Securing computer data through encryption software has become a clear necessity for many businesses and individuals carrying sensitive information on their laptops or USB flash drives.確保計算機數據加密軟件，已成為一個清晰的必要性，為許多企業和個人進行敏感的資料，說明其筆記本電腦或usb閃盤。 Unfortunately, many people do not encrypt their data because it is not easy to implement in Windows and the learning curve is too high.不幸的是，很多人不加密的數據，因為它是執行上並不容易，在窗戶和學習曲線實在太高。 However, thanks to open source initiatives, you can use a completely free program called不過，由於開放源碼的舉措，你可以使用完全免費的程序，稱為 TrueCrypt truecrypt to encrypt an entire hard drive, a USB flash drive, or even create a virtual encrypted disk in a file that acts as a real disk.加密整個硬盤，一個usb閃存驅動器，或什至創造一個虛擬的加密磁盤，在一個文件說，作為一個真正的磁盤。
The cool thing about TrueCrypt is that you can create a virtual disk on your computer that will look and feel just like a normal disk on your computer.乘涼的一件事truecrypt是，你可以創建一個虛擬磁盤上你的電腦，將外觀和感覺就像一個正常的磁盤上你的電腦。 The “drive” will actually be a file stored on your computer, but it is completely encrypted and secure, so that when you turn off your computer, the data CANNOT be recovered unless you know the correct password. "驅動器"其實是一個文件存儲在您的計算機上，但它是完全加密和保護，所以，當你關掉你的電腦，數據不能收回的，除非你知道正確的密碼。 Of course, this means that if you forget your password, your data will be lost forever, so be very careful not to lose the password!當然，這意味著，如果你忘了密碼，你的數據將永遠喪失，所以要很小心，不要輸密碼！
Just like any other drive, you can install programs on the drive, play videos and songs directly from the drive, etc. Basically, when you access any file on a TrueCrypt drive, it is unencrypted and loaded into RAM.就像任何其他驅動器，你可以安裝程序，對硬盤，玩視頻和歌曲直接從驅動器等，基本上，當您進入任何文件就truecrypt徑，它是加密的，並裝入內存。 Data is never written to the hard disk.數據是永遠不會寫入硬盤。 The reason for this is because if the power were to suddenly go out and your computer turned off, the data in memory would be lost, but the data on the hard drive would still be accessible.這一現象的原因是因為，如果權力的人突然走出去和你的電腦關機，數據存儲器將會消失，但數據對硬盤仍然可以訪問。
TrueCrypt even encrypts the file names and the folder names on the volume. truecrypt甚至加密，文件名稱和文件夾名字，音量。 The nice thing about TrueCrypt is that you can also create one of these virtual volumes on a USB stick and run the program off the stick, so that you can carry your encrypted data around with you safely.尼斯的一件事truecrypt是，你也可以創造之一，這些虛擬卷上的usb堅持和運行程序小康硬性措施，使你能夠將你的加密數據周圍與你平安。 If you lose the stick, not a problem because it cannot be accessed unless the password is known!如果你失去了堅持，而不是一個大問題，因為它無法進入，除非密碼是眾所周知的！
TrueCrypt supports Windows Vista and Windows XP x64. truecrypt支持windows vista和windows xp的64位服務器。 It also runs on Linux and you can open a TrueCrypt volume on any of these platforms.它也可運行於linux ，你也可以打開一個truecrypt量對上述任何一個平台。
Once installed, click on Create Volume to get started.一旦安裝後，點擊創造貨量準備開始工作。 Choose Create a Standard TruCrypt Volume .選擇創建一個標準trucrypt量 。
Next choose a location for the file.未來選擇一個地點作為檔案。 Click Select File , browse to where you want the file stored and type in a name for the file.單擊選擇文件 ，瀏覽到你想儲存的檔案，並輸入文件名。
Next choose the encryption that you want.明年選擇加密您想要的。 The default option is the lowest encryption method, AES.默認的選項是最低的加密方法，原子發射光譜。 The last option in the drop-down is the highest encryption, but only choose that if you have LOTS of processing power and RAM.最後一個選項，在下拉，這是最高的加密，但只能選擇，如果你有大量的處理能力和內存。 Remember, each time something is read from the virtual disk, it has to be decrypted and it will take more time to decrypt if the encryption is stronger.請記住，每一次的東西是從虛擬磁盤，它必須被解密，而且需要更多的時間來解密，如果加密更強。
Next choose the size for your virtual drive. 明年選擇大小為你的虛擬硬盤。 Click Next and now type in a strong password. 單擊下一步，現在鍵入強密碼。 It is essential you type in a long and complex password so that it cannot be easily cracked. 它是必不可少的，你鍵入一個漫長而複雜的密碼，以便使它不能輕易告破。 The program suggests it be a minimum of 20 characters, but that was definitely too long for me! 該計劃表明，它是一個最起碼的20個字，但肯定是太長了我！
On the next scree, you want to move your mouse inside the TrueCrypt screen really fast in order to generate a really random header and master key. 就下一步卵石，你想搬到你的鼠標內truecrypt屏幕真快，以產生一個真正的隨機頭和萬能鑰匙。 Choose the format of the drive and click Format . 選擇格式的驅動器，並單擊格式。
Finally, click Exit to get back to the main screen. 最後，點擊退出回到主畫面。 Choose a letter from the drive list and click Select File to pick the volume that you will be mounting. 選擇一個信從驅動器列表中單擊選擇file摘量，你會的呼聲日益高漲。
Now click the Mount button at the bottom to “connect” or mount the file to the selected drive letter. You’ll be asked to type in the password that you entered while creating the virtual volume.現在按一下按鈕，安裝在底部的"連接" ，或登上該文件到指定盤符，你將被要求輸入密碼，你進入的同時，創造虛擬卷。 Click OK and you should see the list updated:單擊確定，你應該看到的最新名單：

Now you can use the drive normally.現在你可以使用驅動正常。 When you restart or turn off your computer, the drive is dismounted and the drive is inaccessible.當你重新啟動或關掉你的電腦，驅動器是拆卸和幹勁，是行不通的。 When Windows starts, you will have to re-mount the drive with the correct password.當windows打響後，你將不得不重新登上駕駛正確的密碼。 This is a good way to kind of password protect a folder in Windows XP or Windows Vista.這是一個很好的方法種密碼保護的文件夾，在windows xp或windows vista的。 You’ll only be asked for the password whenever the computer is started up.你只能要求密碼時，電腦啟動了。
