将证书链添加到p12（pfx）证书

Question

我在java和cxf中有一个用客户端证书连接到WebServices的应用程序。

我从WebService所有者那里获得了证书

• 证书
• 证书
• certificate.crt
• Trusted_ca.cer
• root_ca.cer

我直接将这个p12证书转换为java要求的有效jks密钥库时遇到问题。

我这样做：

keytool -importkeystore -srckeystore certificate.p12 -srcstoretype PKCS12 -destkeystore certificate1.jks -deststoretype JKS -storepass secret
keytool -import -alias root -file root_ca.cer -trustcacerts -keystore certificate1.jks -storepass secret
keytool -import -alias trusted -file trusted_ca.cer -trustcacerts -keystore certificate1.jks -storepass secret

但是此jks不起作用，使用此证书时我收到HTTP响应‘403：Forbidden’

但是，如果我将此p12（pfx）证书导入Internet
Explorer，然后将此证书从IE导出为pfx格式，请选中“在证书路径中包括所有证书”复选框，并使用：

keytool -importkeystore -srckeystore certificate.pfx -srcstoretype PKCS12 -destkeystore certificate2.jks -deststoretype JKS -storepass secret
keytool -import -alias root -file root_ca_kir.cer -trustcacerts -keystore certificate2.jks -storepass secret
keytool -import -alias trusted -file trusted_ca_kir.cer -trustcacerts -keystore certificate2.jks -storepass secret

然后，一切正常，我可以使用certificate2.jks连接到WebService。

我发现原始的certificate.p12（pfx）仅包含一个条目（证书链长度：1）：

keytool -list -keystore certificate.p12 -storepass secret -storetype PKCS12 -v

从IE导出的带有“在证书路径中包括所有证书”的certificate.pfx包含带有第二个受信任CA证书的证书链（证书链长度：2）：

keytool -list -keystore certificate.p12 -storepass secret -storetype PKCS12 -v

因此，要解决我的问题，我需要拥有带有可信任CA证书链的p12证书。我可以通过将p12导入IE，然后通过“在证书路径中包括所有证书”将其导出回来来实现。

不使用IE使用keytool或其他工具怎么办？

自己回答。

我想出了如何使用OpenSSL做到这一点：

openssl pkcs12 -in certificate.p12 -out clientcert.pem -nodes -clcerts
openssl x509 -in trusted_ca.cer -inform DER -out trusted_ca.pem
openssl x509 -in root_ca.cer -inform DER -out root_ca.pem
cat clientcert.pem trusted_ca.pem root_ca.pem >> clientcertchain.pem
openssl pkcs12 -export -in clientcertchain.pem -out clientcertchain.pfx
