FileSender UX ZIP

Encrypted multi-file streaming

FileSender is an open source web application for sending files of any size, quickly and securely. The sender has full control over who receives and can access the files and for which period of time – as it should be. This project aims to create a major update to the user interface of FileSender: the software offers End-to-End encryption for sending one or more files in a transfer. Because encryption is done in the browser the server can not offer an archive containing all of the files for an entire transfer. Decryption must happen in the browser and so any archive containing the decrypted files must be created in the browser. This build on the recent streaming decryption support to allow zip64 files to be created containing selected files from an encrypted transfer. The content will be decrypted in the browser prior to being streamed to the zip64 archive. There will be additional effort to improve overall performance, stability and security.
