<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
<meta name="description" content="VeraCrypt is free open-source disk encryption software for Windows, Mac OS X and Linux. In case an attacker forces you to reveal the password, VeraCrypt provides plausible deniability. In contrast to file encryption, data encryption performed by VeraCrypt is real-time (on-the-fly), automatic, transparent, needs very little memory, and does not involve temporary unencrypted files."/>

When running, the hidden operating system appears to be installed on the same partition as the original operating system (the decoy system). However, in reality, it is installed within the partition behind it (in a hidden volume). All read/write operations
are transparently redirected from the system partition to the hidden volume. Neither the operating system nor applications will know that data written to and read from the system partition is actually written to and read from the partition behind it (from/to
a hidden volume). Any such data is encrypted and decrypted on the fly as usual (with an encryption key different from the one that is used for the decoy operating system).</div>

Note that there will also be a third password &mdash; the one for the <a href="Hidden%20Volume.html" style="text-align:left; color:#0080c0; text-decoration:none.html">
<strong style="text-align:left">outer volume</strong></a>. It is not a pre-boot authentication password, but a regular VeraCrypt volume password. It can be safely disclosed to anyone forcing you to reveal the password for the encrypted partition where the hidden
volume (containing the hidden operating system) resides. Thus, the existence of the hidden volume (and of the hidden operating system) will remain secret. If you are not sure you understand how this is possible, or what an outer volume is, please read the

To summarize, there will be three passwords in total. Two of them can be revealed to an attacker (for the decoy system and for the outer volume). The third password, for the hidden system, must remain secret.</div>

Process of Creation of Hidden Operating System</h4>
<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
To start the process of creation of a hidden operating system, select <em style="text-align:left">
System</em> &gt; <em style="text-align:left">Create Hidden Operating System</em> and then follow the instructions in the wizard.</div>
<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
Initially, the wizard verifies that there is a suitable partition for a hidden operating system on the system drive. Note that before you can create a hidden operating system, you need to create a partition for it on the system drive. It must be the first partition
behind the system partition and it must be at least 5% larger than the system partition (the system partition is the one where the currently running operating system is installed). However, if the outer volume (not to be confused with the system partition)
is formatted as NTFS, the partition for the hidden operating system must be at least 110% (2.1 times) larger than the system partition (the reason is that the NTFS file system always stores internal data exactly in the middle of the volume and, therefore,
the hidden volume, which is to contain a clone of the system partition, can reside only in the second half of the partition).</div>
<div style="text-align:left; margin-top:19px; margin-bottom:19px; padding-top:0px; padding-bottom:0px">
In the next steps, the wizard will create two VeraCrypt volumes (<a href="Hidden%20Volume.html" style="text-align:left; color:#0080c0; text-decoration:none.html">outer and hidden</a>) within the first partition behind the
system partition. The <a href="Hidden%20Volume.html" style="text-align:left; color:#0080c0; text-decoration:none.html">
hidden volume</a> will contain the hidden operating system. The size of the hidden volume is always the same as the size of the system partition. The reason is that the hidden volume will need to contain a clone of the content of the system partition (see below).
Note that the clone will be encrypted using a different encryption key than the original. Before you start copying some sensitive-looking files to the outer volume, the wizard tells you the maximum recommended size of space that the files should occupy, so
that there is enough free space on the outer volume for the hidden volume.</div>
