Buuctf-crypto-丟失的MD5

首先打開之后是一個py文件，本地跑一下，出錯

 

 顯示說，

 

 源碼為：

import hashlib   
for i in range(32,127):
    for j in range(32,127):
        for k in range(32,127):
            m=hashlib.md5()
            m.update('TASC'+chr(i)+'O3RJMV'+chr(j)+'WDJKX'+chr(k)+'ZM')
            des=m.hexdigest()
            if 'e9032' in des and 'da' in des and '911513' in des:
                print des

　　

修改后：

import hashlib
for i in range(32,127):
    for j in range(32,127):
        for k in range(32,127):
            m=hashlib.md5()
            m.update('TASC'.encode('utf-8')+chr(i).encode('utf-8')+'O3RJMV'.encode('utf-8')+chr(j).encode('utf-8')+'WDJKX'.encode('utf-8')+chr(k).encode('utf-8')+'ZM'.encode('utf-8'))
            des=m.hexdigest()
            if 'e9032' in des and 'da' in des and '911513' in des:
                print (des)

　　

運行之后得flag
