I've got Ubuntu 14.04 Desktop and I use Truecrypt to store my confidential files. I've read that since Truecrypt does on the fly encryption, it only stores its decrypted content (and user's password and his keyfile I would think?) in RAM. If it's all true, then does that mean that even if I don't encrypt my swap, there's no risk that my data stored in a Truecrypt container (and my password and a keyfile too?) would end up on a swap partition in an unencrypted form?
