secure curl POST

in my new script i am using two servers ..

one for database and php files

and one for files uploaded by users , like exe , mp3 , etc ..

from control panel on the first server , they can delete them files on the second server ..

my question is :

i am using curl to do this job

i am sending 2 POST information by curl

1 - some password for my site 2 - the job what i want do ! , like , delete file , make new folder ...

examples for the curl function :
$post = array('password'=>'Mywebsite开发者_JS百科password','command'=>'make new folder');

example for the file on the second server

if($_POST['password'] and $_POST['password'] == Mywebsitepassword){
  it's ok
}

Now the password is 'Mywebsitepassword'

if some one can know it , he will be able to delete all my second server content !!

is any addone or some way to know it ??

may be some addone for firefox can know it or something like that

Just make sure you do your stuff over a secure connection (SSL).
