Suppose a Veracrypt container was mounted and dismounted later. Then CCleaner was run, Youtube was used to watch videos, websites are browsed, and so on for 3 hours. Then computer went to sleep (hibernate and pagefile disabled). What are the chances that the container can be decrypted because of whatever is left (master keys?) in the RAM or some where else??

Veracrypt version is below 1.24.

  • What OS is this running on? On Linux, it'll be using the kernel's dm-crypt which does wipe keys. – forest Jun 23 at 1:09

I have not personally verified this but according to Veracrypt Sourceforge:

  1. When the volume is dismounted, we securely wipe the encrypted master keys from memory.

  2. When Windows is shutdown or rebooted, we securely wipe the large memory region that was allocated at startup.

My interpretation is that recovering the keys after dismount would be unlikely.

  • Think that is only for 1.24 version... and also RAM encryption must be selected as an option in Veracrypt. – useraccount001 May 28 at 18:45
