What is Encrypted Cloud Storage?
Encrypted cloud storage is a type of cloud file storage where your files are encrypted before they leave your device (client-side encryption). This means the cloud provider cannot read, scan, or analyze your files. Only you hold the encryption keys.
This is fundamentally different from standard cloud storage (Google Drive, Dropbox, OneDrive) where the provider holds your encryption keys and can access your files at any time.
Types of Cloud Encryption
Server-Side Encryption (SSE)
Used by Google Drive, Dropbox, and most providers. Your files are encrypted on the server, but the provider holds the keys. They can decrypt your files for advertising, AI training, or law enforcement requests. This is not true privacy.
End-to-End Encryption (E2EE)
Used by ShadowCloud, Proton Drive, and Tresorit. Your files are encrypted on your device before upload. The server only stores encrypted blobs. Even if the server is compromised, your data remains secure.
Zero-Knowledge Architecture
The strongest form of E2EE. The provider has zero knowledge of your data, your encryption keys, or even your file names. ShadowCloud uses zero-knowledge architecture for maximum privacy.
