I have 10 cipher texts ciphered with One Time Pad (OTP) using the same key.
I need to recover the key (or in other words, to recover the 11th cipher text which I assumed would require me to recover the key first).
I followed a technique called "Crib Drag" described in: Taking advantage of one-time pad key reuse? Simply, by XORing the word " the " (including spaces) with the result of (C1 XOR C2), I could recover 5-letters that make sense to me that it is a plain text.
However, I do not know whether this plain text belongs to P1 or P2.
Can you help me how to know if the plain text belongs to P1 or P2 ? How can I recover the key bytes if I could recover letters from P1 or P2 ? How can I check whether they belong to P1 or P2 ?
I tried several attempts but no hope. Please, help me to continue and recover the key using this method.
