Security that starts
before your files leave your device.

XORS combines zero-knowledge architecture, client-side encryption, and post-quantum cryptography to keep your data private today and resilient against tomorrow's threats.

Features

Everything sensitive data demands

Built for developers, researchers, and organizations with long-term confidentiality requirements.

Hybrid encryption

AES + ML-KEM

AES-256-GCM encrypts your files. ML-KEM wraps the key. Fast symmetric encryption guarded by quantum-resistant key encapsulation.

Zero plaintext storage

Client-side only

Files are encrypted before leaving your device. Cloudflare R2 only receives ciphertext. Even we cannot read your files.

Self-destruct files

TTL + count limit

Set files to auto-delete after a time limit or download count. MongoDB TTL handles deletion automatically, server-side.

Cryptographic audit trail

SHA-256 chained

Every action logged with a SHA-256 chained audit trail. Each entry signs the previous one — tamper-evident by design.

Quantum security score

0–100 scoring

Every file gets a score based on encryption type, integrity hash, sharing status, and self-destruct settings. Know your risk at a glance.

Tamper detection

GCM auth tag

AES-GCM authentication tag detects any modification to encrypted files. SHA-256 hash provides an additional integrity check.

Encryption pipeline

4 steps. Zero trust required.

01

You upload

Select any file. We accept any file type up to 100 MB. Nothing is transmitted yet.

02

AES-256 encrypts

A fresh 256-bit key is generated. Your file is encrypted in-browser using AES-256-GCM with an auth tag.

03

ML-KEM wraps key

The AES key is encapsulated with ML-KEM. The raw key never touches the server.

04

Stored securely

The encrypted file and the wrapped key are stored separately. Even a full server compromise yields nothing readable.

Security standards

Only NIST standardized cryptography

We do not use experimental or unvetted algorithms. Every primitive in this stack has been standardized by NIST.
