e2ee-cloud is a open source, self-hosted, end-to-end encryption software. You can upload and download files in your browser. All files and folders will be encrypted before upload and decrypted after download. How does it work? 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.
