TrueCrypt 6.1 erschienen

TrueCrypt ist eine Open-Source-Software zur real-time OTF (on-the-fly) Verschlüsselung von Festplatten, Wechselmedien oder zur Erstellung verschlüsselter Partitionen oder versteckter Container (Hidden Volumes).

Mit TrueCrypt 6.1 wurde eine neue Version veröffentlicht, die folgende Änderungen mit sich bringt:<ul><i>October 31, 2008

<b> New features:</b>

* Ability to encrypt a non-system partition without losing existing data on the partition. (Windows Vista/2008)

Note: To encrypt a non-system partition in place, click 'Create Volume' > 'Encrypt a non-system partition' > 'Standard volume' > 'Select Device' > 'Encrypt partition in place' and then follow the instructions in the wizard. Please note that this is not supported on Windows XP/2000/2003 as these versions of Windows do not natively support shrinking of a filesystem (the filesystem needs to be shrunk to make space for the volume header and backup header).
* Support for security tokens and smart cards (for more information, see section Security Tokens and Smart Cards in chapter Keyfiles).
* The TrueCrypt boot loader can be prevented from displaying any texts (by selecting Settings > System Encryption and enabling the option 'Do not show any texts in the pre-boot authentication screen').
* The TrueCrypt boot loader can now display a custom message (select Settings > System Encryption and enter the message in the corresponding field) either without any other texts or along with the standard TrueCrypt boot loader texts.
* Pre-boot authentication passwords can now be cached in the driver memory, which allows them to be used for mounting of non-system TrueCrypt volumes (select Settings > System Encryption and enable the option 'Cache pre-boot authentication password').
* Linux and Mac OS X versions: The ability to mount a Windows system partition encrypted by TrueCrypt and to mount a partition located on a Windows system drive that is fully encrypted by a Windows version of TrueCrypt.


<b>Improvements:</b>

* Protection against memory corruption caused by certain inappropriately designed versions of some BIOSes, which prevented the pre-boot authentication component from working properly.
(Windows Vista/XP/2008/2003)
* During the process of creation of a hidden operating system, TrueCrypt now securely erases the entire content of the partition where the original system resides after the hidden system has been created. The user is then prompted to install a new system on the partition and encrypt it using TrueCrypt (thus the decoy system is created).

Note: Although we are not aware of any security issues (connected with decoy systems) affecting the previous versions of TrueCrypt, we have implemented this change to prevent any such undiscovered security issues (if there are any). Otherwise, in the future, a vulnerability might be discovered that could allow an attacker to find out that the TrueCrypt wizard was used in the hidden-system-creation mode (which might indicate the existence of a hidden operating system on the computer) e.g. by analyzing files, such as log files created by Windows, on the partition where the original system (of which the hidden system is a clone) resides. In addition, due to this change, it is no longer required that the paging file is disabled and hibernation prevented when creating a hidden operating system.
* Many other improvements. (Windows, Mac OS X, and Linux)

<b> Bug fixes:</b>

* Many minor bug fixes and security improvements. (Windows, Mac OS X, and Linux)</i></ul>Aus der Erfahrung der letzten Releases würden wir Usern von Produktivsystemen jedoch dazu raten mit der Installation ein paar Tage zu warten, da bisher häufig schon nach kurzer Zeit jeweils eine a-Version als Bugfix nachgeschoben wurde.

Ist es eigentlich möglich auch eine dynamische Datei zu erstellen, die dann auch automatisch wieder verkleinert wird, wenn man was löscht?

Dynamic

Dynamic TrueCrypt container is a pre-allocated NTFS sparse file whose physical size (actual disk space used) grows as new data is added to it. Note that the physical size of the container (actual disk space that the container uses) will not decrease when files are deleted on the TrueCrypt volume. The physical size of the container can only increase up to the maximum value that is specified by the user during the volume creation process. After the maximum specified size is reached, the physical size of the container will remain constant.

Note that sparse files can only be created in the NTFS file system. If you are creating a container in the FAT file system, the option Dynamic will be disabled (“greyed out").

Note that the size of a dynamic (sparse-file-hosted) TrueCrypt volume reported by Windows and by TrueCrypt will always be equal to its maximum size (which you specify when creating the volume). To find out current physical size of the container (actual disk space it uses), right-click the container file (in a Windows Explorer window, not in TrueCrypt), then select Properties and see the Size on disk value.

WARNING: Performance of dynamic (sparse-file-hosted) TrueCrypt volumes is significantly worse than performance of regular volumes. Dynamic (sparse-file-hosted) TrueCrypt volumes are also less secure, because it is possible to tell which volume sectors are unused. Furthermore, if data is written to a dynamic volume when there is not enough free space in its host file system, the encrypted file system may get corrupted.

Ist es so kompliziert oder gar unmöglich so etwas zu integrieren?

habe noch nie einen sich selbst verkleinernden Container gesehen, auch VMWare muss ja extra shrinken. wenn nämliche die Dateien fragmentiert im Container liegen, ist es nicht mehr so leicht zu verkleinern. ich denke ein automatische Verkleinerung müsste immer gleich defragmentieren, was mehr nachteile als vorteile bringt.

Klingt logisch, aus deinem vorigen Post ließt man ja auch heraus, dass man lieber auf die Dynamik verzichten sollte.
Danke.

Wartet mit dem Installieren noch bis zum 12.11. Am 11. sollte die Version 6.1a nachgeschoben werden. War bisher immer so nach spätestens 7 Tagen.
