Can you create a unique keystore file within the Unity editor?

Can you create a unique keystore file within the Unity editor
or do you need to use another program to create a keystore file?
If so where do I find the editor to create and save this file?
The JDK “KeyTool” utility is not an application I was able to open and type in.
Where do I type this code? I’m sorry. I just don’t understand. thanx

keytool -genkey -v -keystore my-release-key.keystore-alias alias_name -keyalg RSA -keysize 2048 -validity 10000

I’m trying to sign my Android game.
I appreciate any help you can give me. thanx
