Hi
Here is a working copy of code to encrypt / decrypt text based on Crypt::CBC using Rijndael Cipher. This is just to demonstrate that this is possible in perl.
Argument 1 to program is your key eg : 1234 and Argument 2 is a file to store the encrypted text
$perl crypt.pl 1234 crypt.txt 

#! /Users/XXX/perl5/perlbrew/perls/perl-5.20.0/bin/perl
use strict;
use lib "/Users/XXX/perl5/perlbrew/perls/perl-5.20.0/lib/site_perl/5.2
+0.0/darwin-2level/Crypt/"; 
use Crypt::CBC;
#use Crypt::Rijndael;

my $cipher = Crypt::CBC->new( -key => $ARGV[0],
                              -cipher => 'Rijndael'
                            );  

my $ciphertext = $cipher->encrypt("texttoencrypt");
open(my $fh,">",$ARGV[1]);
print $fh $ciphertext;
close $fh;
my $plaintext = $cipher->decrypt($ciphertext);
print "ciphertext " , $ciphertext,"\n";
print "plaintext " , $plaintext,"\n";

In order to get a better understanding of how the Crypt::CBC module works , the options and how to invoke the different methods look no further that metacpan.org where the module is documented.
If you are new to perl ,do skim through perldoc perlintro first, to understand basics about perl and pointers to the larger documentation set.

The temporal difficulty with perl is u need to know C well to know the awesome.else u just keep *using* it and writing inefficient code
