question:HITSS{5X65Z1ZXZ10F_E1LI3J}files: [script.py](script(4).py)- based on the name we can assume it's a substitution cipher
looking at the script we get:alpha = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ{}_1234567890'key   = 'QWERTPOIUYASDFGLKJHZXCVMNB{}_1234567890'
text = <flag>
def encrypter(text,key):    encrypted_msg = ''    for i in text:        index = alpha.index(i)        encrypted_msg += key[index]    # print(encrypted_msg)    return encrypted_msg
- looks like a 1 for 1 substitution using the included key.
1) copy paste the flag into a txt called flag2) translate from key to alpha `cat flag | tr 'QWERTPOIUYASDFGLKJHZXCVMNB{}_1234567890' 'ABCDEFGHIJKLMNOPQRSTUVWXYZ{}_1234567890'`- output:SHELL{5U65T1TUT10N_C1PH3R} **flag: SHELL{5U65T1TUT10N_C1PH3R}**
