Quick Q&A
What can I do here?
If you ended up here by clicking on a hash link, just fill in the form above and see if you guessed right. Capitalization and spaces don't matter. E.g. "a B C" is the same as "ABC", "abc", or "aBc". Unicode characters also work as intended.
If you guessed right you can start the next round. Enter up to 5 different answers and paste the generated link over at that forum (or whereever you want).
You can of course also start anew if you like.
What's the benefit of using this tool?
The biggest issue with those "guess the game/anime/movie" threads are the bloody long roundtrips. You guess, you've to wait (up to a few hours) until the submitter of the current image answers, a bit more time passes until you read the answer (can take a few more hours depending on time zones), and then you'll know if you were right.
This sort of drag somewhat ruins most of the fun and it often slows the turn-over rates down to a crawl. With this tool those "submitter pings" can be completely bypassed, which means you can start the next round right away. Well, if you guessed right, that is.
How does it work?
A cryptographic hash function is used to store the "fingerprints" of answers in the generated URL. The answers itself aren't stored anywhere.
If a user enters some answer its hash is calculated and then this hash is compared with the hash(es) from the URL. If the hashes are equal both inputs were most likely also equal. Those cases where the inputs weren't equal are so called collisions. Fortunately they are rather unlikely. It's virtually impossible that a plausible answer will result in a collision.
How well are the answers hidden?
Not much, really. With enough time and processing power the answer (among a pile of collisions) can be retrieved with a brute force attack. Even more so if the number of possible input values is somewhat limited (e.g. all animes, movies, or games ever released).
Fortunately this attack vector is amazingly boring and unleet. As long as there aren't any prizes involved no one will bother. Assembling massive lists by parsing Wikipedia? Bleargh! That's so unimpressive. ;)
