End-to-end encryption, ready for the post-quantum era.
Encrypt in your browser, with keys that never leave your device — or the HSM. Classical and post-quantum certificates issued by a hardware-anchored CA.

The security that protects a nation, now with you.
We move trust from the server to the math
The server receives and processes files in the clear. A single vulnerability exposes the whole operation.
The server receives only the encrypted package, without the key to open it. Server breached: your data stays protected.
-
Encrypt in the browser
The key is born and stays on your device. The file is encrypted before anything is sent.
-
Store only the encrypted blob
The server keeps only encrypted packages — never the key to open them.
-
Share with proof
Every container has an audit trail: sent, accessed, decrypted — with date and time.
Why CloudCrypt?
Client-Side Encryption
Your files are encrypted in your browser before transmission. Private keys never leave your device.
Post-Quantum Cryptography
ML-KEM-1024 and ML-DSA-87 — the NIST FIPS 203/204 standards. Protect today what must remain secret decades from now.
Keys in Hardware
CA and user keys generated and held in a kNET HSM, or on a KeyGuardian USB token — private keys never exist outside the hardware.
Certificate-Based Trust
Dual certificate chains — classical (ECDSA) and post-quantum (ML-DSA) — rooted in a hardware-anchored Certificate Authority.
Flexible Multi-Factor Authentication
Configurable MFA: Password, TOTP, WebAuthn, Email codes. You choose your security level.
Corporate Control
M-of-N escrow recovery protected by an HSM quorum, delivery tracking and digital signatures on every container.
Built for Security
CloudCrypt uses standardized cryptography: AES-256, ECDH/ECDSA P-256, ML-KEM-1024 and ML-DSA-87 (NIST FIPS 203/204), and Argon2id password hashing. Dual CA chain anchored in an HSM. CloudCrypt is a KRYPTUS product.
