Function Description: Open the group's projection password.

Syntax: Grpconv

Supplemental Note: The user and group passwords in the Linux system are stored in the passwd and group files in the ETC directory respectively. Anyone can read them because of the operation of the system, creating a safety flaw. The projection password changes the password within the file to the shadow and Gshadow files in the ETC directory, allowing only the system Manager to read and replace the original password with the "x" character. The function of the projection password can be turned on or off at any time, you can only execute the GRPCONV instruction to open the group projection password.
