First download the TrueCrypt, copy to the U disk, and then run TrueCrypt.exe. 1. Create a file encryption volume 2, choose a U disk, name a file name, such as "virtual disk _ do not delete" 3, encryption algorithm, select the default AES can 4, enter the total size of the disk image file you need to create. 5, fill in the encryption volume password, you need to use this password to open the virtual disk. 6, the format of the encryption volume 7

mount the volume, here choose the second way I will mount the volume-only on Linux, click the Next button and the interface shown in 2.19 is displayed.Figure 2.19 Volume Format(15) Now to format the previously created volume, click the Format button and the interface shown in 2.20 will be displayed.Figure 2.20 Formatting Process(16) This interface displays information such as the progress, speed, and time of the formatting. When the process finishes

1. FSlint-FSlint can effectively help the system avoid the troubles of deleting duplicate files, empty folders, and some other types of junk files. 2. TestDisk-it is a file recovery and Repair Tool. Ext4 is not currently supported. You can use it to restore important data and files on your disk. 3. TrueCrypt-it is a free and open-source encryption software that supports Windows Vista, 7/XP, Mac OS X, Linux,

creating a new volume is again similar to that of TrueCrypt: A wizard is provided to guide you through the entire process and related options are provided in each step. FreeOTFE has a range of more options that involve the volume's random data string (salt) and hash length, password, key, and disk sector systems, but for most users, use the default option. Some options are mainly provided for backward compatibility, such as the obsolete MD2 and MD4 h

Linux, there are several tools to choose from. In this tutorial, I intend to introduce one of these: Ecryptfs, a user-space File system encryption tool. A summary of the encryption tools available on Linux is provided below for your reference. File system level Encryption EncFS: One of the easiest ways to try encryption. ENCFS works on a fuse-based pseudo file system, so you just need to create an encryp

ENCFS works on a fuse-based pseudo-file system, so you just need to create an encrypted folder and mount it to a folder to work.Ecryptfs: A POSIX-compatible encrypting File System, ECRYPTFS works the same way as ENCFS, so you have to mount it.Disk-level encryptionLoop-aes: The oldest method of disk encryption.

. As we all know,linux system everything is a file, so each process has its file descriptor, The Nginx process writes its own file descriptor to the Nginx.pid, and we need to tell Nginx to reopen a new log file (the configuration details of the log file can be seen here, simply by letting the log record what. So we need this directive:kill -USR1 `cat ${pid_path}`This instruction means: first cat to Nginx PID, is an integer, and then send the signal
