To sign a comment client side to prevent against server side tampering you need to sign it client side . Signing client side in a browser means you ' re using JavaScript . Assuming a typical end user browser environment , what stops me as the server owner from pushing certain clients extra JavaScript which waits for you to submit a post , then uses your pass phrase entry processed in the JavaScript from using your client side passphrase and key to make new posts or edit existing ones ? <| sep |> Are you Norwegian ? Riksml sounds really off to me , and I think it would for most Norwegians . I don ' t know what you mean with bokml , yeah , it is flexible in how it lets you express things , to accommodate the many dialects in use , but still it ' s a standard that is being taught that are stricter , and secondly , you can ' t force the rest of Norwegians to speak it , and there is almost nothing written in riksml , and none speaking it never met a soul speaking it in 30 years in Norway so you ' re seeing yourself up to a world of frustration learning it .
