Briefcase: Need for manual install of unlimited-strength JCE is a support headache #667

What steps will reproduce the problem?
1. Create and use an encrypted form as per the instructions.
2. Install Briefcase.
3. Download and attempt to decrypt encrypted submissions.

What is the expected output? What do you see instead?

You expect decryption to work. Instead, in the vast majority of cases, it gives 
an "illegal key size" error. This is because the user's JRE installation needs 
to be manually upgraded with the Java Cryptography Extension (JCE) Unlimited 
Strength Jurisdiction Policy Files. This is a serious pain.

Would be nice for Briefcase to have an installer that automates or at least 
semi-automates installation of the necessary files. Alternatively, might 
default to weaker encryption and allow users to specify stronger encryption 
once their JRE's have been upgraded. (As it stands, users in export-restricted 
countries can never use ODK encryption unless an option for weaker encryption 
is allowed.)

Needs a full ODK team discussion to decide.
