See my version here: http://bibwild.wordpress.com/2009/05/18/authenticating-to-amazon-product-api-in-ruby/ I am not using ruby/aws, however. I guess ruby/aws needs to be updated to do signing; talk to the developer of that gem, or try to figure out how to do it yourself (perhaps guided by the code pointed to above). Or stop using ruby/aws and do it yourself manually using the code pointed to above. Jonathan -- Posted via http://www.ruby-forum.com/.
