Welcome to the SecureSignedMailService wiki!

The objective of this project is to show how we go about developing a secure system which protects its data and users.

We shall use C++, CMake, GTest and openssl to do this.

Interfaces

1. User.h static bool createUser(std::string& name, std::string &password); // Create a user with the specified name bool deleteUser(); static bool login(std::string &name, std::string &password); bool logout();

2. Cli.h // provides a user interface using commandline with following commands

   • help- shows how to use this application
   • verify-app - verfies the signature of the app
   • signup
   • login

   below options are available when logged in

   • logout
   • delete-account
   • show-users - list all users of app
   • send-msg - send a secure message to specified user
   • read-inbox - read all incoming messages.
   • show-sent-msgs - show all messages that were sent.

Example:

gandalf $ ./ssms
