Question

openssl s_client -connect some.https.server:443 -showcerts

当您想要检查服务器的证书及其证书链时，

是一个很好的命令。

当你在HTTP / HTTPS代理后面时，有没有办法运行这个命令？

Answer 1

您可以使用proxytunnel：

proxytunnel -p yourproxy:8080 -d www.google.com:443 -a 7000

然后你可以这样做：

openssl s_client -connect localhost:7000 -showcerts

希望这可以帮到你！

Answer 2

对于2015年5月之后来到这里的人：有一个新的＆＃34; -proxy＆＃34;将包含在openssl的下一个版本中的选项：https://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest

Answer 3

官方没有。

但这是补丁http://rt.openssl.org/Ticket/Display.html?id=2651&user=guest&pass=guest

自openssl v1.1.0起

C:\openssl>openssl version
OpenSSL 1.1.0g  2 Nov 2017

Answer 5

即使使用openssl v1.1.0，我在传递代理时也遇到了一些问题，例如s_client: HTTP CONNECT failed: 400 Bad Request 那迫使我写一个最小的Java类来显示SSL握手

    public static void main(String[] args) throws IOException, URISyntaxException {
    HttpHost proxy = new HttpHost("proxy.my.company", 8080);
    DefaultProxyRoutePlanner routePlanner = new DefaultProxyRoutePlanner(proxy);
    CloseableHttpClient httpclient = HttpClients.custom()
            .setRoutePlanner(routePlanner)
            .build();
    URI uri = new URIBuilder()
            .setScheme("https")
            .setHost("www.myhost.com")
            .build();
    HttpGet httpget = new HttpGet(uri);
    httpclient.execute(httpget);
}

具有以下依赖性：

    <dependency>
        <groupId>org.apache.httpcomponents</groupId>
        <artifactId>httpclient</artifactId>
        <version>4.5.2</version>
        <type>jar</type>
    </dependency>

您可以使用Java SSL Logging turned on

运行它

这应该会产生不错的输出，例如

trustStore provider is :
init truststore
adding as trusted cert:
  Subject: CN=Equifax Secure Global eBusiness CA-1, O=Equifax Secure Inc., C=US
  Issuer:  CN=Equifax Secure Global eBusiness CA-1, O=Equifax Secure Inc., C=US
  Algorithm: RSA; Serial number: 0xc3517
  Valid from Mon Jun 21 06:00:00 CEST 1999 until Mon Jun 22 06:00:00 CEST 2020

adding as trusted cert:
  Subject: CN=SecureTrust CA, O=SecureTrust Corporation, C=US
  Issuer:  CN=SecureTrust CA, O=SecureTrust Corporation, C=US
(....)

openssl s_client使用代理
