Hack the box —— Emdee five for life wp

打开题目发现这是一道20分值的web题目

提示：Can you encrypt fast enough?（你加密的够快吗）

进入网页

使用md5加密网站进行加密

他居然说我太慢了

连续试了几次，发现必须得拿出我的pycharm写代码了

 

思路：得到源码->正则匹配加密字符串->MD5加密->post发送。

url = 'http://178.128.41.22:30979/'

r = requests.session()
html = r.get(url)
text = html.text

output = re.search(r'
[a-z|A-Z|0-9]+
', text).group()
output = output.split('>')
output = output[1].split('<')

target = output[0]

final = hashlib.md5(target.encode(encoding='utf-8')).hexdigest()
data = {'hash':final}

posthtml = r.post(url, data=data)
print(posthtml.text)

最后结果
