ORYX Stream Cipher Part II

[stamp-02] - 47 users already solved this challenge, 3 are working on it.
 
 
 

The ORYX stream cipher consists of three 32-bit LFSRs X, A, B which are shifted differently depending on some bits in the LFSR X. The key stream is a combination of the highest 8 bits of each of the three LFSRs. It is neither feasible nor necessary to search the whole 96-bit key space, there are more efficient methods!

Hint: Enter the codeword in hex with non-capital letters and a leading zero.

Not-so-Secret Message from Malawi — Part I (RSA)

[schaefer-01] - 188 users already solved this challenge, 4 are working on it.
 
 
 

When creating RSA keys, it is important to choose the n and e parameters wisely. This was not done in this example, and thus you should be able to decipher this ciphertext message sent from Malawi. The plaintext gives the codeword, which is related to the photo.

Sigaba Part 1

[stamp-07] - 16 users already solved this challenge, 1 is working on it.
 
 
 

The encryption with the Sigaba machine was the American counterpart to the German Enigma. But due to the much larger key space of the Sigaba, even today, it is only feasible to break the code if parts of the key are known. This is what this challenge is about.

Brute-Force-Attack on Triple-DES with Reduced Key Space

[shoellhammer-01] - 192 users already solved this challenge, 5 are working on it.
 
 
 

In present-days knowledge Triple-DES is secure if a really random key is used. If the key is not random and a part of the key may be guessed, it is possible to get knowledge of the rest of the key with a feasible bruteforce attack.
