+If you run into javax.crypto.JceSecurity errors, do the following:

+1. Add the BouncyCastle Provider to your JRE/JDK, per instructions at http://www.bouncycastle.org/wiki/display/JA1/Provider+Installation/
+
+2. Download the "Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files" for your JRE version from http://www.oracle.com/technetwork/java/javase/downloads/index.html (scroll to the bottom of the page).
+
+3. Install the new policy files per the README file included in the download. The download contains new versions of local_policy.jar and US_export_policy.jar. These files must be placed in your jre/lib/security folder(s - multiple on Windows), replacing the current files. If you wish to at some point revert back to your original policy files, store the original files elsewhere.
