Zero-Knowledge File Storage – Not Even We Can Read It
True zero-knowledge means: if you forget your key, not even we can recover your files. That's not a bug — it's the entire point.
True zero-knowledge means: if you forget your key, not even we can recover your files. That's not a bug — it's the entire point. Law firms, journalists, activists, companies with trade secrets — when you need certainty that no content can be disclosed even under legal pressure, you need zero-knowledge. cryptfiles.cloud can't hand over what we never had.
Why cryptfiles.cloud for Zero knowledge storage
Zero-Knowledge Architecture
We only store encrypted ciphertext. Your plaintext content is technically inaccessible to us – by design.
XChaCha20 End-to-End Encryption
Every file is encrypted client-side with XChaCha20-Poly1305 before it ever reaches our servers. Only you hold the key.
Maximum Privacy by Design
No third-party tracking without consent, no metadata sales, no profiling. Your uploads belong to you.
EU Servers – Stockholm, Sweden
All data stays in the European Union on servers in Stockholm. No critical data transfer to third countries, no US Cloud Act exposure.
For maximum confidentiality needs
Law firms, journalists, activists, companies with trade secrets — when you need certainty that no content can be disclosed even under legal pressure, you need zero-knowledge. cryptfiles.cloud can't hand over what we never had.
Zero knowledge storage - up and running in minutes
Key in your browser
Cryptographic keys are generated exclusively on your device. No network transmission of key material.
Encrypted before upload
Your file leaves your device only as XChaCha20-Poly1305 ciphertext.
Key in the fragment
The key is in the URL fragment (#hash) — per HTTP spec, never sent to any server.
Questions about Zero knowledge storage
Zero-knowledge means the service provider has no technical access to the content of stored data. We manage only encrypted ciphertext — never plaintext.
Technically, no. Without your key (which only you have), our stored data is worthless ciphertext. Even under court order, we have nothing readable to produce.
Yes. The key is in the share link's fragment (#), which per HTTP specification is never sent to any server. Only whoever has the full link can decrypt.
We cannot recover your files — that's not a limitation, it's the guarantee. Keep your link safe. Zero-knowledge is only meaningful when it's absolute.
