Wtf does this do

This repository contains a working implementation of the AES (Advanced Encryption Standard) encryption algorithm written in Kotlin, a modern programming language that runs on the Java Virtual Machine. AES is one of the most widely used encryption standards in the world. It scrambles sensitive data like passwords, files, or messages into unreadable gibberish that only someone with the correct decryption key can unlock. This repo provides the code needed to encrypt and decrypt data using AES directly within a Kotlin application, without relying on external libraries. The project would be useful for developers building Kotlin applications who need encryption capabilities and either want to understand how AES works under the hood, prefer not to depend on external libraries, or need a lightweight implementation for specific use cases. For example, a developer building a secure messaging app or a tool that encrypts file backups could use this code as a foundation rather than pulling in heavier dependencies. The README itself is quite minimal and doesn't detail the specific features, usage instructions, or which variant of AES the implementation supports (AES has several modes and key sizes). If you're considering using this, you'd want to dig into the actual code to understand what it can do and how to integrate it into your project.
