我有一个PEM证书，我正在使用

查看它的内容。是否可以将输出解析为JSON格式？也许有Java库或Bash脚本可以做到这一点

命令：
$opensslx509-in sample.cer-noout-text

输出：

我能够构建一个Python脚本来完成您所需要的功能。此脚本接受一个参数，
，并返回包含此内容的JSON对象

$ ./pem2json.py <PEM FILE>
代码 调试输出 工具书类
我一直在寻找这一点，并在服务器上运行了大量PHP脚本

@slm的答案可能很好，但这里有一个内置的PHP函数，它可以做您想要的事情

这是我自己的python脚本（源自上面的脚本）

它还可以接受具有多个证书的PEM

#!/usr/bin/env python3

def main():
    cert_file_name = sys.argv[1]
    try:
        pems = pem.parse_file(cert_file_name)
    except Exception as e:
        print(f"Error decoding pem: {e}\n")
        sys.exit(1)

    res = []
    for p in pems:
        f = tempfile.NamedTemporaryFile(mode='w', delete=False)
        f.write(p.as_text())
        f.close()

        try:
            cert = ssl._ssl._test_decode_cert(f.name)
            # remap array mess in subject and issuer into dicts

                    for s in cert[item]:
                        for i in s:
                            if i[0] not in item_dict:

    exit 12

read-r-d''JSON的用途是什么？你的目标是什么？在bash中无法做到这一点。您必须使用不同的实用程序。
