In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability.

+<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
+Yes. There are generally no conflicts between TrueCrypt and VeraCrypt, thus they can be installed and used on the same machine. On Windows however, if they are both used to mount the same volume, two drives may appear when mounting it. This can be solved by
+ running the following command in an elevated command prompt (using Run as an administrator) before mounting any volume:

+<strong style="text-align:left">Can I convert my TrueCrypt volumes to VeraCrypt format?</strong></div>
+Yes. Starting from version 1.0f, VeraCrypt offers the possibility to convert TrueCrypt containers and non-system partitions to VeraCrypt format. This can achieved using the &quot;Change Volume Password&quot; or &quot;Set Header Key Derivation Algorithm&quot; actions. Just check
+ the &quot;TrueCrypt Mode&quot;, enter you TrueCrypt password and perform the operation. After that, you volume will have the VeraCrypt format.<br>
+Before doing the conversion, it is advised to backup the volume header using TrueCrypt. You can delete this backup safely once the conversion is done and after checking that the converted volume is mounted properly by VeraCrypt.</div>

+VeraCrypt adds enhanced security to the algorithms used for system and partitions encryption making it immune to new developments in brute-force attacks.<br>
+It also solves many vulnerabilities and security issues found in TrueCrypt.<br>
+As an example, when the system partition is encrypted, TrueCrypt uses PBKDF2-RIPEMD160 with 1000 iterations whereas in VeraCrypt we use
+<span style="text-decoration:underline">327661</span>. And for standard containers and other partitions, TrueCrypt uses at most 2000 iterations but VeraCrypt uses
+<span style="text-decoration:underline">655331 </span>for RIPEMD160 and <span style="text-decoration:underline">
+500000 </span>iterations for SHA-2 and Whirlpool.<br>
+This enhanced security adds some delay only to the opening of encrypted partitions without any performance impact to the application use phase. This is acceptable to the legitimate owner but it makes it much harder for an attacker to gain access to the encrypted
+ data.</div>

+<strong style="text-align:left">I forgot my password &ndash; is there any way ('backdoor') to recover the files from my VeraCrypt volume?</strong></div>
+<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
+We have not implemented any 'backdoor' in VeraCrypt (and will never implement any even if asked to do so by a government agency), because it would defeat the purpose of the software. VeraCrypt 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 VeraCrypt. The only way to recover your files is to try to &quot;crack&quot; the password or the key, but it could take thousands or
+ millions of years (depending on the length and quality of the password or keyfiles, on the software/hardware performance, algorithms, and other factors). Back in 2010, there was news about the

+FBI failing to decrypt a TrueCrypt volume after a year of trying</a>. While we can't verify if this is true or just a &quot;psy-op&quot; stunt, in VeraCrypt we have increased the security of the key derivation to a level where any brute-force of the password is virtually
+ impossible, provided that all security requirements are respected.</div>

+This can be caused by the TrueCrypt driver that clears BIOS memory before VeraCrypt is able to read it. In this case, uninstalling TrueCrypt solves the issue.<br>

+</div>
+<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
+Yes, VeraCrypt-encrypted volumes are like normal disks. You provide the correct password (and/or keyfile) and mount (open) the VeraCrypt volume. When you double click the icon of the video file, the operating system launches the application associated with
+ the file type &ndash; typically a media player. The media player then begins loading a small initial portion of the video file from the VeraCrypt-encrypted volume to RAM (memory) in order to play it. While the portion is being loaded, VeraCrypt is automatically
+ decrypting it (in RAM). 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 VeraCrypt-encrypted volume to
+ RAM (memory) and the process repeats.<br style="text-align:left">
+<br style="text-align:left">
+The same goes for video recording: Before a chunk of a video file is written to a VeraCrypt volume, VeraCrypt encrypts it in RAM and then writes it to the disk. This process is called on-the-fly encryption/decryption and it works for all file types (not only
+ for video files).</div>

+No. Those programs use TPM to protect against attacks that <em style="text-align:left">
+require</em> 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.
+<em style="text-align:left">However, if any of these conditions is met, it is actually impossible to secure the computer</em> (see below) and, therefore, you must stop using it (instead of relying on TPM).
+<br style="text-align:left">
+<br style="text-align:left">
+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 VeraCrypt 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).
+<br style="text-align:left">
+<br style="text-align:left">
+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 VeraCrypt 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). <br style="text-align:left">
+<br style="text-align:left">
+The only thing that TPM is almost guaranteed to provide is a false sense of security (even the name itself, &quot;Trusted Platform Module&quot;, is misleading and creates a false sense of security). As for real security, TPM is actually redundant (and implementing redundant
+ features is usually a way to create so-called bloatware). <br style="text-align:left">

+Windows built-in backup utility looks only for physical driver, that's why it doesn't display the VeraCrypt volume. Nevertheless, you can still backup on a VeraCrypt volume by using a trick: activate sharing on the VeraCrypt volume through Explorer interface
+ (of course, you have to put the correct permission to avoid unauthorized access) and then choose the option &quot;Remote shared folder&quot; (it is not remote of course but Windows needs a network path). There you can type the path of the shared drive (for example \\ServerName\sharename)

+VeraCrypt uses block ciphers (AES, Serpent, Twofish) for its encryption. Quantum attacks against these block ciphers are just a faster brute-force since the best know attack against these algorithms is exhaustive search (related keys attacks are irrelevant

+Since VeraCrypt always uses 256-bit random and independent keys, we are assured of a 128-bit security<br>
