TrueCrypt v4.0 - Datenverschlüsselung
für Windows 2000 / XP / 2003, es ist aber auch eine Linux-Version verfügbar

TrueCrypt ist ein kostenloses Programm zur Verschlüsselung von Dateien, Partitionen, USB-Sticks uvm. ab W2K. Das Programm bindet Containerdateien in das System ein, oder verschlüsselt ganze Festplattenbereiche und agiert mittels verschiedener Verfahren mit 128-, 256-, oder 448-Bit-Keys "on the fly".
Die angelegten "Virtual Volumes" werden nach Passworteingabe gemountet und lassen sich wie normale Partitionen oder Datenträger verwenden und über den Explorer aufrufen. (Textquelle WinFuture)



Haupt-Features:
- It can create a virtual encrypted disk within a file and mount it as a real disk.
- It can encrypt an entire hard disk partition or a device, such as USB memory stick, floppy disk, etc.
- Provides two levels of plausible deniability, in case an adversary forces you to reveal the password:
   1) Hidden volume.
   2) No TrueCrypt volume can be identified (TrueCrypt volumes cannot be distinguished from random data).
-Encryption algorithms: AES-256, Blowfish (448-bit key), CAST5, Serpent (256-bit key), Triple DES, and Twofish (256-bit key). Supports cascading (e.g., AES-Twofish-Serpent).
- Based on Encryption for the Masses (E4M) 2.02a, which was conceived in 1997.

Die Kaskade von Chiffren im Outer-CBC-Mode ist immer mindestens so stark wie die stärkste aller beteiligten Chiffren, wenn die Schlüssellängen nicht fallend sind.
Umverschlüsseln kann man AFAIK nicht, man kann nur den Key ändern.

TrueCrypt v4.2a - Datenverschlüsselung (Open-Source)

Zitat

4.2a
July 3, 2006

Bug fixes:

Writing to a TrueCrypt volume under Linux no longer causes the system to stop responding under certain conditions.

Occasional application errors no longer occur when selecting a file (Windows XP SP2 issue).

Fixed bug that caused installation of the TrueCrypt driver to fail under certain configurations of 64-bit Windows.

TrueCrypt volumes mounted in a remote session under Windows 2000 can now be accessed.

TrueCrypt Volume Creation Wizard no longer blocks hot keys of certain applications. (Windows)

Other minor bug fixes (Windows and Linux)


Improvements:

It will not be required to reinstall the TrueCrypt kernel module after every minor Linux kernel update.

Support for latest Linux kernel (2.6.17)

Other minor improvements (Windows and Linux)

Security improvements:

The Linux version of TrueCrypt now uses the TrueCrypt Random Number Generator (ported from the Windows version of TrueCrypt) instead of using only the Linux built-in random number generator. (This change was necessary due to a flaw in the Linux built-in random number generator: Data from the mouse and keyboard, which are the most important sources of random data, are not read by the Linux built-in random number generator when the user has only a USB mouse/keyboard.)
Note: The Linux version of TrueCrypt still uses the Linux built-in random number generator. However, it is now merely one of the data sources used by the TrueCrypt random number generator.

Interactive mount mode, which allows the user to avoid passing sensitive parameters via command line. (Linux)

TrueCrypt volume is unmapped if mounting it to a directory fails. (Linux)

When the ‘Never Save History’ option is enabled, TrueCrypt sets its “current directory” to the user’s home directory (in traveller mode, to the directory from which TrueCrypt was launched) after a container or keyfile is selected via the Windows file selector. Therefore, the Windows file selector will not “remember” the path of the last selected container or keyfile. (Windows)


Miscellaneous:

Released under the TrueCrypt Collective License Version 1.0

Changelog:

Zitat

New features:

*Ability to encrypt a system partition/drive (i.e. a partition/drive where Windows is installed) with pre-boot authentication (anyone who wants to gain access and use the system, read and write files, etc., needs to enter the correct password each time before the system starts). For more information, see the chapter System Encryption in the documentation. (Windows Vista/XP/2003)

* Pipelined operations increasing read/write speed by up to 100% (Windows)

* Mac OS X version

* Graphical user interface for the Linux version of TrueCrypt

* XTS mode of operation, which was designed by Phillip Rogaway in 2003 and which was recently approved as the IEEE 1619 standard for cryptographic protection of data on block-oriented storage devices. XTS is faster and more secure than LRW mode (for more information on XTS mode, see the section Modes of Operation in the documentation).

