieve this in a concise and efficient manner.

Add a property wrapper

In this way we add a @Storable property to use in your application.

File Encryption and Decryption in Swift using AES Algorithm

Data security is of utmost importance when dealing with sensitive information. Encryption plays a vital role in safeguarding data from unauthorized access. In this technical blog, we will explore how to encrypt and decrypt files in Swift using the Advanced Encryption Standard (AES) algorithm. We will provide a Swift implementation that demonstrates the encryption and decryption process using a symmetric key.

Final project

This tutorial allow you to create a simple macOS status bar application (with registered file handle: “Open with…”) for crypt and encrypt file, instantly and easily:

AES Encryption and Decryption:

AES is a widely used encryption algorithm that provides a strong level of security. It operates on fixed-size blocks of data and supports key sizes of 128, 192, and 256 bits. AES uses symmetric encryption, meaning the same key is used for both encryption and decryption.

Unlocking the Power of AWS IoT SDK: use MQTT with GPS on iOS


The Internet of Things (IoT) is transforming the way we interact with the world around us. AWS offers a robust suite of services for developing and managing IoT solutions, including the AWS IoT SDK for iOS and Android. In this detailed article, we will explore how to effectively utilize the AWS IoT SDK to create a sample iOS application that leverages MQTT protocol for sending GPS locations.

Prerequisites:

To get started, you will need the following:

  • An AWS account with access to AWS IoT resources.
  • Basic knowledge of iOS development using the Swift programming language.
  • Familiarity with Android development using either Java or Kotlin.

Step 1: AWS IoT Configuration:


Learn how to configure AWS IoT to establish a seamless connection between your devices and the cloud. Follow these steps:

iOS – Secure app sensitive information

Today I want to share a fresh new Swift Package SDK that helps you to hide sensitive informations on your app, like banking apps, in a easy way!

You’ll be notified via callback (optional) when a defined rule occur, and apply the right custom protection you prefer or simply use the integrated blur that cover your app automatically.

Available protections

While writing this post, the SDK provide these protections callbacks:
