## Introduction📘
The Caesar Cipher Tool is a web-based application that demonstrates one of the earliest encryption techniques known as the Caesar Cipher. This tool enables users to encrypt and decrypt messages using a simple substitution cipher, where each letter in the plaintext shifts by a set number of positions along the alphabet. This project provides a hands-on experience in understanding basic encryption concepts and their role in cybersecurity.
## Technical Description⚙️
The Caesar Cipher implementation includes both letter and number shifting capabilities:
- **Letter Shifting**: Each letter is shifted by the specified key value while preserving case:
```javascript
let code = char.charCodeAt(0);
let baseCode = char === char.toUpperCase() ? 65 : 97;
code = (code - baseCode + shift) % 26 + baseCode;
```
- **Number Shifting**: Numbers are shifted cyclically through 0-9:
```javascript
char = String.fromCharCode((char.charCodeAt(0) - 48 + shift) % 10 + 48);
```
The tool automatically handles special characters and spaces by leaving them unchanged, ensuring message formatting is preserved.
## Technologies Used💻
- **HTML5**:
- Semantic structure with clearly organized sections
- Form controls for encryption settings
- Responsive textarea elements for input/output
- **CSS3**:
- Flexbox layout for responsive design
- Google Fonts integration (Roboto)
- Modern styling with transitions and shadows
- Color scheme featuring #0F9D58 as primary color
- **JavaScript**:
- Event listeners for real-time interface updates
- Input validation and error handling
- Clipboard integration for copying results
- Dynamic heading updates based on mode selection
## Main Features🌟