Note: New volumes created by this version of TrueCrypt can be encrypted only in XTS mode. However, volumes created by previous versions of TrueCrypt can still be mounted using this version of TrueCrypt.

* SHA-512 hash algorithm (replacing SHA-1, which is no longer available when creating new volumes).

Note: To re-encrypt the header of an existing volume with a header key derived using HMAC-SHA-512 (PRF), select 'Volumes' > 'Set Header Key Derivation Algorithm'.

Improvements, bug fixes, and security enhancements:

* The Linux version of TrueCrypt has been redesigned so that it will no longer be affected by changes to the Linux kernel (kernel upgrades/updates).

* Many other minor improvements, bug fixes, and security enhancements. (Windows and Linux)

If you are using an older version of TrueCrypt, it is strongly recommended that you upgrade to this version.

Changelog:

Zitat

Improvements:

* The memory requirements for the TrueCrypt Boot Loader have been reduced by 18 KB (eighteen kilobytes). As a result of this improvement, the following problem will no longer occur on most of the affected computers: The memory requirements of the TrueCrypt Boot Loader 5.0 prevented users of some computers from encrypting system partitions/drives (when performing the system encryption pretest, the TrueCrypt Boot Loader displayed the following error message: Insufficient memory for encryption).


Bug fixes:

*On computers equipped with certain brands of audio cards, when performing the system encryption pretest or when the system partition/drive is encrypted, the sound card drivers failed to load. This will no longer occur. (Windows Vista/XP/2003)

*It is possible to access mounted TrueCrypt volumes over a network. (Windows)

*TrueCrypt Rescue Disks created by the previous version could not be booted on some computers. This will no longer occur. (Windows Vista/XP/2003)

Note: If your TrueCrypt Rescue Disk created by TrueCrypt 5.0 cannot be booted on your computer, please upgrade to this version of TrueCrypt and then create a new TrueCrypt Rescue Disk (select 'System' > 'Create Rescue Disk').

* Many other minor bug fixes. (Windows, Mac OS X, and Linux)

TrueCrypt 5.1

Homepage: http://www.truecrypt.org

Zum Download: http://www.truecrypt.org/downloads.php

Changelog:

Zitat

New features:

* Support for hibernation on computers where the system partition is encrypted (previous versions of TrueCrypt prevented the system from hibernating when the system partition was encrypted). (Windows Vista/XP/2008/2003)

* Ability to mount a partition that is within the key scope of system encryption without pre-boot authentication (for example, a partition located on the encrypted system drive of another operating system that is not running). (Windows Vista/XP/2008/2003)

Note: This can be useful e.g. when there is a need to back up or repair an operating system encrypted by TrueCrypt (from within another operating system).

* Command line options for creating new volumes. (Linux and Mac OS X)


Improvements:

* Increased speed of AES encryption/decryption (depending on the hardware platform, by 30-90%). (Windows)

* Faster booting when the system partition is encrypted. (Windows Vista/XP/2008/2003)

* When the system partition/drive is encrypted, the TrueCrypt Boot Loader is now stored in a compressed form and is, therefore, smaller. If a non-cascade encryption algorithm is used (i.e., AES, Serpent, or Twofish), the TrueCrypt Boot Loader is now small enough so that a backup of the TrueCrypt Boot Loader can be (and is) stored in first drive cylinder. Whenever the TrueCrypt Boot Loader is damaged, its backup copy is run automatically instead.

As a result of this improvement, the following problem will no longer occur: Certain inappropriately designed activation software (used for activation of some third-party software) writes data to the first drive cylinder, thus damaging the TrueCrypt Boot Loader. The affected users had to use the TrueCrypt Rescue Disk to repair the TrueCrypt Boot Loader. This will no longer be necessary after upgrading to this version of TrueCrypt (provided that the system partition/drive is encrypted using a non-cascade encryption algorithm, i.e., AES, Serpent, or Twofish).

