我有一个带有 CA 签名证书的 JKS 密钥库。我需要以 PEM 格式导出它才能与 nginx 一起使用。我需要以包含整个链的方式进行操作,以便我的客户可以验证签名。
如果我这样做:
keytool -exportcert -keystore mykestore.jks -file mycert.crt -alias myalias
openssl x509 -out mycert.crt.pem -outform pem -in mycert.crt -inform der
它只包括最低级别的证书。验证失败:
$ openssl s_client -connect localhost:443
CONNECTED(00000003)
depth=0 /O=*.mydomain.com/OU=Domain Control Validated/CN=*.mydomain.com
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 /O=*.mydomain.com/OU=Domain Control Validated/CN=*.mydomain.com
verify error:num=27:certificate not trusted
verify return:1
depth=0 /O=*.mydomain.com/OU=Domain Control Validated/CN=*.mydomain.com
verify error:num=21:unable to verify the first certificate
verify return:1

来自Java:

而具有相同 JKS 密钥库的 Jetty 打印以下内容:
$ openssl s_client -connect localhost:8084

尽管 openssl 返回了 19 错误,但它不再是 Java 的问题HttpsURLConnection
,这就是我所关心的。
那么,如何从 JKS 导出整个链,格式(例如 PEM)同时适用于 nginx 服务器和 Java 客户端?我错过了什么?
