问题
I have created a Keystore using:
keytool -genkey -keystore myKeyStore -alias myself
and the password i have given is in Japanese i.e. "myPasswordは" I am using the following code to load the keystore file
String KEYSTORE_FILE="C:/myKeyStore";//Path to the keystore file on disk.
PASSWORD="myPasswordは";//Password
KeyStore.getInstance("JKS").load(new FileInputStream(KEYSTORE_FILE),PASSWORD.toCharArray());
The above throws the following exception: java.io.IOException: Keystore was tampered with, or password was incorrect.
If i create the keystore using an english password and use the same in code then it works fine.
Initially I created the keystore using the command: keytool -genkey -keystore myKeyStore -alias mks this will prompt me for the password which i enter as myPasswordは and then i enter the subsequent details. In this case, the code generates the above exception.
The interesting thing is that if i create the keystore using : keytool -genkey -keystore myKeyStore -alias mks -storepass myPasswordは then the code that i have given above works fine. I am using linux.

Well, from the description I guess that console doesn't process unicode characters as expected. You can try to use PowerShell or try to change code page of cmd.exe to UTF-8 by executing chcp 65001 command (note that this will distort console display behaviour, but it will accept input properly).

The root cause of this problem is that the keytool utility does not decode a non-ascii password entered at prompt correctly.
This is a known issue which can be found at http://bugs.sun.com/bugdatabase/view_bug.do;jsessionid=53546691146578386c644cb554976?bug_id=6433238
So, the solution is to create a keystore with a password not entered at prompt. This can be done in the following way:
keytool -genkey -keystore myKeyStore -alias myAlias -storepass すてきなパスワード
