🔐 Base64 Conversion Algorithm

This repository contains a C implementation of the Base64 encoding algorithm, developed as an exercise to practice bitwise operations and data encoding, in preparation for the Computer Networks exam (UNIPD).

📌 Project Description

Base64 is a widely used encoding scheme that represents binary data in an ASCII string format.
This project manually implements the conversion logic without relying on external libraries, focusing on:

  • Bitwise operations
  • Left-shift manipulation
  • Grouping binary sequences
  • Handling padding (=)

🚀 Usage

1. Compile the program

gcc base64.c -o base64

2. Run with a string to encode

./base64 "Hello"

3. Example Output

SGVsbG8=

📚 Learning Goals

  • Practice C programming for low-level data handling.
  • Gain hands-on experience with bitwise operations.
  • Understand how Base64 encoding works internally.
  • Prepare for Computer Networks exam (UNIPD) by exploring encoding/decoding mechanisms.
