Question

我公司有自己的ROOT证书。使用此证书，他们签署了intermediate证书。

然后我们为server证书颁发了CSR，并使用intermediate证书进行了签名。

在Java cacerts文件中导入ROOT证书和intermediate的正确方法是什么，以便能够与具有server证书签名的服务器建立SSL连接intermediate？

我使用OpenSSL测试服务器上的证书链：

openssl s_client -showcerts -connect host:443

CONNECTED(00000003)
depth=0 C = COUNTRYCODE, ST = myCountry, O = myOrganization, CN = myServer, emailAddress = myMail
verify error:num=20:unable to get local issuer certificate
verify return:1
depth=0 C = COUNTRYCODE, ST = myCountry, O = myOrganization, CN = myServer, emailAddress = myMail
verify error:num=27:certificate not trusted
verify return:1
depth=0 C = COUNTRYCODE, ST = myCountry, O = myOrganization, CN = myServer, emailAddress = myMail
verify error:num=21:unable to verify the first certificate
verify return:1

您只需要在信任库中导入根证书。

 keytool -import -trustcacerts -keystore path/to/cacerts -storepass changeit  -alias aliasName -file path/to/certificate.cer

握手期间的SSL服务器应提供证书和中间人。您的客户的TrustManager将验证证书链，直到找到root

注意：建议使用您自己的信任库而不是修改cacerts
