For a while I toyed around with the idea of being able to prove my predictions were in fact correct, but I could never seem to find an easy way to do so without the other person knowing what my prediction was going to be. If they know what my prediction is, they can influence the outcome in their favour. Hence this project was brought into life, to prove me right for once and for all.
Now, this project had to be reliable and trustworthy in order to be taken serious. I had to make sure that I could prove the prediction was not tampered with. The way I ended up doing this was by making a hashed version of the message using the given message together with a salt, as otherwise it would be rather easy to rainbow table the possible predictions somebody may have made ahead of time. You can find this feature back in the integrity checker, which will run automatically as soon as the message and salt become available.
Is it completely tamper proof? No. Editing the hash and message could still make it seem like a message has not been tampered with, even if it has. If you care as much about the integrity of the message, then it is best to save the hash locally and verify if it still matches by the time the message becomes public. Only then can you truly know the message has not been altered. The hashed version of the message is for that reason always available, before and after the message has become public.
Yes, this was very much a work of passion. I thoroughly enjoyed the project and the many times it has proven me right ever since. Although it has become more than just a way to prove my predictions justice, it now also allows me to share self destructable messages which will only be visible between a given timeframe. If somebody really cares about the content of the capsule, will they bother waking up at 3 AM to see a message that will destruct itself after 5 minutes? That's something you'll have to find out for yourself.
