🗂️ Distributed File Storage System

A distributed file storage system built in Golang, designed for efficient, secure, and scalable peer-to-peer (P2P) file storage and retrieval.
This system ensures data integrity, encryption, and optimized storage using a content-addressable storage (CAS) model.

🚀 Features

🔗 Peer-to-Peer Architecture

• Fully decentralized file sharing using a TCP-based transport layer.
• Each peer can act as both a client and server, supporting dynamic participation.

🧩 Content-Addressable Storage (CAS)

• Implements SHA-1 hashing for deterministic file identification.
• Guarantees deduplication and efficient lookup of files by content hash.

🔒 Secure Encryption

• Files are AES-encrypted before distribution.
• Supports key-based decryption, ensuring confidentiality and controlled access.

⚙️ Fault Tolerance & Scalability

• Allows multiple nodes to store and retrieve chunks of data.
• Resilient to node failures and supports horizontal scalability as peers join or leave the network.

📁 Optimized Storage Management

• Structured file path transformation for organized storage.
• Efficient deletion and cleanup mechanisms to maintain system health.
