尝试刷新'过期'密钥库 [英] Trying to refresh 'expired' keystore

问题描述

我试图重新签订使用Ant任务signjar但它告诉我一些罐子签名证书已过期。

I am trying to re-sign some jars using the ant task 'signjar' however it's telling me "The signer certificate has expired."

于是，我就重新生成密钥库希望这会未过期这...

So I tried to re-generate the keystore hoping this would 'un-expire' it...

的keytool -genkey -keystore mykeystore -alias myalias

但进入存储密码，我收到后的keytool错误：java.lang.Exception的：密钥对未生成，别名已存在

but after entering the keystore password i get: "keytool error: java.lang.Exception: Key pair not generated, alias already exists"

我在做什么错了？我是否需要删除密钥库重新生成它还是有一个简单的方法来刷新它，所以它没有过期？

what am i doing wrong? do i need to delete the keystore to re-generate it or is there a simple way to refresh it so it's not expired?

感谢。

推荐答案

你混淆的术语。密钥库包含键，一键是用于签名的东西。

You're mixing up the terms. A keystore contains keys, a key is something used for signing.

据我所知，你试图把新钥匙插入使用现有的别名（名称）的旧密钥库。你为什么不干脆用一个新的？这个或删除从旧密钥密钥存储第一。你并不需要删除整个密钥库。

AFAIK, you're trying to put a new key into an old keystore using an existing alias (name). Why don't you simply used a new one? Either this or delete the old key from the keystore first. You don't need to drop the whole keystore.
