使用代理的openssl s_client


openssl s_client using a proxy

1
openssl s_client -connect some.https.server:443 -showcerts

当您要检查服务器的证书及其证书链时，这是一个很好的命令。

当您位于HTTP / HTTPS代理后面时，是否可以运行此命令？

您可以使用proxytunnel：

1
proxytunnel -p yourproxy:8080 -d www.google.com:443 -a 7000

然后您可以执行以下操作：

1
openssl s_client -connect localhost:7000 -showcerts

希望这可以帮到你！

即使使用openssl v1.1.0，我在传递代理时也遇到一些问题，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：

您可以在启用Java SSL日志记录的情况下运行它

这应该产生不错的输出，例如
