Nowadays we use computer to manage and store more and more commercial, critical or intimate data, we store the data on local hard disk, usb flash drive, external hard drive, CDs/DVDs, online hard drive, etc. If you lost your computer or removable storage drive, you may feel it is the end of the world! Today I’ll bring you a free encryption software, with the help of it, anyone else wont be able to steal your data actually, if they do not have the password, they can do nothing with your document!
TrueCrypt is a free disk encryption application, it’s lightweight, stable, easy to use, open source and reliable. I’ve been using it for over 3 years without any problems, now it’s one of my must have software! TrueCrypt gives you the ability to encrypt entire system partition / non-system partition, and it allows you create an encrypted file container, I prefer the later option, it allows you mount a single file as a virtual drive, I’ll tell you how to create and use a virtual drive in the following steps.
First press the “Create Volume” button, then select “Create an encrypted file container” and press Next, Next, then choose a file to store the virtual drive, then choose the encryption algorithm( AES, Serpent, Twofish, AES-Twofish, AES-Twofish-Serpent, Serpent-AES, Serpent-Twofish-AES, Twofish-Serpent ), and one hash algorithm( RIPEMD-160, SHA-512, Whirlpool ), then press next and specify the size of virtual disk, then enter your password in the next step, then choose the filesystem( FAT / NTFS ) and press Format, close the wizard dialog when the format is finished and return to the main window.
Now you are ready to use your virtual disk, just select the file you’ve just created, and choose a drive letter from the list above, then press Mount, then enter your password, a new virtual partition will be available now, you can format it, create / copy / move /delete any file / folder in it, the encryption / decryption is transparent to you, when a file is written to or read from the virtual drive, TrueCrypt will encrypt / decrypt it in the background automatically.
After you’ve dismounted the virtual disk, anybody who has no password won’t be able to mount it and thus can’t explore the content inside it. However, you should keep your system clean, if your password is stolen by a keylogger / spyware / rootkit, nobody could help you.
