Foi implementando no DA20 a funcionalidade de criptografia dos dados transmitidos. Todos os dados (tudo que se trafega nas aplicações DA20) transmitidos são criptografados onde somente o servidor sabe recuperar os dados.
O processo mostrado abaixo é uma rotina para salvar dados de um usuário no servidor.
