If you got following error,
OpenSSL::Cipher::CipherError (Illegal key size)
it means you need to install ‘Java Jurisdiction policy files’. These files can be downloaded from http://www.oracle.com/technetwork/java/javase/downloads/jce-6-download-429243.html and copy ‘local_policy.jar’, ‘US_export_policy.jar’ and replaced at ‘C:\Program Files\Java\jdk1.6.0\jre\lib\security’.
