使用 openssl、requests 和 wincertstore 获取客户端证书

问题描述

我有代码可以遍历我的 wincertstore 并按名称和/或指纹查找证书。

if os.name == 'nt':
    for storename in ["MY"]:  # "ROOT","CA",with wincertstore.CertSystemStore(storename) as store:
            for cert in store.itercerts(usage=wincertstore.CLIENT_AUTH):
                print(cert.get_name())
                print(cert.cert_type)
                print(cert.enhanced_keyusage_names())
                # pem = cert.get_pem()
                # encodedDer = ''.join(pem.split("\n")[1:-2])
                # cert_bytes = base64.b64decode(encodedDer)
                cert_pem = ssl.DER_cert_to_PEM_cert(cert.get_encoded())
                cert_details = x509.load_pem_x509_certificate(
                    cert_pem.encode('utf-8'),default_backend()
                )
                serial_number = hex(cert_details.serial_number).replace("0x","")
                cert_details.fingerprint
                if cert.get_name().lower() == find_name.lower():
                    pem_data = cert.get_pem()
                    break
if pem_data:
   f = open('./mycert.pem','w')
   f.write(pem_data)
   f.close()
   del f

import requests 
resp = requests.get(<some url>,cert='./mycert.pem')

这会导致 SSL 错误：

urllib3.exceptions.MaxRetryError: HTTPSConnectionPool(host='*****.e***.com',port=443): Max retries exceeded with url: /gis/sharing/rest/portals/self/servers?f=json (Caused by SSLError(SSLError(9,'[SSL] PEM lib (_ssl.c:3932)')))

那么我还需要从窗口的证书存储中提取什么来传递客户端证书？

解决方法

我认为您可能在 urllib3 上遇到了错误，请尝试将其更新到最新版本：
