Open-source stealth USB hides an encrypted partition behind an 8GB decoy drive Phantom Drive appears as a regular USB stick until you create a text file to unlock the hidden data

Why not just use veracrypt?

That’s what I would go with if I was inclined. Create a volume the size of the drive and add a hidden volume with a different password within like we’ve been doing for years (decades at this point maybe almost).

I would upload encrypt file somewhere and download it when needed. If you’re worried someone will actually access your USB stick looking for encrypted data, why carry it at all? It’s cool if you want to pretend you’re a spy or something but it’s not very practical.

That’s assuming that wherever you are going to or coming from has an internet connection. It’s likely that there will be a connection, but it’s still not a guarantee. And if there is a connection, the size of the files you’re carrying may make using that connection impractical.
