title: Meteor Server: ReferenceError: calcMD5 is not defined
body: <p>Due to some existing mongodb structure. I cant use Meteors <code>Meteor.user</code>. So when I try to insert new user calcMD5 says is not defined. How do I convert Md5 in meteor server? I dont know weather my approach is good or not. correct me if am wrong.</p>
  
  <pre><code>if (Meteor.isServer) {
   newUser: function(email, password){
    Users.insert({"emailid":email,"password":calcMD5(password)});
   }
  });
  </code></pre>
  
  <p>Here the template code</p>
  
  <pre><code>Template.signInWithEmail.events({
   'click .btn-create-account': function(event, template) {
    email = $('[name="emailAddress"]').val();
    password = $('[name="password"]').val();
  
    //Create new user
    Meteor.call("newUser", email, password, function(error, result) {});
  }
  </code></pre>
