<title>VeraCrypt - Free Open source disk encryption with strong security for the Paranoid</title>
<metaname="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."/>

<h3>Cache Password in Driver Memory</h3>
<p>This option can be set in the password entry dialog so that it will apply only to that particular mount attempt. It can also be set as default in the Preferences. For more information, please see the section
<em>Volume Mounted as Removable Medium</em></a>.</p>
<h4>Use backup header embedded in volume if available</h4>
<p>All volumes created by VeraCrypt contain an embedded backup header (located at the end of the volume). If you check this option, VeraCrypt will attempt to mount the volume using the embedded backup header. Note that if the volume header is damaged, you do
not have to use this option. Instead, you can repair the header by selecting <em>
Tools</em>><em>Restore Volume Header</em>.</p>
<h4>Mount partition using system encryption without pre-boot authentication</h4>
<p>Check this option, if you need to mount a partition that is within the key scope of system encryption without pre-boot authentication. For example, if you need to mount a partition located on the encrypted system drive of another operating system that is
not running. This can be useful e.g. when you need to back up or repair an operating system encrypted by VeraCrypt (from within another operating system). Note that this option can be enabled also when using the ‘<em>Auto-Mount Devices</em>’ or
‘<em>Auto-Mount All Device-Hosted Volumes</em>’ functions.</p>
