Encrypted partition for sharing поля between Windows and Ubuntu

I recently got в new laptop with one SSD one HDD. I intend to setup в двойственный - boot with Windows and Ubuntu by splitting the SSD in half. However, I would also like to использовал the HDD or at least в part of it эксперт в storage that both operating systems could использовал.

What tools should I использовал? I suppose NTFS is still the only file system that's supported by both, but хан I expect it to work with Ubuntu without problems? And now that TrueCrypt ты существуешь been прекратите, what should I использовал for encryption?
