beam-splitter
cli tool that encrypts a file & splits it into chunks, also re-assembles chunks using a password. This is useful for me and designed to work on a specific (and quite low) version of node. Comments, PRs and suggestions are welcome.
usage
beam-splitter --export demo.zip --password pass
beam-splitter --import ./demo.zip_output --password pass
how does it work?
exporting
You supply a password, the file is encrypted using node built in streaming crypto API and the blowfish algorithm. The encrypted blob is then split into 1MB chunks and put into a folder using the .png extension so it appears to be a folder of seemingly broken images.
importing
You supply a folder and password and it re-assembles the file and decrypts it.
example output
beam-splitter :: importing .\demo.zip_output\
