忘记ios访问限制密码

1、使用iTunes将手机备份在本地。

2、下载iBackupBot，打开后在左侧可以看到你的历史备份，选择刚刚备份的文件。依次选择System Files -> HomeDomain -> Library，之后在右侧搜索框搜索文件com.apple.restrictionspassword.plist 并打开。获得RestrictionsPasswordKey和RestrictionsPasswordSalt的值。

3、运行这段python代码，输入RestrictionsPasswordKey和RestrictionsPasswordSalt的值计算即可，原理就是从0000到9999暴力穷举计算。

 import hashlib
 import string
 import base64
 import itertools
 import os
 import sys

 def calc_key(myKey, mySalt):

     for i in itertools.product(range(10), repeat=4):
         nPass = ''.join(map(str, i))

         code = hashlib.pbkdf2_hmac('sha1', nPass.encode(), base64.b64decode(mySalt), 1000, dklen=None)

         if base64.b64encode(code).decode() == myKey:
             print ("")
             print ("Your Restrictions Passcode is \"" + nPass + "\"")
             break

 def main():
     restrictionKey = input("Enter your RestrictionPasswordKey: ")
     restrictionSalt = input("Enter your RestrictionPasswordSalt: ")

     if restrictionKey or restrictionSalt:
         calc_key(restrictionKey, restrictionSalt)    

 if __name__ == "__main__":
     main()
