Found this fun puzzle to solve in an MIT free computer network+security course: 6-857-network-and-computer-security-spring-2014
Problem 1-2. One-time pad with ciphertext feedback: (a) Here are two 8-character English words encrypted with the same “one-time pad”. What are the words?
e9 3a e9 c5 fc 73 55 d5 f4 3a fe c7 e1 68 4a df
My solution is not the most elegant, but works via XORing the 2 ciphertexts, and using dictionary attack of 8 letter words XOR'd with this key. To get these 8 letter words I parsed a dictionary file found at https://github.com/dwyl/english-words.
I did have trouble figuring out which message was which. It seemed there would be no logical way to tell, the professors answer confirmed this.
