python—base64

Posted 2020-11-27 anweilx

今天在写题时，执行脚本又报错了

脚本如下

#! /usr/bin/env python3
# _*_  coding:utf-8 _*_
import base64

# 字典文件路径
dic_file_path = \'./10_million_password_list_top_100.txt\'
with open(dic_file_path, \'r\') as f:
    password_dic = f.readlines()

username = \'admin:\' # 用户名
for password in password_dic:
    encodestr = base64.b64encode("admin:" + password.strip())
    print(encodestr)

 

报错如下

Traceback (most recent call last):
  File "D:/python file/ctf/ctfhub http 基础认证密码/密码payload生成.py", line 12, in <module>
    encodestr = base64.b64encode("admin:" + password.strip())
  File "D:\\obj\\windows-release\\37amd64_Release\\msi_python\\zip_amd64\\base64.py", line 58, in b64encode
    encoded = binascii.b2a_base64(s, newline=False)
TypeError: a bytes-like object is required, not \'str\'

上面最后一句话的意思是“类型错误：需要类似字节的对象，而不是字符串”。

于是更改为如下脚本

#! /usr/bin/env python3
# _*_  coding:utf-8 _*_
import base64

# 字典文件路径
dic_file_path = \'./10_million_password_list_top_100.txt\'
with open(dic_file_path, \'r\') as f:
    password_dic = f.readlines()

username = \'admin:\' # 用户名
for password in password_dic:
    str1=str.encode(username + password.strip())
    encodestr = base64.b64encode(str1)
    encodestr=str(encodestr)
    encodestr=encodestr.strip(\'b\\\'\')
    encodestr=encodestr.replace("=","\\=")   #避免“=”被转译
    print(encodestr)

成功运行
