MD5还原

字符串=   TASC?O3RJMV?WDJKX?ZM

残缺的flag = E903???4DAB????08?????51?80??8A?

根据字符串还原flag

import hashlib
for i in range(65,91):
    for j in range(65,91):
        for n in range(65,91):
            a = ‘TASC’ + chr(i) + ‘O3RJMV’ + chr(j) + ‘WDJKX’ + chr(n) + ‘ZM’
            md5_a = hashlib.md5(a.encode())
            if md5_a.hexdigest()[0:4] == ‘e903’:

         print("flag{"+(md5_a.hexdigest().upper())+"}")

运行后得到完整flag
