TrueCrypt是涼快的

我的事務要求我保障某些文件安全。 多年來我使用了 被加密的不可思議的文件夾 (EMF)從加密那些文件和掩藏他們的個人計算機魔術從觀點的闖入者。 因為文件總在盤被加了密，仍然對應用，是充分地容易接近的我愛。 然而，當我升級了到景色64，新的EMF那麼完全地碰撞了我的系統它是不可啟動的甚而在安全模式下。 我兩次嘗試了它，兩次恢復了有某一困難，并且對EMF不抱希望。

我同時聽到了 TrueCrypt一個打開來源盤加密包裹為窗口和Linux。 它是自由的! 我必須承認那，在我下載了它之後，我需要某個時候在它附近得到我的頭腦。

這基本：

• 使用TrueCrypt應用您在您的系統大於您將需要拿著您的被加密的文件創造一個大「容器」文件。 它可以在所有讀寫盤，甚而記憶棍子和最初充滿隨機數據。
• 容器文件可以被複製，被移動，被刪除或者改名像其他文件。 它不是易碎的。 它可能有所有名字和任何文件擴展名。 您能有超過一。
• 以TrueCrypt應用，您 登上 那個容器文件作為一捲盤捲與它自己的驅動器字母。 您選擇信件。
• TrueCrypt應用在背景中跑并且處理TrueCrypt容量。
• 在TrueCrypt容量之內您在應該被加密的所有文件創造文件夾或者複製他們，并且創造或者複製。 TrueCrypt容量表現就像其他盤，即使它是真正地一個文件在您的硬盤或mem棍子。 每個文件在它裡面完全被加密，包括文件名字和甚而它的文件系統。
• 未使用的空間在TrueCrypt容器文件充滿不可能是卓越的從實際被加密的文件的隨機數據。
• 當您打開在一種應用的一個被加密的文件，例如文字處理機或圖形編輯時，文件正在進行中被解碼，以便應用看見它解碼了。
• 文件在盤從未被解碼，然而，除非應用保留臨時備用品和當然您在被加密的容量應該告訴您的應用也是保留那些。
• 被加密的數據備份是容易： 請卸下被加密的容量并且複製它的容器文件，仍然被加密，到備用媒介。
• If the backup medium is another disk, mem stick, DVD, or CD-ROM, you can actually mount that backup container file whenever you want without ever copying it back to the original hard disk.

That's the simple view of TrueCrypt. There is lots more. For example:

• Anyone examining your system or your disk can tell that you use TrueCrypt, and can probably even identify the container files.
• However, you can host a TrueCrypt volume within another truecrypt volume in a manner that makes the internal volume both hidden and undectable even if the outer volume is mounted and visible. Really cool. The TrueCrypt people call this "plausible deniability," and consider it quite important.
• Example: An adversary points a gun at you and demands to see your encrypted files. You can give them the password to the outer encrypted volume without ever revealing that an inner, hidden volume even exists. It's invisible. I don't actually see the need for a hidden volume in my business, but evidently some folks do.
• You can host a truecrypt volume on a public computer, or another person's computer, without installing any software on that computer, so your encrypted files are portable.
• You can tell TrueCrypt to mount certain TrueCrypt volumes automatically at bootup, though you will be required to enter a password to complete the mounting process.
• TrueCrypt allows you to use any of eight different encryption algorithms and three different hash algorithms, making decryption by an adversary even more difficult.

I love it, and in fact am using it for my encrypted files on my new computer. It works very well indeed, even on Vista 64. It is certainly no more trouble than EMF was, and backup is much simpler. It is far better than Windows Encrypted File System (EFS) because: (1) EFS files are always available when you log on, whereas TrueCrypt files require you to enter another password; and (2) EFS files cannot easily be backed up in their encrypted form. TrueCrypt is also much simpler than Windows BitLocker encryption, which requires you to partition your drive and poses some risk of losing the entire drive if something goes wrong.Popularity: 9%
