# Base64 Encoder/Decoder

Simple command-line base64 encoder/decoder written in C.  

  

This project was created to familiarize myself with:

- Parsing command-line arguments

- File input/output

- Error handling

- Binary data manipulation and bitwise operations

- Understanding base64 in web development

## Demo

## base64enc.c

- Converts binary/text data to base64 encoded format

- Wraps output at 76 characters per line

- Handles padding with '=' characters as needed

## base64dec.c

- Decodes base64 encoded data back to original format

- Validates input format and padding

## Installation

```bash

make # Build both encoder and decoder

make clean # Remove generated files

```

## Usage

**Encoding**

```bash

./base64enc [FILE]         # Encode file to base64

./base64enc < input.txt    # Encode from stdin

```

**Decoding**

```bash

./base64dec [FILE]         # Decode base64 file

./base64dec < encoded.txt  # Decode from stdin

```
