Free open source on-the-fly encryption software. July 29, by admin. TrueCrypt does not allow decryption of data without knowing the correct password or key. We cannot recover your data because we do not know and cannot determine the password you chose or the key you generated using TrueCrypt. If you find this hard to believe, consider the fact that even the FBI was not able to decrypt a TrueCrypt volume after a year of trying. Yes, TrueCrypt-encrypted volumes are like normal disks. When you double click the icon of the video file, the operating system launches the application associated with the file type — typically a media player. The media player then begins loading a small initial portion of the video file from the TrueCrypt-encrypted volume to RAM memory in order to play it. The decrypted portion of the video stored in RAM is then played by the media player. While this portion is being played, the media player begins loading another small portion of the video file from the TrueCrypt-encrypted volume to RAM memory and the process repeats. The same goes for video recording: We will never create a commercial version of TrueCrypt, as we believe in open-source and free security software. If the source code were not available, reviewers would need to reverse-engineer the executable files. However, analyzing and understanding such reverse-engineered code is so difficult that it is practically impossible to do especially when the code is as large as the TrueCrypt code. A similar problem also affects cryptographic hardware for example, a self-encrypting storage device. In fact, the source code is constantly being reviewed by many independent researchers and users. We know this because many bugs and several security issues have been discovered by independent researchers including some well-known ones while reviewing the source code. In addition to reviewing the source code, independent researchers can compile the source code and compare the resulting executable files with the official ones. They may find some differences for example, timestamps or embedded digital signatures but they can analyze the differences and verify that they do not form malicious code. The entire file system within a TrueCrypt volume is encrypted including file names, folder names, and contents of every file. This applies to both types of TrueCrypt volumes — i. For more information, please see the chapter Parallelization in the documentation. Yes, since TrueCrypt uses pipelining and parallelization. For more information, please see the chapter Hardware Acceleration in the documentation. Yes, it is as of TrueCrypt 6. For more information, please see the section Hidden Operating System in the documentation. Yes, TrueCrypt volumes are independent of the operating system. Otherwise, data loss may occur. See the section Hidden Operating System in the documentation. See the chapter Plausible Deniability in the documentation. However, you need to make sure your operating system installer does not format the partition where your TrueCrypt volume resides. However, a running operating system can be updated security patches, service packs, etc. However, before upgrading, please read the release notes for all versions of TrueCrypt that have been released since your version was released. If there are any known issues or incompatibilities related to upgrading from your version to a newer one, they will be listed in the release notes. Note that this FAQ answer is also valid for users of a hidden operating system. Yes as of TrueCrypt 6. Then, when you start the computer, no texts will be displayed by the TrueCrypt boot loader not even when you enter the wrong password. It is, however, important to note that if the adversary can analyze the content of the hard drive, he can still find out that it contains the TrueCrypt boot loader. For more information, see the chapter System Favorite Volumes. See also the chapter Plausible Deniability. You can write data to the decoy system partition anytime without any risk that the hidden volume will get damaged because the decoy system is not installed within the same partition as the hidden system. For more information, see the section Hidden Operating System in the documentation. See the section Encryption Scheme chapter Technical Details in the documentation. Those programs use TPM to protect against attacks that require the attacker to have administrator privileges, or physical access to the computer, and the attacker needs you to use the computer after such an access. However, if any of these conditions is met, it is actually impossible to secure the computer see below and, therefore, you must stop using it instead of relying on TPM. If the attacker has administrator privileges, he can, for example, reset the TPM, capture the content of RAM containing master keys or content of files stored on mounted TrueCrypt volumes decrypted on the fly , which can then be sent to the attacker over the Internet or saved to an unencrypted local drive from which the attacker might be able to read it later, when he gains physical access to the computer. If the attacker can physically access the computer hardware and you use it after such an access , he can, for example, attach a malicious component to it such as a hardware keystroke logger that will capture the password, the content of RAM containing master keys or content of files stored on mounted TrueCrypt volumes decrypted on the fly , which can then be sent to the attacker over the Internet or saved to an unencrypted local drive from which the attacker might be able to read it later, when he gains physical access to the computer again. As for real security, TPM is actually redundant and implementing redundant features is usually a way to create so-called bloatware. For more information, please see the sections Physical Security and Malware in the documentation. File containers are normal files so you can work with them as with any normal files file containers can be, for example, moved, renamed, and deleted the same way as normal files. To solve this problem, defragment the file system in which the container is stored when the TrueCrypt volume is dismounted. See the chapter How to Back Up Securely in the documentation. The actual volume contents will be lost. However, the whole volume will remain encrypted. If you format a TrueCrypt-encrypted partition when the TrueCrypt volume that the partition hosts is not mounted, then the volume will be destroyed, and the partition will not be encrypted anymore it will be empty. Yes, the password change dialog works both for standard and hidden volumes. TrueCrypt first attempts