Question

我有带有CTL证书的数据库（使用“ certstream”实用程序）。一种证书数据的示例：

{
"all_domains" : [ 
    "benesseresalus.com", 
    "benesseresalus.it",

我想使用代码了解此证书是否有效。

我搜索并看到了pyopenssl的许多用法：https://pyopenssl.org/en/stable/api/crypto.html#revoked-objects

但是所有用法都要求我拥有.pem文件。我想我可以通过打开一个新文件来创建.cert文件，如下所示：

 ----BEGIN CERTIFICATE----

-----END CERTIFICATE-----

但是我仍然会缺少.pem文件。

底线：我想使用提供的json数据，并且知道此证书是否被吊销。请告诉我我所缺少的。

我需要python代码才能执行此操作。我遇到了验证者-https://github.com/wbond/certvalidator 并运行以下代码：

context = ValidationContext(allow_fetching=True)
validator = CertificateValidator(end_entity_cert, validation_context=context)

我有revocation_mode：soft-fail，据我所知没有信息。

最终编辑：感谢@Steffen Ullrich，有效的python代码：

import os
import subprocess
openssl_location = "\"C:\\Program Files\\OpenSSL-Win64\\bin\\openssl.exe\""`
for element in cursor:
        authorityInfoAccess = element['data']['leaf_cert']['extensions']['authorityInfoAccess']
        ocsp_url, crt_url = [x.strip(" ").lstrip("URI:").rstrip("\n").rstrip("\nCA Issuers") for x in authorityInfoAccess.split("-") if 'URI' in x]

        if 'ocsp' in crt_url:
            ocsp_url, crt_url = crt_url, ocsp_url

        serial_number = authorityInfoAccess = element['data']['leaf_cert']['serial_number']

        shell_convert_cmd = 'curl ' + crt_url + " > issuer.crt"
        os.system(shell_convert_cmd)

        to_pem_cmd = openssl_location + ' x509 -in issuer.crt -inform der -out issuer.pem'
        os.system(to_pem_cmd)

        request_cmd = 'ocsp -issuer issuer.pem -serial 0x' + serial_number + ' -url ' + ocsp_url
        full_cmd = openssl_location + " " + request_cmd
        out = subprocess.check_output(full_cmd, shell=True)
        print (f"program output: {str(out)}")

如何检查是否使用Python吊销了证书日志中的证书（不在PC上）？
