How to attach information to a TCPSocket for the OpenSSL context later on

mypki-xpe.rb

require 'socket'

class TCPSocket
    class << self 
        def new host, *args, &block
            socket = super host, *args, &block
            # check whitelist, set indicator
            socket.instance_variable_set :@mypki, true # or false
            # return socket
            socket
        end

        alias :open :new
    end
end

require 'openssl'

class OpenSSL::SSL::SSLSocket
    class << self
        def new io, ctx = nil
            if io.is_a? TCPSocket
                # check indicator, and swap context appropriately
                puts io.instance_variable_get(:@mypki)
            end

            super io, ctx
        end
    end
end
