comment SHA256-based stream cipher
Thank you @figlesquidge . I've rescinded my close vote; the question is still too broad but at least it goes well with your answer so I guess that's ok.

comment SHA256-based stream cipher
Please include enough information to make your question self-contained. Note that we do not do full reviews of crytographic schemes (“is this scheme secure?”). We can provide feedback about specific properties (”is this step vulnerable to this type of attack?“). If you edit your question, take care not to invalidate figlesquidge's answer.

comment How to attack a classical cipher using known partial plaintext?
Welcome to Stack Exchange. This answer would be more interesting if you described some algorithms to detect classical ciphers, rather than just linking to some code (whose operating principle isn't even described, at least not at that URL).
