## Encrypted File Transfer Powered by Post-Quantum Security

With quantum computers likely arriving by 2029, mere [end-to-end encryption](/e2ee-encryption/) is not enough to secure your files. Attackers are using the ["Harvest Now, Decrypt Later"](/harvest-now-decrypt-later/) method to store encrypted data which can be later breached using quantum computers. For this reason DragBin uses post quantum encryption (ML-KEM + AES-256) and offers a complete [zero knowledge](/zero-knowledge-encryption/) architecture.

### ML-KEM Key Encapsulation

Quantum-resistant key encapsulation mechanism securing asymmetric key exchanges against future threats.

### AES-256 Encryption

Industry-standard symmetric encryption with 256-bit keys. Your files are encrypted in transit and at rest.

### Argon2 Key Derivation

Winner of the Password Hashing Competition. Securely derives keys from your password with high computational cost.

Using [client side encryption](/client-side-encryption/), the encryption keys always remain with you instead of our server. Nobody, not even DragBin can see your files, links, folders, filenames or passwords that you set. With complete metadata protection in place and more details in our [security whitepaper](/whitepaper.pdf), your data is truly private.
