 <p>Here's an example of a Keytool command that generates a private key:</p>
 
 <pre>$ keytool -genkey -v -keystore my-release-key.keystore 
--alias alias_name -keyalg RSA -validity 10000</pre>
+-alias alias_name -keyalg RSA -keysize 2048 -validity 10000</pre>
 
 <p>Running the example command above, Keytool prompts you to provide
