Create Password

/**
 * Class to define a password. A password object is a string of symbols, letters
 * and/or digits of 8-12 character length. The password is encrypted using a 
 * password salt and a hash algorithm and stored in the files etc/passwd and
 * etc/shadow. When the system must determine if passwords match it compares
 * encryption results to see if they match.
