code: function(ue){// Shortcut
  var be=this._hasher,he=be.finalize(ue);// Compute HMAC
  be.reset();var me=be.finalize(this._oKey.clone().concat(he));return me}
docs: Finalizes the HMAC computation.
  Note that the finalize operation is effectively a destructive, read-once operation.
  
  @param {WordArray|string} messageUpdate (Optional) A final message update.
  
  @return {WordArray} The HMAC.
  
  @example
  
  var hmac = hmacHasher.finalize();
  var hmac = hmacHasher.finalize('message');
  var hmac = hmacHasher.finalize(wordArray);
