How to Generate Random Passwords

require MIME::Base64;
use strict;

my $r = sprintf("%08d", int( (1000000000) * rand() ));

my $password = MIME::Base64::encode($r);
   $password =~ tr/A-Z/a-z/;
   chomp $password;

$password =~ s/[^a-z]//g; # remove other chars than alphabetic

$password =~ s/0/z/g;
$password =~ s/o/x/g;
$password =~ s/j/k/g;
$password =~ s/q/r/g;
$password =~ s/y/s/g;

$password = substr($password, 0, 6);

my @vocals = qw ( a e i u ) ;

my $rand_voc = $vocals[ int(rand() * 4) ];

substr($password, 1, 1) = $rand_voc if substr($password, 0, 1) !~ /[aeiou]/;
substr($password, 2, 1) = $rand_voc if substr($password, 1, 1) !~ /[aeiou]/;
substr($password, 3, 1) = $rand_voc if substr($password, 2, 1) !~ /[aeiou]/;
substr($password, 4, 1) = $rand_voc if substr($password, 3, 1) !~ /[aeiou]/;

$password .= sprintf("%02d", int(rand() * 99) + 1);

#####  print pw
print "password => '$password'\n";

Get a random element from an array

my @list = qw( foo bar car );

my $any = $list[rand($#list + 1)];

print "$any\n";

(From unknown source)

#!/usr/bin/perl -w

print "Enter a seed number: "; $s=<STDIN>;
srand($s ^ time);
@c=split(/ */, "bcdfghjklmnprstvwxyz");
@v=split(/ */, "aeiou");
for($i = 1; $i <=4; $i += 1)
{ print $c[int(rand(20))], $v[int(rand(5))] }
