About to what point ? <| sep |> Steganography with no pictures coupled with even basic encryption is fairly powerful . The SNOW method of white space encoding on the end of say a json file is pretty hard to spot and if a secure one time pad is used for encryption the message is nearly uncrackable . <| sep |> This is how every Kickstarter has worked , and it is confusing seems like just a limitation of KS itself . When he reveals new expansions during the campaign , they will also say how much it will cost . You then select Manage Pledge on the KS page , and you update the dollar amount with the price of the expansions you want . For example , I got the $ 300 pledge tier . However , to get the First Heroes expansion , I would select Manage Pledge and change the dollar amount of my pledge to $ 335 . This doesn ' t change the reward tier you are at . After the campaign at some point , they will send out a link to a pledge manager website which will have your tier you ordered , along with the dollar amount . So , it will know I got the $ 300 tier , and that I added an additional $ 35 to spend . From there , I select the actual expansions I want like I ' m adding them to a shopping cart . For example , if they release multiple expansions at $ 35 each , but I only want one , I can then select the specific one I want then . tldr On your existing pledge on the Kickstarter website , just add the money for each expansion you want and it will get worked out later . All that ' s important now is the dollar amount , not choosing the addon expansions you want .
