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
