将密钥库密码从无密码更改为非空白密码 [英] Change keystore password from no password to a non blank password

问题描述

我有一个jks密钥库，没有密码.当我运行命令

I have a jks keystore with no password. When I run the command

keytool -list -keystore mykeystore.jks

它提示我输入密钥库密码，我只需按"enter"(输入).

And it prompts me for the keystore password, I simply hit 'enter'.

请注意，密钥库密码不是默认的Java密码"changeit".它是空白的

Please note that the keystore password IS NOT the default java password of 'changeit'. It is blank

当我尝试跑步时

keytool -storepasswd -keystore mykeystore.jks

将密码更改为非空白字符串.它首先提示我输入当前密码.只需按Enter键即可，因为它为空

to change the password to a non blank string. It firsts prompts me for the current password. Simply hitting enter since it is blank says

keytool -storepasswd -keystore mykeystore.jks
Enter keystore password:
Keystore password is too short - must be at least 6 characters 

只需要与所有人确认密码不是'changeit'

Just to confirm with everyone that the password is not 'changeit'

keytool -storepasswd -keystore mykeystore.jks
Enter keystore password:  changeit
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

您知道在现有密码为空的情况下如何更改密钥库密码吗?

Any idea how I can change the keystore password if the existing password is blank?

推荐答案

在keytool参数中添加-storepass.

Add -storepass to keytool arguments.

keytool -storepasswd -storepass '' -keystore mykeystore.jks

但还要注意，-list命令并不总是需要密码.在两种情况下，我都可以执行follow命令:不使用密码或使用有效密码

But also notice that -list command does not always require a password. I could execute follow command in both cases: without password or with valid password

$JAVA_HOME/bin/keytool -list -keystore $JAVA_HOME/jre/lib/security/cacerts
