With this post I want to begin a series of posts about general algorithms. It is not an accident I started with the prime numbers. This is basic problem to solve when you are starting with programming. And one more reason – I was curious how RSA algorithm works and the important part of the algorithm is to generate two random big prime numbers.
I am working for a Start Up project – DiagramArt, where we needed to create Android application which : load list of diagrams from API, show these diagrams to the user and some other stuff of course. The list consists from a preview picture, diagram’s title and its description. There is no problem to load and show these data, the problem was in the preview picture.
Few weeks ago in the late night, my friend asked me, where do I take the energy. He knows I have work, couple of sides projects and from time to time I try to write here some post. Is it some kind of a coffee? Or something else? I didn’t know how to answer, but I was thinking about it during a walk.
I needed to create a simple server, that would have one “public” route
/login and other routes are available only for users with valid JWT token.
That means, the user is allowed to log into the system and then get any data from it. If he is not logged in and he tries to get some data, he only get an error message and 401 ( Unauthorized ) status code will be returned.
