我一直在研究一个 Python 程序,该程序搜索多个 IP 地址范围并检查 SSL 证书/从中读取某些信息,然后将其写入 CSV 文件。

我现在遇到的问题是,我要搜索的一些 IP 地址可能在同一个 IP 地址上有多个域名。我一直在四处寻找并尝试为此提出某种类型的解决方案,但似乎没有太多关于在 OpenSSL 中使用 SNI 检查 IP 地址的文档

此外,我遇到的另一个问题是我想从证书中获取服务器类型(例如 apache、nginx 等),但 OpenSSL 似乎没有提供该信息。另一方面,Curl 确实如此,我实际上是在使用 curl 来确定是否在 IP 地址上找到了证书——我只是不知道如何从 curl 的输出中获取该信息。

如果有人可以就如何实现上面列出的两个功能给我一些意见,我将不胜感激

这是我到目前为止的代码(请原谅非常长的硬编码线程——我没有机会清理它):

from subprocess import *

    global IP_list
    IP_list = []

    global certInfoHolder

def getRanges():
    print 'Enter a range(ex. From: 192.168.1.0 , To: 192.168.1.10)'
    starting_IP = raw_input('From: ')
    ending_IP = raw_input('To: ')


    ip_ranges = ipRange(starting_IP, ending_IP)
    addMore = raw_input('Do you want to add another IP range?Y/N')
    addmore = addMore.lower()
    if addMore == 'y' or addMore == 'yes':
        getRanges()

    elif addMore == 'n' or addMore =='no':
        print 'Done gathering IP Addresses'
        createdThreads = 0
        threadSplit = len(IP_list) / 10

        #Splitting the work up between the threads

SNI

如果我理解正确,您应该能够使用 Python 3.x 系列 3.2+ 到达那里。

如果您被 Python 2 困住,请查看 python-requests 对两个可选依赖项的作用,ndg-httpsclient以及pyasn1.

我的理解是,由于开发人员令人困惑地认为SNI 在某种程度上是 Python 的一个特性,所以你不能用纯 Python <= 2.7.8 做很多事情

编辑

感谢PEP466,Python 2.7.9 包含从 Python 3.4 反向移植的 ssl 模块,并且您拥有所有 OpenSSL 功能。

其他的项目

也许sslyze (github)已经可以做你想做的事了?
