Hi All,

Thanks for your support :-)

I just figured out that OpenSSL does not come with Ruby (at least for me), 
because I work on Windows. And the Windows release obviously does not 
contain OpenSSL.

Do you have any further help for me on how to get OpenSSL running in Ruby 
using Windows ?

>> require 'openssl'
>> def hmac(key, msg)
>>   OpenSSL::HMAC.hexdigest(OpenSSL::Digest::Digest.new('md5'), key, msg) 
end

This example is great !

I need to get it working under Windows.....

Best,
Ernst
