How to set default language for java keytool?

Question

I use Windows OS with English language and US keyboard setting. I use this command to generate keystore. It works fine.

C:\java6\jre\bin\keytool -genkey -keyalg RSA -alias mykey -validity 3652 -keystore C:\mykeystore -storepass 111111111 < data.txt

The data.txt

My name
My org unit
My org
My city
My state
ch
yes

However, this program cannot work normally on Windows with German language and keyboard setting. I must change the word "yes"" to "ja" in data.txt to make it works.

It isn't good to modify the data.txt.

Is there any way to set English as default language for keytool?

I found out that we can force Java to use English as default language by adding `-J"-Duser.language=en"` — Tuan, Aug 14 '13 at 10:45

In a nutshell you must pass the -Duser.language=en option to the Java machine. I know of two ways to do this:

For just one invocation, specify the -J-Duser.language=en option on the keytool command line, e.g.
```
keytool -J-Duser.language=en -genkey -keyalg RSA -alias mykey -validity 3652 -keystore C:\mykeystore -storepass 111111111 < data.txt
```

To change Java language globally, set the JAVA_TOOL_OPTIONS environment variable to have the -Duser.language=en value.

Thanks, I found it :) – Tuan Jun 25 '14 at 03:11
The `-J-Duser.language=en` parameter does not seem to be understood by keytool.exe on Windows. The approach via `JAVA_TOOL_OPTIONS` however works fine. – Tomalak Oct 05 '16 at 15:08
