The pwconv command is used to open the user's projection password. The user and group passwords in the Linux system are stored in files named passwd and group, which are located in the / etc directory. Because of the need for the operation of the system, anyone can read them, creating security flaws. The projection password changes the password in the file to the shadow and gshadow files in the / etc directory, which only allows the system administrator to read it, and replaces the original password with the "x" character, which effectively strengthens the security of the system.
