    Looks like this whole thing was motivated by the fact that, in order to get the encrypted PDF in a Buffer like they wanted, they had to save to disk and load it back. They could have instead used an in-memory filesystem such as https://github.com/streamich/memfs and just made the existing PDF library that was almost right use that.
