Added container (encrypted volume) repair function

Open fzxx opened this issue 2 years ago • 3 comments

Some users have corrupted disks, corrupted encrypted volumes, and they do not have the expertise to repair them;

Desired behavior

So it is recommended to add repair functions (similar to Windows Disk Check, Cryptomator Vault Health Check);

Additional information

It is recommended to incorporate into the Encrypted Volumes tool.

Your Environment

Windows 11 x64

@idrassi If this is difficult, you can add the backup volume header and backup volume partition table first. to achieve the purpose of preliminary repair.

I might not be understanding this, but all Veracrypt headers are encrypted to prevent an adversary to figure out from the data itself that it is a Veracrypt volume. Cryptomator does not hide this though.

Recreating the header would require everything listed at [https://veracrypt.fr/en/VeraCrypt%20Volume%20Format%20Specification.html](Volume Format Specification) which would be impossible if the user doesn't manually remember every single key, every hash, and others.

No matter how user-friendly the repair wizard might be, we have to rely on the user for info that they might not remember like the EXACT hash and volume size as examples.

It should be the onus of the user to backup the header.

我可能不理解这一点,但是,所有Veracrypt头进行加密,以防止敌对图出的数据本身,这是一个Veracrypt量。 Cryptomator不隐藏这一点,虽然。

重新标题,将需要的一切所列,在https://veracrypt.fr/en/VeraCrypt%20Volume%20Format%20Specification.html,这将是不可能的,如果用户没有手工记得每一个关键,每散,和其他人。

无论如何用户友好的维修导可能是,我们必须依靠用户的信息,他们可能不记得就像的精确散和体积的大小作为例子。

它应该责任的用户的备份标题。

Repair function: equivalent to a small encrypted volume, file header + backup information @idrassi
