Java 密钥库更改密码

Keystore change passwords

提问by user313724

I currently have a keystore, with a particular password that only I should know. I now need to give access to that keystore to someone else, so I would like to either:

我目前有一个密钥库，有一个只有我应该知道的特定密码。我现在需要将该密钥库的访问权限授予其他人，因此我想：

1) Change the password, so I can share it with others and let them sign
2) Create a different password and allow them to sign with it.

1) 更改密码，以便我可以与他人共享并让他们签名
2) 创建一个不同的密码并允许他们使用它进行签名。

Is this possible? and - if yes - how?

这可能吗？和 - 如果是 - 如何？

**Keystorename**: name of your keystore(with path if you are indifferent folder)

for example: $keytool -keypasswd -keystore keystorename -alias stop\ watch

If the keystore contains other key-entries with different password you have to change them also or you can isolate your key to different keystore using below command,

如果密钥库包含其他具有不同密码的密钥条目，您也必须更改它们，或者您可以使用以下命令将您的密钥隔离到不同的密钥库，

keytool -importkeystore  -srckeystore mystore.jck -destkeystore myotherstore.jks -srcstoretype jceks
-deststoretype jks -srcstorepass mystorepass -deststorepass myotherstorepass -srcalias myserverkey
-destalias myotherserverkey -srckeypass mykeypass -destkeypass myotherkeypass

For a full programmatic change (e.g. install program) and no prompting

对于完整的程序更改（例如安装程序）并且没有提示

#!/bin/bash -eu

NEWPASSWORD=
OLDPASSWORD=

keytool -storepasswd -new "${NEWPASSWORD}" \
  -storepass "${OLDPASSWORD}" \
  -keystore /path/to/keystore

Full disclosure: I DO NOT recommend running this command line in a shell, as the old and new passwords will be saved in the shell's history, and visible in console.

完全披露：我不建议在 shell 中运行此命令行，因为旧密码和新密码将保存在 shell 的历史记录中，并在控制台中可见。
