将.cer证书转换为.jks [英] Convert .cer certificate to .jks

问题描述

我需要将 .cer 文件转换为 .jks 文件。
我看到了一些关于它的问题，但没有看到我需要的解决方案。

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.

我不需要它来添加它到我的本地证书，但作为上传到服务器的文件。
我还需要只做一次，而不是以编程方式。
这个帖子有使用java将.cer转换为.jks 和作者说他已经成功完成了，但由于我没有足够的声誉，我无法对他的上一次回复发表评论，也不能向他发送个人信息并问他。

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.

所以，如果有人知道一个简单的方法，我会很高兴听到。

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

推荐答案

JDK安装附带 keytool （在 bin 文件夹中）：

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

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

这将创建一个新的密钥库并仅向其添加证书。

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

因此，您无法将证书转换为密钥库：您将证书添加到密钥库。

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