Keytool command for Raspberry Pi

Question

我正在使用Raspberry Pi（Debian 3.1.9+ armv6l linux）和javaSE 7，并且试图通过keytool更改我的trustore密码，但是keytool命令不起作用，所以请您告诉我如何在这种环境下更改我的trustore密码。 。

Answer 1

I tested with Oracle Java SE 8 for ARM and it worked without any problems. First, create a keystore if you have not done that:

keytool -genkey -keyalg rsa -alias tstkey

Once the keystore is setup, you can change the password using

keytool -storepasswd

If you see the following error message when changing the password, it means that the keystore has not been created before, and you have to use keytool -genkey ... to create it:

pi@raspberrypi ~ $ keytool -storepasswd
keytool error: java.lang.Exception: Keystore file does not exist: /home/pi/.keystore
