SSO Ruby code fails
The SSO Ruby code sample fails in my environment. Using the sample script accessible via the Ruby link on Ruby 1.9.3 yields the following:
irb(main):028:0* 16.times { |i| message_json[i] ^= iv[i] }
NoMethodError: undefined method `^' for "{":String
from (irb):28:in `block in irb_binding'
from (irb):28:in `times'
