Java keytool从url / port添加服务器证书的简便方法 [英] Java keytool easy way to add server cert from url/port

问题描述

我有一个带有自签名证书的服务器，但也需要客户端证书身份验证。我正在尝试获取原始CA服务器证书，因此我可以将其导入密钥库。任何人都有一些关于如何轻松做到这一点的建议？谢谢。

I have a server with a self signed certificate, but also requires client side cert authentication. I am having a rough time trying to get the raw CA server cert so I can import it into a keystore. Anyone have some suggestions on how to easily do that? Thanks.

推荐答案

正在研究如何在使用jenkins cli时信任证书，并发现
https://issues.jenkins-ci.org/browse/JENKINS-12629 ，其中有一些食谱。

Was looking at how to trust a certificate while using jenkins cli, and found https://issues.jenkins-ci.org/browse/JENKINS-12629 which has some recipe for that.

这将为您提供证书：

openssl s_client -connect ${HOST}:${PORT} </dev/null

如果您只对证书感兴趣部分，通过管道将其切割成：

if you are interested only in the certificate part, cut it out by piping it to:

| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

并重定向到文件：

> ${HOST}.cert

然后使用keytool导入它：

Then import it using keytool:

keytool -import -noprompt -trustcacerts -alias ${HOST} -file ${HOST}.cert \
    -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}

一气呵成：

HOST=myhost.example.com
PORT=443
KEYSTOREFILE=dest_keystore
KEYSTOREPASS=changeme

# get the SSL certificate
openssl s_client -connect ${HOST}:${PORT} </dev/null \
    | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert

# create a keystore and import certificate
keytool -import -noprompt -trustcacerts \
    -alias ${HOST} -file ${HOST}.cert \
    -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}

# verify we've got it.
keytool -list -v -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS} -alias ${HOST}
