I have a simple rails app that is interacting with a payment processing service. I am looking to validate a https callback and all I am given is a SHA1 in order to do so. Is it possible to verify the remote identity with this SHA1 string alone? I have looked at some openssl code samples and I am not quite sure how to do this? Do I need to put this SHA1 in a file and read it in? Do I need to obtain the cert of the payment processor and put a copy on my server? Anyone got any snippets? thanks -- You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.
