  JWT password validation question

  Mar 03, 2019 06:09 PM|cenk1536|LINK

  Hello guys,

  I have an asp.net web API. I implemented a token authentication that I am trying to validate user name and password from the database. I am new to JWT so I need your advice.

  Here are my questions;

  1. Should I encrypt username and password in my database?
  2. The client sends the username and password in the request body, Should the client send them in the header? And should they be encrypted?

  Best Regards.

  I recommend that you set aside time to learn standard practices which you can learn by going through many of the tutorials in this site.  Also learn JWT.

  1. Should I encrypt username and password in my database?

  No.  Passwords are hashed and username are stored in plain text.

  2. The client sends the username and password in the request body, Should the client send them in the header?

  Commonly username and password are submitted in the HTTP message body.

  And should they be encrypted?

  Yes, always use TLS (HTTPS).

  Is there any asp.net web api 2 tutorial about storing hash+salt on DB and comparing user password by hashing with salt?

  Yes, there are many examples that you can find by doing a basic internet search. 

  https://docs.microsoft.com/en-us/aspnet/core/security/data-protection/consumer-apis/password-hashing?view=aspnetcore-2.2

  I recommend using the APIs that come with ASP.NET like Identity rather than rolling your own.
