Thank you for your prompt and clear response, this makes much more sense now.

comment 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.

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.

Thanks, Ninefingers! You're right, I had no idea what to put as the title.
