TrueCrypt是凉快的

我的事务要求我保障某些文件安全。 多年来我使用了 被加密的不可思议的文件夹 (EMF)从加密那些文件和掩藏他们的个人计算机魔术从观点的闯入者。 因为文件总在盘被加了密，仍然对应用，是充分地容易接近的我爱。 然而，当我升级了到景色64，新的EMF那么完全地碰撞了我的系统它是不可启动的甚而在安全模式下。 我两次尝试了它，两次恢复了有某一困难，并且对EMF不抱希望。

我同时听到了 TrueCrypt一个打开来源盘加密包裹为窗口和Linux。 它是自由的! 我必须承认那，在我下载了它之后，我需要某个时候在它附近得到我的头脑。

这基本：

• 使用TrueCrypt应用您在您的系统大于您将需要拿着您的被加密的文件创造一个大“容器”文件。 它可以在所有读写盘，甚而记忆棍子和最初充满随机数据。
• 容器文件可以被复制，被移动，被删除或者改名象其他文件。 它不是易碎的。 它可能有所有名字和任何文件扩展名。 您能有超过一。
• 以TrueCrypt应用，您 登上 那个容器文件作为一卷盘卷与它自己的驱动器字母。 您选择信件。
• TrueCrypt应用在背景中跑并且处理TrueCrypt容量。
• 在TrueCrypt容量之内您在应该被加密的所有文件创造文件夹或者复制他们，并且创造或者复制。 TrueCrypt容量表现就像其他盘，即使它是真正地一个文件在您的硬盘或mem棍子。 每个文件在它里面完全被加密，包括文件名字和甚而它的文件系统。
• 未使用的空间在TrueCrypt容器文件充满不可能是卓越的从实际被加密的文件的随机数据。
• 当您打开在一种应用的一个被加密的文件，例如文字处理机或图形编辑时，文件正在进行中被解码，以便应用看见它解码了。
• 文件在盘从未被解码，然而，除非应用保留临时备用品和当然您在被加密的容量应该告诉您的应用也是保留那些。
• 被加密的数据备份是容易： 请卸下被加密的容量并且复制它的容器文件，仍然被加密，到备用媒介。
• 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%
