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.

WebWith the XOR operation, the decryption operation is simply the same as the encryption one. 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. WebChallenge 9 - Implement PKCS#7 padding. ¶. A block cipher transforms a fixed-sized block (usually 8 or 16 bytes) of plaintext into ciphertext. But we almost never want to transform a single block; we encrypt irregularly-sized messages. One way we account for irregularly-sized messages is by padding, creating a plaintext that is an even ...
