Four levels

Four levels of increasing difficulty: From pen & paper to complex mathematical problems.

Limited attempts

You have only a limited number of attempts to solve each challenge. Be certain of your answer before you submit it.

Be fast

Be fast and earn a place on the Hall of Fame. The first four to solve each challenge will be displayed permanently.

Special Level X

The special level X contains cryptographic problems which are currently not known to have been solved.



Cipher challenges on four levels

 

Level I crypto challenges

Level I Challenges - Pen & Paper

Level I challenges are similar to crossword puzzles from newspapers and can be solved with little cryptographic background. You might not even need a computer for solving level I challenges — all you need is a bit of clever thinking and probably a pen and paper. A program like CrypTool applied to a level I challenge can help reveal the answer within minutes or even seconds, if the necessary algorithms are already built in. Hence, if you are new to cryptography, but nonetheless interested in the mysterious topic of cryptanalysis, give the level I challenges a try. You will almost assuredly meet quickly with success.
 
Level II crypto challenges

Level II Challenges - Programming skills required

Level II challenges require some background knowledge in cryptology and usually some computational power. Additionally, you may require tools that are not available in such convenient packages like CrypTool, OpenSSL or Sage. Therefore, you must first thoroughly understand the problem in order to write a computer program, which helps you getting along. It could take hours or even days to solve a level II challenge. Hence, if you consider yourself well-armed with cryptologic knowledge (such as if you are a university student in a cryptographic course), give the level II challenges a try. Success may not come easily, but it will be a worthwhile endeavor.
 
Level III crypto challenges

Level III Challenges - Extensive computing power recommended

Level III challenges require a thorough background in cryptanalysis and usually significant computational power as well. The problems in this level represent current research topics that are believed to be very difficult to solve. Thus, practical solutions may not even exist and ready-to-run tools almost certainly do not. The methodology to solve some of these challenges may already be known, but it may require such a huge amount of computational power that only a large group of people working together in a distributed system could obtain the solution. Challenges in this category mark the thin line between algorithms that are still secure and those that are not. Solving them may take weeks or even several months. Hence, challenges in this level are intended for entire research groups with many experts in cryptanalysis, programming, and distributed systems. Success cannot be guaranteed, but if you are the first to successfully solve one of these challenges, it probably would catch the attention of the scientific community. Of course, it still remains up to you to publish or present any such scientific techniques and results.
 
Level X crypto challenges

Level X Challenges - Unsolved ciphers

Most level X challenges contain problems that have remained unsolved for a long time. The fact that they have been unsolved regardless of numerous attempts suggests these challenges being hard. However, a simple idea can probably reduce the difficulty of it to a simple level I challenge — currently it is just unknown if and how they can be solved. Of course such a challenge cannot be solved with a simple codeword, since even we (the respective author and the MTC3 team) do not know the solution (the plaintext, the original message or the approach). So if you discover a promising solution you should either contact the author or the MTC3 team. Furthermore, you can publish your findings in a scientific journal such as Cryptologia or Journal of Cryptology.

 

Additionally, you may require tools that are not available in a convenient package like CrypTool.

Monoalphabetic Substitution

[esslinger-02] - 475 users already solved this challenge, 153 are working on it.
 
 
 

This is a famous speech of a German soccer star - including a mistake. The codeword consists of 2 words, one after the other with no space. The first is the password used to encrypt the plaintext, and the second is the mistake in the decrypted text. (The plaintext is in German.)

Ku Klux Klan

[schmeh-06] - 36 users already solved this challenge.
 
 
 

In 1923, a member of the Ku Klux Klan sent an encrypted telegram to one of his colleagues. This telegram could be preserved.

More than 60 years later, the US mathematician Cipher Deavours examined the telegram and was able to decipher it. In 1989, he published some of the details about the solution in the magazine Cryptologia („A Ku Klux Klan Cipher“, edition 3/1989). However, he didn‘t tell the complete solution – the last part was left to the reader as an exercise.

Beale Ciphers

[schmeh-04] - 1 user already solved this challenge.
 
 
 

In 1885, the US businessman James Ward published a booklet about an allegedly true story of a hidden treasure. According to the story, in 1823, a man named Thomas Beale hid several tons of gold and silver in a secret place and described the location of it in three encrypted messages. One of these messages was cracked, but it doesn't contain enough information to locate the treasure.

The two other messages are unsolved.
