Re^2: String::MkPasswd still supported?

I took yours now:

#!/usr/bin/perl

use strict;
use warnings;

print mkpasswd({
        minlen => 8,
        maxlen => 10,
        lower => 1,
        special => 1,
        upper => 1,
        digit => 1,
});
        

sub mkpasswd {
    my($param)= @_;
    if( not ref $param ) {
        $param= {
            minlen => $param,
            maxlen => $param,
        };
    }
    if( ref $param eq 'HASH' ) {
        $param->{minlen}||= 8;
        $param->{maxlen}||= $param->{minlen} + 2;
    }
    my ( @l, @u, @n, @s, @p);

    open( URANDOM, "</dev/urandom" ) || die $!;
    read( URANDOM, $_, 4 );
    close URANDOM;
    srand( unpack( "L", $_ ) );

    @l = ( "a" .. "z" );
    @u = ( "A" .. "Z" );
    @n = ( 0 .. 9 );
    @s = (
        '#', ',', ' ',
        qw# ! " $ % & ' ( ) * +  - . / : ; < = > ? @ [ \ ] ^ _ ` { | }
+ ~ #
    );

    push( @p, $l[rand(@l)] ) for ( 1 .. $param->{lower} );
    push( @p, $u[rand(@u)] ) for ( 1 .. $param->{upper} );
    push( @p, $n[rand(@n)] ) for ( 1 .. $param->{digit} );
    push( @p, $s[rand(@s)] ) for ( 1 .. $param->{special} );
    my $m = $param->{minlen} - @p;
    $m=0 if $m<0;
    my $x = $param->{maxlen} - @p - $m + 1;
    $x=0 if $x<0;
    my(@j)= ( @l, @u, @s, @n );
    $x= $m + rand($x);
    push( @p, $j[rand(@j)] ) for ( 1 .. $x );
    

    for ( my $i = @p ; --$i ; ) {
        my $j = int( rand( $i + 1 ) );
        next if $i == $j;
        @p[ $i, $j ] = @p[ $j, $i ];
    }

    return join( "", @p );

}
