How does it work?

Currently only basic auth are supported. After you logged in on the web app, you must enter your secret master password, the master password is not stored anywhere, only in your current browser session. You can drag & drop files for upload or click the upload button. Before the upload of your files, the browser will encrypt the file with a AES-GCM 256 bit encryption, then the files will be uploaded. The file content and the filename are saved encrypted on the server. If you download the file, the file will also be decrypted only in your browser after download.

Information about the backend (server side)

The backend of e2ee-cloud use symfony flex and the flysystem php library. Note that the search index db can have a bigger size cause of the encryption. The code is available on GitHub.

Information about the frontend (browser app)

The frontend is based on vue.js. Code coming soon on GitHub.

Further development of the software and bug fixes 

Maintaining and developing new features takes a considerable amount of time. So you can support me here with a recurring pledge to work more time on this project.
$0 of $500 per month
When I reach $500 per month, I'll add a new authentication method. There will also be simple user roles.
