Would you mind sharing it, so that other people don't have to go through the same pain you did? Maybe even creating an issue and dropping the code there could be helpful. Then somebody could pick it up and reuse the algorithms you wrote.
Caveat that it doesn't emit a csv you can import elsewhere, it's not extremely polished, hasn't ever been run outside of my laptop, just does a bunch of unnecessarily clever things. Needs the 1password commandline utility `op` set up (ie you have to have told it your secret key already).
It'll create `items/` and `documents/` dirs with one file per, well, item or document, named after the uuid. It tries to make a symlink named after the metadata for each file in the hope that you'll have an ok time tabcompleting your way to the desired secret. There's some attempt to not redownload files that you already have, mostly because I re-ran this thing a million times trying to get it to work.
I wrote this to be able to zip all my secrets, `scrypt` the zip file with a strong password, and put the scrypted file on a usb drive that isn't particularly well hidden, just as another fallback/recovery option in case a meteor hits 1password HQ or my paper backups catch fire.
That'd be pretty great.
