To make it

@a =
(0..9,A..Z,a..z); # password charactors
@b =
(6..14); # length of password
for($I=0;$I1000;$I++)
{
for($x=0;$x$b[rand @b];$x++) {
print
$a[rand @a];
}

you can use crypt():
#!/usr/bin/perl -w
use strict;
print generate_password(), \n for 1..1000;
sub generate_password
return(substr(crypt(,join('',(0..9,'A'..'Z','a'..'z')[rand 62,rand
62])), -8 ));
}
if you want to check if the same string is generated, you can write some
control
