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:
