最近在逆向App,重签的时候有时候不知到证书里有没有新加的UDID,所以出现了这篇文章

解释

先获取当前目录下的文件,然后截取后缀名,判断是否有ipa文件

if __name__ == '__main__':
    flag = False
    for filename in os.listdir(os.getcwd()):
        hou = os.path.splitext(filename)[-1][1:]
        if hou == 'ipa':
            flag = True
            unzip_ipa('./' + filename)
            break

    if not flag :
        print('请将ipa放在当前目录')

这里通过zipfile库来读取ipa信息(ipa其实就是zip),然后用正则把plist文件匹配出来,通过plistlib库来加载plist文件,然后打印其中内容.
通过同样的方法匹配出mobileprovision文件的路径,因为需要执行security命令,需要绝对路径,所以临时将mobileprovision文件解压在当前目录,然后使用subprocess执行security命令将mobileprovision文件保存为temp.plist文件,再将其用plistlib加载,读取UDID等信息,最后删除临时解压的文件.

# 解压ipa获取并信息
def unzip_ipa(path):
    ipa_file = zipfile.ZipFile(path)
    plist_path = find_path(ipa_file, 'Payload/[^/]*.app/Info.plist')
    # 读取plist内容
    plist_data = ipa_file.read(plist_path)
    # 解析plist内容
    plist_detail_info = plistlib.loads(plist_data)
    # 获取plist信息
    get_ipa_info(plist_detail_info)

    # 获取mobileprovision文件路径
    provision_path = find_path(ipa_file, 'Payload/[^/]*.app/embedded.mobileprovision')
    # 临时解压
    ipa_file.extract(provision_path, './')
    # 获取当前路径
    current_path = os.path.abspath(os.path.dirname(os.path.abspath(__file__)) + os.path.sep + ".")

    # 获取mobileprovision路径并保存为plist
    string_mobileprovision = string_subprocessPopen('security cms -D -i %s > ./temp.plist' % (current_path + '/' + provision_path),
                                                    None, False)
    temp_plist = './temp.plist'
    #加载plist并获取信息
    with open(temp_plist,'rb') as fb:
        plist_info = plistlib.load(fb)
        print('过期时间:',plist_info['ExpirationDate'])
        print('UDID:' + str(len(plist_info['ProvisionedDevices'])) + '个')
        for i in plist_info['ProvisionedDevices']:
            print(i)
    # 删除临时解压文件
    shutil.rmtree('./Payload')
    os.remove(temp_plist)

打包

使用pyinstaller -F ipa.py命令来打包成可执行文件.
打包成功后再dist目录下有个可执行文件,完成