Note: If your system partition/drive is currently encrypted using a non-cascade encryption algorithm (i.e., AES, Serpent, or Twofish), a backup copy of the TrueCrypt Boot Loader will be automatically stored in the first drive cylinder when you upgrade to this version of TrueCrypt.

* The minimum memory requirements for the TrueCrypt Boot Loader have been reduced from 42 KB to 27 KB (twenty-seven kilobytes). This allows users to encrypt system partitions/drives on computers where the BIOS reserves a large amount of memory. (Windows Vista/XP/2008/2003)

* Many other minor improvements. (Windows, Mac OS X, and Linux)


Resolved incompatibilities:

* On some computers, when performing the system encryption pretest, Windows failed to display the log-on screen. This will no longer occur. (Windows Vista/XP/2008/2003)


Bug fixes:

* On some systems, drive letters were not correctly assigned to newly mounted non-system volumes. This will no longer occur. (Windows)

* Many other minor bug fixes. (Windows, Mac OS X, and Linux)

TrueCrypt 5.1a

Homepage: http://www.truecrypt.org
Downloads: http://www.truecrypt.org/downloads.php

Changelog:

Zitat

Improvements:

* Faster booting when the system partition/drive is encrypted (typically by 10%). (Windows Vista/XP/2008/2003)
* Other minor improvements. (Windows, Mac OS X, and Linux)

Resolved incompatibilities:

* On computers with certain hardware configurations, resuming from hibernation failed when the system partition was encrypted. Note: If you encountered this problem, the content of RAM may have been saved unencrypted to the hibernation file. You can erase such data, for example, by decrypting the system partition/drive (select System > Permanently Decrypt System Partition/Drive) and then encrypting it again. (Windows Vista/XP/2008/2003)

Remark: As Microsoft does not provide any API for handling hibernation, all non-Microsoft developers of disk encryption software are forced to modify undocumented components of Windows in order to allow users to encrypt hibernation files. Therefore, no disk encryption software (except for Microsoft's BitLocker) can guarantee that hibernation files will always be encrypted. At anytime, Microsoft can arbitrarily modify components of Windows (using the Auto Update feature of Windows) that are not publicly documented or accessible via a public API. Any such change, or the use of an untypical or custom storage device driver, may cause any non-Microsoft disk encryption software to fail to encrypt the hibernation file. We plan to file a complaint with Microsoft (and if rejected, with the European Commission) about this issue, also due to the fact that Microsoft's disk encryption software, BitLocker, is not disadvantaged by this.

* Workaround for a bug in the BIOS of some Apple computers that prevented users from entering pre-boot authentication passwords and controlling the TrueCrypt Boot Loader. (Windows Vista/XP/2008/2003)

Bug fixes:

* When the system partition/drive is decrypted under Windows, the original partition table will not be restored. Note: This issue affected users who repartitioned an encrypted system drive and then decrypted it under Windows. (Windows Vista/XP/2008/2003)

* Other minor bug fixes. (Windows, Mac OS X, and Linux)

TrueCrypt v6.0 - Datenverschlüsselung
für Windows 2000 / XP / 2003 / Vista, es ist aber auch eine Linux-Version verfügbar

We are pleased to announce that TrueCrypt 6.0 has been released.
This version introduces parallelized encryption and decryption on multi-core processors (or multi-processor systems). Increase in encryption/decryption speed is directly proportional to the number of cores and/or processors. For example, on a quad-core processor, encryption and decryption is four times faster than on a single-core processor with equivalent specifications [view benchmark results].
This version also introduces the ability to create and run an encrypted hidden operating system whose existence is impossible to prove (provided that certain guidelines are followed), the ability to encrypt an entire system drive even if it contains extended partitions, a new volume format that increases reliability, performance and expandability, and more.

Einen umfangreichen Changelog mit den Neuerungen gibt es hier.
