Research direction

Start by reproducing the issue with the linked TrueCrypt samples, comparing the working AES files with the boot and Twofish variants. Check how the example hashes are loaded and tested against those samples. Done means the listed boot and Twofish formats are correctly distinguished where needed and can crack their supplied passwords.
