Hi,
I am trying write a module for encrypt and decrypt. And in my main perl program , i would like to call the encrypt and decrypt method. First time i am writing a module. So can any one help me to do how should i call the encrypt and decrypt function.
Following are my module code

package Config::Confmanager;
use Exporter;
#export all the methods
@EXPORT=qw(&Encrypt,&Decrypt);
use warnings;
use strict "refs";
use Crypt::CBC; #CPAN Module For Encryption And Decryption  

#Creating Constructor;
sub new
{
      my($self) = {};
        bless ($self);
        return ($self);
        
}
#---------------------------------------------------------------------
+----------------------------------------

                #Encrypt And Decrypt Method
#---------------------------------------------------------------------
+---------------------------------------

sub CreateEncryptDecryptObject
             {
    $cipher = Crypt::CBC->new( {'key'       => 'passport',
                              'cipher'          => 'DES',
                              'iv'              => '$KJh#(}q',
                              'regenerate_key'  => 0,   # default true
                              'padding'         => 'space',
                              'prepend_iv'      => 0
                           });
                       }

#---------------------------------------------------------------------
+----------------------------------------

                    #Encrypt  Method
            #Takes An Option Value As Plain String And Encrypts It

#---------------------------------------------------------------------
+---------------------------------------
sub Encrypt

{ 
    CreateEncryptDecryptObject();
    my($encryptstring) = @_;

    my $cipherencryptstring = $cipher->encrypt($encryptstring);
    if (!$cipherencryptstring) 
        {
    $log->error("Could not Encrypt requested string\n",); 
        return ;
    
        }
else
        {  return($cipherencryptstring); }
              
} 
#---------------------------------------------------------------------
+-------------------------------------------
                    # End Of Encrypt Method
#---------------------------------------------------------------------
+---------------------------------------------


#---------------------------------------------------------------------
+----------------------------------------

                    #Decrypt Method
            #Takes An Encrypted String  And Decrypts It

#---------------------------------------------------------------------
+---------------------------------------
sub Decrypt
{
    CreateEncryptDecryptObject();
    my($decryptstring) = @_;
    my $cipherdecryptstring = $cipher->decrypt($decryptstring);
    if (!$cipherdecryptstring) 
        {

    $log->error("Could not Decrypt requested string\n",); 
    exit;
        }
else
        { return($cipherencryptstring); }
}

1;
