WebOct 21, 2024 · This challenge asks us to detect whether we’ve encrypted a text with ECB or CBC, chosen at random. Recall the properties of ECB vs CBC — ECB will take two identical plaintext blocks and produce two identical ciphertext blocks. So just detect ECB using the function in challenge 8. If it's ECB, return ECB. If not, return CBC 2.12. WebCongratulations. This is the first challenge we've given you whose solution will break real crypto. Lots of people know that when you encrypt something in ECB mode, you can see penguins through it. Not so many of them can decrypt the contents of those ciphertexts , and now you can.

This is because of the following property of the XOR operation: XORing twice by the same value gives back the original value. That is, for all bytes (or bits, or bytestrings) A A and B B, we have: (A⊕B)⊕B = A ( A ⊕ B) ⊕ B = A. ease baby teething pain
