tomcat 不提供中间证书(https) [英] tomcat doesn't deliver intermediate certificate (https)

问题描述

我使用 openssl 可执行文件在控制台上创建了一个密钥和一个 csr.然后我将 csr 发送到 CA 并取回证书.现在我想把它导入到tomcat中.

I created a key and a csr on console, using the openssl executable. Then I sent the csr to a CA and got the certificate back. Now I want to import it into tomcat.

所以我用我的密钥和证书创建了一个 PKCS#12 文件:

So I created a PKCS#12 file out of my key and my certificate:

openssl pkcs12 -export -in mycert.cert -inkey mykey.pem -out key_and_cert.p12

然后创建一个包含它的密钥库:

and then created a keystore containing it:

keytool -importkeystore -deststorepass [password] -destkeystore keystore.jks -srckeystore key_and_cert.p12 -srcstoretype PKCS12 -srcstorepass [password]

然后我导入中间证书chain.crt:

Then I import the intermediate certificate chain.crt:

keytool -import -trustcacerts -alias root -file chain.crt -keystore keystore.jks

这里是keytool -keystore keystore.jks -list"的输出:

Here the output of "keytool -keystore keystore.jks -list":

Keystore-Typ: JKS
Keystore-Provider: SUN

Ihr Keystore enthält 2 Einträge.

root, 14.11.2011, trustedCertEntry,
Zertifikatsfingerabdruck (MD5): [fingerprint]
1, 14.11.2011, PrivateKeyEntry, 
Zertifikatsfingerabdruck (MD5): [fingerprint]

tomcat server.xml 包含:

The tomcat server.xml contains:

<Connector port="443" protocol="HTTP/1.1" SSLEnabled="true"
           maxThreads="150" scheme="https" secure="true"
           clientAuth="false" URIEncoding="UTF-8" compression="on"
           sslProtocol="TLS"
           keystoreFile="/[absolute-path]/keystore.jks"
           keystorePass="[password]" />

当我重新启动 tomcat 时，它在 catalina.out 中没有记录任何错误，一切似乎都很好.但是当我运行Firefox时，它会报告

When I restart tomcat, it logs no errors in catalina.out, everything seems to be ok. But when I run firefox, it reports

[domain] uses an invalid security certificate.
The certificate is not trusted because no issuer chain was provided.
(Error code: sec_error_unknown_issuer)

运行openssl s_client -connect [domain]:443 -showcerts"返回

Running "openssl s_client -connect [domain]:443 -showcerts" returns

我认为虽然tomcat知道中间证书，但它不会提供中间证书.怎么做才能让tomcat投递呢?

I think tomcat doesn't deliver the intermediate certificate although it knows it. What can I do to make tomcat deliver it?

附加信息:导入 pkcs12 证书时，没有证书链错误，因为 -importkeystore 命令不检查链.我也试过先导入中间证书，然后调用-importkeystore.我得到了同样的结果.

Additional information: When importing the pkcs12 certificate, there is no certificate chain error, because the -importkeystore command doesn't checks the chain. I also tried to import the intermediate certificate first and then call -importkeystore. I got the same results.

我刚刚尝试了另一种方式，将链直接插入到 PKCS#12 证书中，并得到以下错误:

edit: I just tried another way by inserting the chain directly in the PKCS#12 certificate and get the following error:

$ openssl pkcs12 -export -CAfile chain.pem -in mycert.cert -inkey mykey.pem -out key_and_cert.p12 -name tomcat -chain
Error unable to get issuer certificate getting chain.

但是链证还可以:

$ openssl verify chain.pem
chain.pem: OK

推荐答案

终于搞定了.这不是一个干净的解决方案，但它有效.我将中间证书添加到我的本地/etc/ssl/certs 然后调用

Finally I got it working. It's not a clean solution, but it works. I added the intermediate certificate to my local /etc/ssl/certs and then called

openssl pkcs12 -export -in cert.pem -inkey key.key -out key_and_cert.p12 -chain

生成的 pkcs12 证书我通过以下方式转换为 jks

The resulting pkcs12 certificate I converted to jks via

keytool -importkeystore -deststorepass [password] -destkeystore keystore.jks -srckeystore key_and_cert.p12 -srcstoretype PKCS12 -srcstorepass [password]

这个生成的文件现在似乎可以工作了，tomcat 也将证书链传递给在/etc/ssl/certs 目录中没有中间证书的客户端.但我认为也必须有一种不改变/etc/ssl/certs 的方法.

This resulting file seems to work now, tomcat delivers the certificate chain also to clients that don't have the intermediate certificate in their /etc/ssl/certs directory. But I think there must also be a way without changing /etc/ssl/certs.
