Java http(s) 客户端没有失败

Question

我有一个使用 Apache HTTP components 的 Java SE 桌面(控制台)应用程序图书馆:

<dependency org="org.apache.httpcomponents" name="httpcore" rev="4.4.5"/>

在最底层，我只是在做一个:

CloseableHttpClient httpClient = HttpClients.custom().setDefaultHeaders(headers).build();
CloseableHttpResponse response = httpClient.execute(request); 

然后我使用此控制台应用程序访问通过 SSL 提供的 Web 服务，并且服务器配置了以下证书:

Common Name (CN)    InCommon RSA Server CA
Organization (O)    Internet2
Organizational Unit (OU)    InCommon

我原以为我的客户会失败。这是因为当我查看与 Java 捆绑在一起的证书时，其中似乎没有任何带有“internet2”或“inc”的证书:

$ keytool -keystore /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts -list | grep -i 'internet2\|inc'
Enter keystore password:  
<no output>
$

为什么我的客户没有失败？我没有将其配置为接受所有证书。在过去(当服务器根本没有提供证书时)代码确实失败了，但我期望使用新证书情况会保持不变，因为 InCommon CA 未列在 Java 的 cacerts 中 文件。

Answer 1

使用 keytool -printcert -sslserver hostname[:port] 的建议非常有用。

我仍然不太清楚如何破译 keytool -printcert -sslserver 的输出以及如何将它与 keytool -printcert 的输出“连接”。以下(脆弱的)咒语确实找到了一些匹配项:

for x in $(keytool -printcert -sslserver example.com:443 -v | grep ^Issuer | awk '{print $2}' | cut -c4- | sort | uniq); do keytool -keystore /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts -list   | grep -i $x; done

... 然而，匹配对键不敏感且仅在前缀上。

特别是 keytool -printcert -sslserver 的输出有字符串“USERTrust”，但 keytool -keystore 的输出最接近的是:“usertrusteccca”和“usertrustrsaca”。

`keytool -printcert -sslserver` 的输出(greping for `usertrust`)

$ keytool -printcert -sslserver example.com:443 -v | grep -i usertrust
