将 .cer 证书转换为 .jks

Convert .cer certificate to .jks(将 .cer 证书转换为 .jks)

问题描述

I need to convert a .cer file to a .jks file. I saw a few questions about it, but haven't seen a solution to what I need.

I don't need it in order to add it to my local certificates, but as a file to upload to a server. I also need to do it only once, and not programmatically. There's this thread Converting .cer to .jks using java and the author says he had done it successfully, but I couldn't comment to his last reply as I don't have enough reputation, nor could I send him a personal message and ask him.

So if anyone knows of a simple way to do so, I'll be glad to hear.

keytool comes with the JDK installation (in the bin folder):

keytool -importcert -file "your.cer" -keystore your.jks -alias "<anything>"

This will create a new keystore and add just your certificate to it.

So, you can't convert a certificate to a keystore: you add a certificate to a keystore.
