Gem CoDTLS

Ruby Gem for RFC XXXX - CoDTLS: DTLS handshakes over CoAP

WORK IN PROGRESS - ITS NOT SECURE - THERE IS MANY WORK TO DO

This gem is an implementation of CoDTLS. CoDTLS is a protocol, which utlilizes CoAP and CoAP ressources for DTLS. See http://www.ietf.org/internet-drafts/draft-schmertmann-dice-codtls-00.txt for further details.

Add this line to your application's Gemfile:

gem 'openssl-ccm'

And then execute:

$ bundle

Or install it yourself as:

$ gem install openssl-ccm

When the gem is installed you have to call its generator to generate the needed ActiveRecord Migrations in your db/migrate folder

rails g codtls

You now have apply these migrations to your database with

rake db:migrate

Your Rails project should now be able to use this ruby gem.

You have to require the gem in the file you are using with

require 'codtls'

Now you can create a SecureSocket object and use it like any other socket.

# example for a client application
ssocket = CoDTLS::SecureSocket.new
ssocket.sendto('AAAA::1', 'Test message')
answer = ssocket.recvfrom('AAAA::1')
