# Description Can you conjure the right bytes? The program's source code can be downloaded [here](https://challenge-files.picoctf.net/c_foggy_cliff/b04a1829da5f649435a6903647d126ba60a3d04a250e8f7e3973b2ce121beba5/app.py). Connect to the program with netcat: `$ nc foggy-cliff.picoctf.net 50121` # Hints 1. No copy-pasta, please - use Python! # Solution 下載檔案後,是一個名為 app.py 的檔案 ```python while(True): try: print('⊹──────[ BYTEMANCY-1 ]──────⊹') print("☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐") print() print('Send me ASCII DECIMAL 101 1751 times, side-by-side, no space.') print() print("☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐☉⟊☽☈⟁⧋⟡☍⟐") print('⊹─────────────⟡─────────────⊹') user_input = input('==> ') if user_input == "\x65"*1751: print(open("./flag.txt", "r").read()) break else: print("That wasn't it. I got: " + str(user_input)) print() print() print() except Exception as e: print(e) break ``` \x65 就是 e 我們需要輸入 1751 個 e 就會拿到 flag 所以使用 python 串 nc 就可以了 `python -c "print('e' * 1751)" | nc foggy-cliff.picoctf.net 50121`
