Why Addition Mod 32? Thank you for your prompt and clear response, this makes much more sense now. |

Is XOR in a CBC-like mode secure? The idea I had for the key is that the user provides a key of n-bytes, then the plaintext is divided into n-byte blocks, padded if necessary, and then for each block, you run the algorithm. |

Is XOR in a CBC-like mode secure? Yes, the title was edited by Ninefingers, and the reason I don't use the ciphertext to encode more ciphertext is that would seem insecure, because the previous byte of ciphertext is known to a possible attacker, while the previous byte of plaintext is encrypted. |
