MTC3 — The new Crypto Cipher Contest

mtc3

Welcome to MTC3!



You like riddles? You always loved to solve the crosswords in your newspaper? Or maybe you are just curious and want to find out about some of the ways to hide a secret (and possibily even to uncover it)? This is your place! Here at MysteryTwister C3 you can solve crypto challenges, starting from the simple Caesar cipher all the way to modern AES we have challenges for everyone. Our challenges range from level I to III, and an additional level X for "mystery" challenges (they may have been unsolved for a long time, mostly we don't know their solution or have no idea whether there is a solution at all). If you are a beginner its probably best if you start trying those challenges that have been solved mostly (see table below). Additional information regarding MTC3 can be found on our about page.

You might want to try some of these

The following table provides you with the list of all challenges currently available. If you are logged in, those are excluded which you already solved or where you are a (co-)author.
The challenges are sorted by default by the ones which have been solved mostly by all users. Alternatively you can also sort the table by content of column [to do this just click on the head of one of the columns "Challenge name", "Level", "# times solved" or "Current points to get"].
"Current points to get" shows how many points you get when you submit the solution today. By clicking on the challenge name within the list you will be taken directly to the corresponding challenge and can start solving it.
Score hunters try those challenges that yield the highest available points. Accordingly, those will be harder! Test your skills! Besides using the table below there is also a detailed list of all challenges



Check, which levels to show Level I Level II Level III Level X
If you are logged-in this list will only show those challenges you haven't solved yet.
