keytool error Keystore was tampered with or password was incorrect

Question

When I generate certificates on my local machine I end up getting this error:

C:\Users\abc>keytool -genkey -alias tomcat -keyalg RSA
Enter keystore password:
keytool error: java.io.IOException: Keystore was tampered with, or password was incorrect

What is the problem here? This works fine on other machines but throws this error in my device.  

Answer 1

The error occurred because you are not specifying an explicit Keystore so it will try to generate Keystore C:\users\abc>.keystore and you need to provide the old password for .keystore but I think you are giving a new password.

To solve this, you can delete .keystore from C:\users\abc>  and then try the command. Or you can just try the following command which will create a new xyzkeystore:

keytool -genkey -keystore xyzkeystore -alias tomcat -keyalg RSA

I hope this helps you.
