## Overview

Alexandria is a small WPF encryption app. The user enters text or encoded numbers and a 2×2 key in the window; the window dispatches encryption or decryption, then displays intermediate numbers and the result. Encryption converts supported characters to numbers before applying the key matrix; decryption parses numbers, applies the inverse matrix, then converts values back to characters. MatrixHelper supports inverse-matrix calculation and multiplication. The README gives no further capabilities, and the sampled files do not establish additional UI or startup wiring.

Main entry points: [`Verschluesselung.cs`](https://github.com/cavkev/alexandria-encryption-software/blob/main/Verschluesselung.cs) (Text cipher), [`MainWindow.xaml.cs`](https://github.com/cavkev/alexandria-encryption-software/blob/main/MainWindow.xaml.cs) (Main window), [`MatrixHelper.cs`](https://github.com/cavkev/alexandria-encryption-software/blob/main/MatrixHelper.cs) (Matrix helper)
