Hey , I lost my leg in a car accidentOh , really ? ? I ' m so sorry to hear that . Are you okay ? Hows your recovery going ? Rehab is going fine , but I ' m a bit depressed . God I wish I ' d just worn my seatbelt . Oh , so you didn ' t wear your seatbelt ? lol you fuckin idiot you deserved it . no sympathy for you . <| sep |> The signature will show you which private key was used to sign by checking with the public key . If the signature was made with the same private key as last time , then you know it ' s a comment by the owner of the private key . Only problem is that we need an API for the browser to create , use , and export a private key to local disk . Then you only need to trust another user the first time you see a comment , and that trust may build over time . But that is a completely new ballgame in which multiple scientist are still seeking eternal fame by figuring it out .
