使用Python获取保存的Wifi密码

在这篇文章中，我们将探讨如何使用Python获取保存在计算机上的Wifi密码。这个功能有很多应用场景，比如当你忘记了自己的Wifi密码时，可以使用这个程序获取。

实现步骤

1. 导入所需模块

import subprocess
import re

2. 执行命令获取Wifi列表

wifi_names = []
results = subprocess.check_output(["netsh", "wlan", "show", "profiles"]).decode("utf-8", errors="ignore")
results = results.split("\n")

3. 使用正则表达式提取Wifi名称

for result in results:
    if "All User Profile" in result:
        wifi_names.append(result.split(":")[1].strip())

4. 执行命令获取Wifi密码

passwords = {}
for name in wifi_names:
    results = subprocess.check_output(["netsh", "wlan", "show", "profile", name, "key=clear"]).decode("utf-8", errors="ignore")
    results = results.split("\n")
    results = [line.strip() for line in results]
    results = list(filter(None, results))
    try:
        ssid_index = results.index("SSID name              : {}".format(name))
        key_index = results.index("Key Content            :")
        password = results[key_index + 1]
        passwords[name] = password
    except ValueError:
        passwords[name] = ""

代码片段

import subprocess
import re

wifi_names = []
results = subprocess.check_output(["netsh", "wlan", "show", "profiles"]).decode("utf-8", errors="ignore")
results = results.split("\n")

for result in results:
    if "All User Profile" in result:
        wifi_names.append(result.split(":")[1].strip())

passwords = {}
for name in wifi_names:
    results = subprocess.check_output(["netsh", "wlan", "show", "profile", name, "key=clear"]).decode("utf-8", errors="ignore")
    results = results.split("\n")
    results = [line.strip() for line in results]
    results = list(filter(None, results))
    try:
        ssid_index = results.index("SSID name              : {}".format(name))
        key_index = results.index("Key Content            :")
        password = results[key_index + 1]
        passwords[name] = password
    except ValueError:
        passwords[name] = ""

结论

通过以上步骤，我们已经成功地获取了保存在计算机上的Wifi密码。如果你需要保存这些密码，你可以把它们保存到本地文件中。但是要注意，这些密码应该仅用于个人使用，不应该传播给他人，以保护网络安全。
