How to decrypt AES in CBC If I understand you correctly, what you're doing is correct only if your "block cipher" is simple XOR, which in all likelihood it is not (unless the guys in Coursera gave you a somewhat esoteric assignment). More likely you should be using some "real" block cipher here. Furthermore, a ciphertext will usually not look "reasonable" no matter what. You know you have it right when you can decrypt it back to plaintext. |

How to decrypt AES in CBC CBC only says basically that C_t = ENC_k(C_{t-1} XOR P_t). ENC_k here is the encryption operation of the block cipher (whichever you choose, for example AES-128) with the key k. That's all. The details are a matter of the choice of the specific block cipher. |
