how to distribute Java apps with unlimited strength cryptography?

I am making an app that uses unlimited strength cryptography (larger keys, etc). For my development, I needed to modify the JDK in order to use these as described here and here.

What are my options for distributing the app? One method is to distrib开发者_JS百科ute a custom JRE with the modified policy files.

In general, users will be running other cryptographic applications in their JRE. They may already have a suitable JRE. As a user, I wouldn't want to install a new copy just for your application.

I'd suggest giving them instructions to install the unlimited strength jurisdiction files, or creating a tool to install them, rather than trying to distribute an entire JRE.
