... can you please tell me what the following means from your code.

?:\s+|$) /mgx
also

Q$password\E}

This should be  (?:\s+|$) (a non-capturing grouping),
and  s{Password=\Q$password\E}{...} (the match regex of a substitution).

To explain these: 

c:\@Work\Perl\monks>perl -wMstrict -le
"use YAPE::Regex::Explain;
 ;;
 print YAPE::Regex::Explain->new('(?:\s+|$)')->explain;
 ;;
 my $password = 'f+o*o?[ ]b{}r';
 my $regex = qr/Password=\Q$password\E/;
 print YAPE::Regex::Explain->new($regex)->explain;
"
The regular expression:

(?-imsx:(?:\s+|$))

matches as follows:

(?-imsx:                 group, but do not capture (case-sensitive)
                         (with ^ and $ matching normally) (with . not
                         matching \n) (matching whitespace and #

                             possible))

The regular expression:

matches as follows:
