This is pathetically weak and should never be used for any purpose other than maybe as homework to break in the first week of cryptanalysis 101.

  Yes, if the file size is small then an attack is possible. But if it's big, it's really very difficult. I'm also working on a pre-mask that removes repeating bytes from the input and makes it impossible to get double characters. It's just an experiment, I'll also put an encrypted file with a prize for whoever reveals the original file! Apart from these problems that are there, how are you going to guess a sequence that can have 256! different combinations and can be encrypted with several different keys?

Good idea. > how are you going to guess a sequence that can have 256! different combinations and can be encrypted with several different keys? Because there are other attacks possible besides just brute force.
