  === Source Code
  
  _buddy-sign_ is open source and can be found on link:https://github.com/funcool/buddy-sign[github].
  
  You can clone the public repository with this command:
  
  
negative.code: ;; wait 5 seconds and try unsign it
  
  (jwe/decrypt token secret)
  ;; => ExceptionInfo "Token is older than :exp (1427836475)"

  === Asymetric encryption schemes
  
  In order to use any asymetric encryption algorithm, you should have private/public
  key pair. If you don't have one, don't worry, it is very easy to generate it
  using *openssl*, see this <<generate-keypairs,faq entry>>.
  
  Then, having ready the key pair, you can strart using one of the supported
  key encryption algorithm in the JWE specification such as `:rsa1_5`, `:rsa-oaep`
  or `:rsa-oaep-256`.
  
  Let see an demostration example:
