You can now use mooltipy (v0.5.1+) to store API keys as data contexts (allowing more than 31 characters) and retrieve them to stdout in a script or on the command-line.
See my post to Google Groups for an example of how it works.
all 3 keys need to be pressed at once.
We indeed document mc-cli as it isn't officially part of the mooltipass eco-system. You may however come talk to its creator on our IRC channel on freenode.net: #mooltipass
Ok, I've just read this post: https://www.reddit.com/r/mooltipass/comments/66ummw/export_to_csv/
So do I have to buy something like this: https://www.amazon.com/Microsystems-Smart-Card-Reader-SCR3310V2/dp/B002N3MM6W/ insert my card, that get the message "Unknown Card", get the script and through that my encryption key and my data?
