Computer hard disk private file encryption method and hidden skills (3)

In public places, some "big villains" can "black" out the private files in the hidden partition, making you shudder. In order to deal with this superb hacking technology, "Iron Man" has to strengthen security measures, using double encryption technology to hide important file encryption, to ensure that sensitive data is foolproof.

"TrueCrypt" is such an encryption software that can create an encryption container (corresponding to a file), and then virtualize the container into a disk partition with a password, which can be like operating a physical hard disk partition. That way, it is very convenient to place the files that need to be encrypted and then close the software. For others, the encrypted container itself is an unknown type of file that cannot be opened. Even if it is known as the "TrueCrypt" software encrypted file, the file cannot be opened without knowing the password, thereby achieving the effect of double encryption.

Step 1: First download and install the "TrueCrypt" encryption tool [Click to download
].

Click "Create Encrypted Volume" in the main window and follow the wizard prompts to select: create file-type encrypted volume, standard TrueCrypt encrypted volume, encrypt file location (set to a relatively hidden location), encryption algorithm Select AES, set the size of the encrypted volume (depending on the size of the file to be encrypted), set a complex outer encryption password greater than 20 characters (system recommended value, you can also set a simple password), and click the last step directly. The "Format" button is formatted (Figure 5).

Step 2: After the creation is complete, exit the wizard. In the "TrueCrypt" main window, find the created encrypted file by using the "Select File" button, then click "Load" and enter the correct password. After that.

Now, just open "My Computer" and you will see a new drive letter, double click to open, and then save the file to be encrypted (the operation is similar to the normal disk file operation method), after the file is encrypted Just quit the software directly (the operation method is similar when decrypting, loading an encrypted file is as simple as copying a file from the hard disk).

Tip: This software can also easily save important files to flash memory and mobile phones. The software also provides the production of portable encryption components, which can be directly added to flash memory and other devices. use.
