to_s

        # OpenSSL::Config.to_s

(from ruby core)
### Implementation from Config
---
    config.to_s -> string

---

Gets the parsable form of the current configuration.

Given the following configuration being created:

    config = OpenSSL::Config.new
      #=> #<OpenSSL::Config sections=[]>
    config['default'] = {"foo"=>"bar","baz"=>"buz"}
      #=> {"foo"=>"bar", "baz"=>"buz"}
    puts config.to_s
      #=> [ default ]
      #   foo=bar
      #   baz=buz

You can parse get the serialized configuration using #to_s and then
parse it later:

    serialized_config = config.to_s
    # much later...
    new_config = OpenSSL::Config.parse(serialized_config)
      #=> #<OpenSSL::Config sections=["default"]>
    puts new_config
      #=> [ default ]
          foo=bar
          baz=buz
