해결책

접속하면 일련의 이진수가 보인다. 8자리씩 잘라서 읽는 문제일 듯싶다. 

코드를 열심히 짜고 있었는데, 이거 번역해주는 사이트가 있더라

"NVCTFDV KF JLEZERKRJ REU KFURP ZJ R XFFU URP REU RLKYBVP ZJ GCRZUTKWZJMVIPYRIU"

라는 글이 나왔다. 대충보면 ROTATION암호인데, 돌려보면 될 거 같다. 

### 19.py

if __name__=="__main__" :
    raw = "NVCTFDV KF JLEZERKRJ REU KFURP ZJ R XFFU URP REU RLKYBVP ZJ GCRZUTKWZJMVIPYRIU"

    con = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"

    for i in range(26) :
        tra = con[i:]+con[:i]
        print(raw.translate(raw.maketrans(con,tra)))

출력은 다음과 같다.
