About uppy
Uppy is an MIT licensed, TypeScript built, modular JavaScript file uploader for web browsers that drops into any web application, aimed at developers who would rather wire up plugins than build file uploading from scratch.
About cryfs
CryFS is a FUSE based cryptographic filesystem written in Rust that encrypts a vault directory so it can be stored safely in cloud services such as Dropbox, iCloud, or OneDrive, and it is intended for Linux users who want their file contents, file sizes, directory structure, and metadata hidden from the storage provider rather than encrypted one file at a time.
