Cl0ud Crypt Team - Security Solutions

About Our Team

We are Cl0ud Crypt, a team of cybersecurity enthusiasts and university students dedicated to creating privacy-focused solutions. Our mission is to bridge the gap between security and usability in everyday digital tools.

What started as a final year project has evolved into a series of security tools designed to protect user privacy in the digital era. We believe in transparent, open-source solutions that put users in control of their data.

Our Projects

Live

Cl0udCrypt for Google Drive

A Chrome extension that encrypt any files in AES-256 also upload the files to Google Drive. Your data remains private even if cloud storage is compromised.

AES-256 WebCrypto Chrome API

Beta

Cl0udCrypt for Dropbox

The same zero-knowledge encryption technology adapted for Dropbox users. End-to-end encryption with client-side key generation.

PBKDF2 Dropbox API WebAssembly

Development

Policy Checker

Browser extension that summarizes terms of service and privacy policies, highlighting key points about data collection and user rights.

NLP AI Browser Extension

Project Description

Technology Implemented

JavaScript

Core extension functionality built with modern ES6+ JavaScript

WebCrypto API

Native browser cryptography for maximum performance and security

Chrome APIs

Seamless integration with browser and cloud storage services

PBKDF2

Password-Based Key Derivation Function for secure key generation

Technical Deep Dive

File Selection: User selects files through the browser's native file picker.
Key Derivation: Password processed through PBKDF2-HMAC-SHA256 with 210,000 iterations.
Encryption: AES-256-GCM with 96-bit IV and 128-bit authentication tag.
Metadata Protection: File names encrypted separately with a different key.
Secure Upload: Encrypted files transferred via TLS 1.3 to the cloud provider.
Cleanup: Temporary files securely wiped from memory and storage.

Zero-Knowledge Design

Encryption keys never leave user's device
No server-side component that could be compromised
Mathematically impossible for us to access user data

Memory Protection

Sensitive data wiped immediately after use
Web Workers isolate cryptographic operations
Secure memory allocation practices
