# sshlogin

POC for application login using ssh keys

client and server code to demonstrate using ssh keys for login

# Steps:

### Registration

    a. client registers with server by calling register endpoint with username and ssh publickey

    b. server stores user data (a simple map for POC only)

### Login

   a. client signs a string and calls login endpoint with string, ssh signature, and username

   b. server verifies signature and returns session cookie

### Application Enpoints

  a. client includes session cookie for calls to application endpoints
