Your files.
Actually private.
Protect your files from hackers today and quantum computers tomorrow. Enterprise-grade encryption that just works.
Cloud providers can read your files. Ex-employees might still have access.HybridCipher changes that.
The Quantum Threat Timeline
Your files encrypted today with standard encryption will be readable tomorrow.Nation-states are already collecting encrypted data to decrypt later. If your data has value beyond 5 years—personal photos, medical records, financial documents—you need quantum-resistant encryption now.
About HybridCipher
HybridCipher, Inc. is founded by Allen Chen, PhD in Physics, a founder-engineer focused on post-quantum cryptography, long-lived data confidentiality, and cryptographic access revocation for teams.
Keys stay on user devices. The server cannot decrypt your files.
🚫What We Don't Do
- We don't store your encryption keys
Your keys live on your devices—never on our servers
- We don't process unencrypted file contents
All encryption happens client-side before upload
- We don't require internet for local decryption
Access your files offline once keys are synced
Why HybridCipher?
The only file encryption system built for both privacy-conscious individuals and security-demanding teams
Future-Proof Security
Protected for decades, not just years
- Post-quantum cryptography (ML-KEM-768) protects against both current and quantum computing threats
- Enterprise-grade hybrid encryption (X25519 + ML-KEM-768) stays secure for 30+ years
- Zero-knowledge architecture: even the server can't read your files
Effortless Collaboration
Security without compromise
- Add or remove team members instantly—no key management headaches
- Automatic access control: current members decrypt files, removed members can't
- Cross-platform: macOS, Windows, Linux—all devices stay in sync
Zero Trust, Maximum Control
Your keys, your data, your control
- Your encryption keys never leave your devices
- Server is untrusted by design—all cryptography happens client-side
- Verifiable audit trails for membership and key events
Seamless Cryptographic Rekeying
Zero-downtime epoch transitions
- Zero-downtime migration—new epoch activates while old files migrate automatically in background
- Merkle-proven tracking ensures every file transitions to new epochs with transparency logs
- Policy-gated atomic cutover with coverage checks and rollback safeguards
How It Works
Enterprise-grade security with consumer-grade simplicity
Drop your files
Just like any cloud drive—drag, drop, or save files directly to your HybridCipher folder.
No complex setup. No certificates. No key exchanges. Just use it.
Encrypted on your device
Files are encrypted on your device with hybrid quantum-resistant algorithms before they ever leave.
Using NIST-approved ML-KEM-768 + battle-tested X25519. Your encryption keys stay on your devices.
Store anywhere
Store encrypted files in any cloud folder you choose. Storage providers only see encrypted blobs.
Compatible with any cloud folder. No vendor lock-in. Complete privacy.
Share securely
For teams: invite members with one click. They get access. Remove them just as easily.
Automatic rekeying ensures removed members lose access to new encryption epochs.
Audit transparency
Cryptographic audit logs track membership and key events with Merkle commitments.
Audit tooling enables verification and transparency integration.

Cryptographic Accountability
Most "encrypted" drives just promise security. HybridCipher proves it.
Built-in transparency logs
Merkle tree commitments create tamper-proof audit trails
Provable epoch transitions
Track when groups move to new encryption epochs
Out-of-band verification
Safety numbers and fingerprint pinning for extra trust
Audit tooling in development
Reporting workflows are in development
Own Your Privacy
We can't read your files. We can't change them. We can't see who has access. And we can prove it.
Use Any Cloud
Compatible with any cloud folder—use what you trust without trusting it
Open Source Planned
Our crypto code will be fully open and auditable once stable. No security through obscurity, no backdoors
OPAQUE PAKE
Password authentication without ever sending your password to the server—mathematically proven secure
