If your ruby app is doing SSL, you have probably seen one of the following errors:
1 doc = Hpricot(open("https://www.cert.org/blogs/vuls/rss.xml")) # => /usr/lib/ruby/1.8/net/http.rb:590:in `connect': certificate verify failed (OpenSSL::SSL::SSLError)
1 warning: peer certificate won't be verified in this SSL session
The solution is to make sure ruby has access to the right set of root certificates.
The easiest way to get hold of those root certificates is by downloading this file cacert.pem (details) (updated weekly by the developers of CURL, based on the Mozilla browser). Download this file and store it somewhere in your app.
If you’re really keen on security, don’t trust the guys from CURL and download the different root certificates from their providers manually. However, in most cases, the file from CURL will suffice.
Then, in your ruby code, setup the connection like this and you’ll have a validated SSL connection:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 #! /usr/bin/env ruby require 'net/https' require 'uri' uri = URI.parse(ARGV || 'https://localhost/') http = Net::HTTP.new(uri.host, uri.port) if uri.scheme == "https" # enable SSL/TLS http.use_ssl = true # Only needed for ruby 1.8.6 # http.enable_post_connection_check = true http.verify_mode = OpenSSL::SSL::VERIFY_PEER http.ca_file = File.join(File.dirname(__FILE__), "cacert.pem") end http.start do http.request_get(uri.path) do |res| print res.body end end
