Function Description: Open the user's projection password.

Syntax: Pwconv

Supplemental Note: The user and group passwords in the Linux system are stored in files named passwd and group, which are located in the ETC directory. Anyone can read them because of the operation of the system, creating a safety flaw. The projection password changes the password in the file into the shadow and Gshadow files under the ETC directory, only allows the System Manager to read, and replaces the original password with "X" characters, effectively strengthens the system security.