to decrypt the standard volume header and if it fails, it attempts to decrypt the area within the volume where the hidden volume header may be stored if there is a hidden volume within. In case it is successful, the password change applies to the hidden volume. TrueCrypt complies with this requirement the TrueCrypt driver is digitally signed with the digital certificate of the TrueCrypt Foundation, which was issued by the certification authority GlobalSign. In encrypted data, one corrupted bit usually corrupts the whole ciphertext block in which it occurred. The ciphertext block size used by TrueCrypt is 16 bytes i. The mode of operation used by TrueCrypt ensures that if data corruption occurs within a block, the remaining blocks are not affected. File system within a TrueCrypt volume may become corrupted in the same way as any normal unencrypted file system. When that happens, you can use filesystem repair tools supplied with your operating system to fix it. TrueCrypt provides an easy way to use this tool on a TrueCrypt volume: Similarly, you can reset a pre-boot authentication password. Provided that you comply with the terms and conditions of the TrueCrypt License , you can install and run TrueCrypt free of charge on an arbitrary number of your computers. Yes, but you will need to remove the drive letter assigned to the device. Yes, the documentation is contained in the file TrueCrypt User Guide. Just run the self-extracting installation package and then select Extract instead of Install on the second page of the TrueCrypt Setup wizard. If you believe that an adversary will be able to decrypt the volume for example that he will make you reveal the password , then the answer is yes. Otherwise, it is not necessary, because the volume is entirely encrypted. Please see the section Encryption Scheme chapter Technical Details in the documentation. Truecrypt Free open source on-the-fly encryption software. Can I directly play a video. Will TrueCrypt be open-source and free forever? Why is TrueCrypt open-source? What are the advantages? TrueCrypt is open-source, but has anybody actually reviewed the source code? Can they also verify that the official executable files were built from the published source code and contain no additional code? You have two options: Encrypt the entire USB flash drive. Windows does not support multiple partitions on USB flash drives. Does TrueCrypt also encrypt file names and folder names? Does TrueCrypt use parallelization? Does TrueCrypt support hardware-accelerated encryption? Is it possible to boot Windows installed in a hidden TrueCrypt volume? Will I be able to mount my TrueCrypt volume container on any computer? What is a hidden operating system? What is plausible deniability? Can I upgrade from an older version of TrueCrypt to the latest version without any problems? I use pre-boot authentication. Can I prevent a person adversary that is watching me start my computer from knowing that I use TrueCrypt? To do so, follow these steps: Mount the volume to the drive letter to which you want it to be mounted every time. The System Favorites Organizer window should appear now. Can a volume be automatically mounted whenever I log on to Windows? The Favorites Organizer window should appear now. The Preferences window should appear now. Can a volume be automatically mounted whenever its host device gets connected to the computer? Can my pre-boot authentication password be cached so that I can use it mount non-system volumes during the session? I live in a country that violates basic human rights of its people. You must perform each of the following steps from within BartPE. If the adversary can intercept data you send or receive over the Internet and you need to prevent the adversary from knowing you downloaded TrueCrypt, consider downloading it via I2P , Tor , or a similar anonymizing network. Verify the digital signatures of the downloaded file see this section of the documentation for more information. Run the downloaded file, and select Extract instead of Install on the second page of the TrueCrypt Setup wizard. Extract the contents to the RAM disk. Run the file TrueCrypt. Yes, TrueCrypt supports all keyboard layouts. Can I save data to the decoy system partition without risking damage to the hidden system partition? Does TrueCrypt save my password to a disk? How does TrueCrypt verify that the correct password was entered? Yes, but the following conditions must be met: If you want to encrypt an entire system drive which may contain multiple partitions or a system partition in other words, if you want to encrypt a drive or partition where Windows is installed , you can do so provided that you use TrueCrypt 5. If you want to encrypt a non-system partition in place, you can do so provided that it contains an NTFS filesystem, that you use TrueCrypt 6. Some encryption programs use TPM to prevent attacks. Will TrueCrypt use it too? Do I have to dismount TrueCrypt volumes before shutting down or restarting Windows? Which type of TrueCrypt volume is better — partition or file container? What will happen if I format a TrueCrypt partition? Is it possible to change the password for a hidden volume? Can I use tools like chkdsk , Disk Defragmenter, etc. Does TrueCrypt support bit versions of Windows? Yes, TrueCrypt volumes are fully cross-platform. Is there a list of all operating systems that TrueCrypt supports? Is it possible to install an application to a TrueCrypt volume and run it from there? What will happen when a part of a TrueCrypt volume becomes corrupted? What do I do when the encrypted filesystem on my TrueCrypt volume is corrupted? Is there a way for an administrator to reset a volume password or pre-boot authentication password when a user forgets it or loses a keyfile? Can our commercial company use TrueCrypt free of charge? We share a volume over a network. Is there a way to have the network share automatically restored when the system is restarted? It is possible to access a single TrueCrypt volume simultaneously from multiple operating systems for example, a volume shared over a network? Can a user access his or her TrueCrypt volume via a network? When I double click this drive letter, Windows asks if I want to format the drive. Is there a way to hide or free this drive letter? Yes, to free the drive letter follow these steps: If Windows prompts you to confirm the action, click Yes. Is there a way to prevent that? How do I permanently decrypt a volume? Is the online documentation available for download as a single file? How does TrueCrypt know which encryption algorithm my TrueCrypt volume has been encrypted with?
