I made a 100% open source encrypted USB drive with a stealth mechanism to hide its second partition. To decrypt it you must create a file called password.txt containing your password, this is used to derive a AES-256 key. The drive automatically unmounts itself, remounts the remaining disk and encrypts and decrypts in place.

This is for privacy advocates, journalists, people living in dangerous countries, and open source hardware enthusiasts.

A hardware-encrypted USB drive that presents a decoy 8 GB FAT32 partition by default. A hidden, larger encrypted partition (21 GB) is only revealed by writing a special file containing a password to the visible drive. Once the correct password is written, the FAT32 partition is unmounted and replaced with the encrypted volume, with all data encrypted in place using the provided key.
