Hey, I made encTitleKeysUpdater.
Just created an account to say, yeah, the .cia itself has no illegal files. The .bin is pulled from a zip online and then is extracted.
Yeah, silly mistake I made. I didn't check for the /freeShop directory, so the file will fail to extract if it doesn't already exist. I'm releasing v1.2 in a day or so though (probably tomorrow, there's just something I want to fix first), so then people should be able to use it to download the .bin before their first launch of freeShop.
