I am brand new to the world of cryptogrophy. I am trying to decrypt a many-time-pad. I understand the methodology of using the XOR to get the messages.
C1 XOR C2 = M1 XOR M2
Now my question lies in a specific case. I have about 11 cipher texts with a number down the same index. All of them either have a '2', '3', or '4'. I am completely lost on how to decrypt this key index. If the cipher texts are the same, then it means if I XOR them together I get a ASCII 0 value, I don't know how that helps me. Anything XOR 0, is that anything. So is the message itself contain a integer at that location? Is my key a 0? I doubt that 11 cipher texts would have a number at the exact same spot, seems odd.
How would I go on about getting the key at this specific spot?
