TrueCrypt 中的所有檔案都會損壞嗎?

如果我在 TrueCrypt 容器/磁碟區中有 15 個文件,然後假設加密磁碟區是否在容器文件中的某個位置損壞。這是否意味著該磁碟區無法再解密以保留可能安全的檔案?會變得無法使用嗎?

答案1

不會。假設您的損壞範圍有限,您應該能夠恢復大部分資料。來自TrueCrypt 常見問題解答:

What will happen when a part of a TrueCrypt volume becomes corrupted?

In encrypted data, one corrupted bit usually corrupts the whole
ciphertext block in which it occurred. The ciphertext block size used
by TrueCrypt is 16 bytes (i.e., 128 bits). The mode of operation used
by TrueCrypt ensures that if data corruption occurs within a block,
the remaining blocks are not affected. See also the question 'What do
I do when the encrypted filesystem on my TrueCrypt volume is
corrupted?


What do I do when the encrypted filesystem on my TrueCrypt volume is corrupted?

File system within a TrueCrypt volume may become corrupted in the same
way as any normal unencrypted file system. When that happens, you can
use filesystem repair tools supplied with your operating system to fix
it. In Windows, it is the 'chkdsk' tool. TrueCrypt provides an easy
way to use this tool on a TrueCrypt volume: Right-click the mounted
volume in the main TrueCrypt window (in the drive list) and from the
context menu select 'Repair Filesystem'.
