No idea. What about doing an offset with LVM first and then zero offset for LUKS? > Reason for doing this is an attempt at having a detached LUKS header > capable of unlocking a VeraCrypt volume since > unlocking a VeraCrypt volume takes too long and its annoying. Oh, yes. I did complain to them, never got an answer. I plan to move my Windows machine back to the last Truecrypt, since the one known vulnerability seems not to affect single-user machines anyways. Currently I am attaching 8 zeros to the pasphrase, so I can unlock my high-entropy passhrase with iteration 10 and not wait 70 seconds in VeraCrypt. Somebody there really has no clue why usability is important and that users should be able to ovverride most things. They may just know more than the developers about their application scenario... Does anybody know what the status of CipherShed and TCnext is and whether they have more of a clue?
