MysteryTwister (MTC3)


This time we are really happy to announce...

that experts in the field of cryptography have joined the wechall network.

The new challenge site joining is "", which is part of the famous open-source project CrypTool, known amongst challengers.

CrypTool is an academic approach to teach the mathematics behind cryptography in an experimental manner by offering three offline e-learning programs (CT1, CT2, and JCT), the website CrypTool-Online, and the MysteryTwister crypto contest.

The puzzles on MTC3 are, of course, of cryptographic nature, and quite some of the problems are yet unsolved.

MTC3 has almost 9000 players from all around the world and the ciphertexts are presented in English and German. There is an active forum to discuss the problems in a non-spoiling, moderated manner.

Currently there are 260 challenges by more than 50 different authors, offering everything about crypto and computational number theory I can imagine -- from classical ciphers (Caesar, Vigenère, Hill, ...) to modern symmetric and asymmetric crypto (ORYX, AES, RSA, ECC, Lattice, homomorphic, DSA, ...).

So if you need a warmup or a fresh excourse in cryptography, this surely is a place to look at.

The site is scheduled with 10,000 basepoints, and the wechall score also includes old and inactive challenge sets.

The project lead Bernhard Esslinger is looking forward to your feedback and, maybe, a yet unsolved challenge to be cracked.

We all hope that many of you discover something new while trying out the site and wish you...

Happy Challenging!
