unbreak (hackage): unbreak is a secure remote file storage utility written in Haskell.  Other than a working SSH server and an empty directory, it requires no configuration on the server-side to set up the file storage. Leveraging existing commands, it simplifies the process of fetching and saving files with a client-side encryption. It aims to make the work flow natural, as if the user is using an unencrypted local file, while keeping the local-remote interaction as rare as possible to be usable even with a highly unstable Internet connection.  unbreak uses modern crypto primitives such as scrypt and ChaCha20-Poly1305 to protect user security and privacy. Some of its usage is documented in the Unbreak.Crypto module. The API is internal and you should not directly depend on them from your code, but browsing the source code from the API docs and copying them to adapt to another free software is highly encouraged.
