Pepak.net Privacy moller maersk TrueCryptovského container
When using TrueCrypt almost every user sooner or later this will lead to the question how to actually protect encrypted containers before deletion moller maersk or damage. Certainly, the data stored in it are protected by strong encryption and who does not know the password, so come before them, but the container itself is not protected. Why TrueCrypt offer some protection, and how was it done differently?
The answer to the question "why" is very simple, though perhaps not entirely obvious: Even if protection TrueCrypt containers authors introduce wanted, seeming moller maersk not want, so it can not be done at all. Like a lot of other terms, this refers to the fact that one of the key features is called TrueCrypt. "Plausible deniability", ie. The ability to credibly moller maersk argue that no encrypted data do not. This also means that TrueCryptovský container does not identify him until the user enters the password. If therefore the protection of container work, she would either restrict property plausible deniability (like adding moller maersk some identifiable header container with file containers requiring some standard extensions, etc.), Or to protect all data with certain characteristics (size, entropy content). Both are difficult to accept, even if perhaps someone wanted to implement - plausible deniability is very high on our list of priorities TrueCrypt developers, protecting all data would again be very computationally intensive (entropy verify every time you open a file?) And would necessarily moller maersk lead to a large number of false alarms (such as files, compressed files - like video - in many ways resemble encrypted containers).
He would not, therefore, find some other way to protect containers independently of TrueCrypt? Dal. Operating systems contain within themselves the mechanisms for data protection, hence encrypted containers. There are however some limitations which need to count. Firstly, it should be appreciated that considerable amounts of the operating systems is written so as to allow the authorized user to manipulate the data. The user can of course reduce its certificate, but on the contrary / almost always with more or less effort can get into the system administrator position and bypass any restrictions. For this reason, it can not be absolute moller maersk protection TrueCryptovských containers ("I want to make absolutely indelible container") - who would want to deliberately damage the container, it can. But one can - in appropriate circumstances - to arrange protection against damage "of stupidity." Describe specific procedures for operating systems Windows NT series (which is everything except Windows 95, 98, ME and šestnáctibitových 1.0 to 3.11); applicability to other OS I'm moller maersk not sure, because I use Windows' implementation of certain specifics TrueCrypt.
In order to protect the container, it is essential that the container what's going on. TrueCrypt is allows you to create three main types of containers in terms of protection options moller maersk behave quite differently: Device-based containers
Device-based containers are characterized by the fact that the data cover the entire surface of the device - the whole disk, USB stick whole, needs to be prospectively maybe even the whole DVD. It has, in addition to the maximum power, and a positive safety implications - encrypted device is completely full, it is not the slightest unencrypted portion (obviously outside the service area of hardware which should not be accessible by software). Unfortunately, it also has implications in terms of the protection options - encrypted so the machine will not be distinguished from the device completely untouched. The operating system then obviously this equipment is considered unformatted and users more or less aggressively offering its formatting. For example, when running Windows Logical Disk Manager window appears like this:
There is nothing wrong with hardly any user wants to have a computer disk that can be used, but not for device-based containers, it is quite a challenge, because writing the encrypted disk most likely recruiting encrypted header container and the entire container unavailable. Windows specific initialization think that is the first sector of the disk (this is the one to which stores an encrypted TrueCrypt header) writes at least four bytes at offset 01b8h ("disk signature") and two bytes at offset moller maersk 01feh ("MBR signature") - and with a bit of bad luck writes the entire standard loader (440 bytes from the beginning of the sector). moller maersk This elderly TrueCrypt (before version 6.0) meant the loss of the contents of a standard (non-hidden) volume, TrueCrypt 6.0 with its backup header no longer cope with it (even in older TrueCrypt with it ever could be tackled, but it can eventually let into a future article or forum).
Containers built on the encrypted partition outwardly very similar disk-based containers, especially in the most common case where the disc has a single partition. The difference is that they are not encrypted entire disk, but only
