 1 | # 🔐 Cipher Calculation App
 2 | 
 3 | A Flutter-based application that enables users to encrypt and decrypt messages using various classical cipher techniques. The app supports:
 4 | 
 5 | - **Rail Fence Cipher**
 6 | - **Hill Cipher**
 7 | - **Caesar Cipher**
 8 | - **Vernam Cipher**
 9 | 
10 | Additionally, it incorporates user authentication (sign-up and login) powered by Supabase.
11 | 
12 | ## ✨ Features
13 | 
14 | - **User Authentication**: Secure sign-up and login functionalities using Supabase.
15 | - **Multiple Cipher Techniques**:
16 |   - **Rail Fence Cipher**: Customise the number of rails for encryption/decryption.
17 |   - **Hill Cipher**: Supports both 2x2 and 3x3 matrix sizes.
18 |   - **Caesar Cipher**: Shift letters by a specified number.
19 |   - **Vernam Cipher**: Implements the one-time pad encryption method.
20 | - **User-Friendly Interface**: Clean and intuitive UI for seamless user experience.
21 | - **Real-Time Results**: Instant encryption/decryption results are displayed upon input.
