How to implement custom authentication logic in ASP .NET MVC 5?

Question

ASP.NET

Good afternoon! Recently started learning ASP .NET MVC5 WEB API. What the studio itself generates is not to be liked and is not needed. I googled but did not find a Russian-language normal description (I am lame with English, yes, yes, yes, I need to learn).
And so I want to do it:
For each user, a token (of openings) and a key (of closings) are issued upon registration. The token will be stored on the server in clear text. The key is in the form of a hash.
The client, using the token, composes a request in the following form:
/api/{token}/persons/{id}
In the request header, passes the hash created using the key and the query string in a certain order.
The server identifies the user by the token and also generates a hash from the query string using the user's key.
How can you implement what to read?

Answer 1

Dig around here and here .

Answer 2

It is better to pass the token in the HTTP header, and sap.net webapi has an implementation of Bearer authorization
