The programming project (Python) consist of 3 basic steps: 1. AES-CBC mode encryption (use PKCS#7 padding, give 128-bit key, give 128-bit IV) 2. Decryption, and check if plaintext is well formed under padding (yes or no). 3. Repeat step 1. This time, launch the padding oracle attack (PKCS#7) to gain plaintext (attacker knows ciphertext, IV, and length of plaintext, try to find plaintext) I will send you more detailed instruction. Most information are same. Give necessary comments in the code. One day should be enough for experienced guys because there are so many sample codes on GitHub.
