How Http Basic Authentication Industrial Plant Inwards Jump Security?

In the terminal article, you lot accept learned how to enable Http basic authentication inwards Spring security based Java application as well as straight off we'll become 1 measuring farther to empathize how just http basic authentication plant inwards Spring security. If you lot remember, when you lot exercise HTTP Basic for authentication role the customer e.g. browser or a residuum customer sends login credentials inwards http asking header. The header is aptly named every bit "Authorization" as well as it contains based 64 encoded string which is created past times concatenating username as well as password using a colon. For example, if the username is "johnsmith" as well as password is "JOHN3214" so they volition travel concatenated every bit "johnsmith:JOHN3214" earlier encoded using base of operations 64 encoding algorithms.

The server, when receives such request, it extracts the value of "Authorization" header as well as decodes the content of this header using the same algorithm Base64 for authenticating the user.

If you lot remember, nosotros used <http-basic>l; inwards XML configuration or httpBasic() method on HttpSecurity object to enable basic authentication.

Now, let's run across how just Spring safety supports Http Basic Authentication as well as how things motility within Spring safety infinite when it receives a login asking as well as Http basic authentication is enabled at the server end.



How Spring Security Process Http Basic Authentication Requests

When you lot exercise the <http-basic>l; configuration element, Spring Security's BasicAuthenticationFitler comes into the picture, which basically checks if incoming HTTP request contains the "Authorization" header or non as well as its value starts alongside "Basic".

Influenza A virus subtype H5N1 BasicAuthenticationEntryPoint strategy is besides configured into the ExceptionTranslationFilter on startup, which is required to handgrip asking doesn't incorporate "Authorization" header.

When you lot brand an http asking to a protected URL e.g. /admin/users from the browser without adding "Authorization" header so Spring Security throws an access-denied exception that is handled past times the ExceptionTranslationFilter.

This filter so delegates to a item implementation strategy of AuthenticationEntryPoint interface, which is the BaicAuthenticationEntryPoint inwards our case.

This flat adds the header "WWW-Authenticate: Basic real="Spring Security Application" to the reply as well as so sends an HTTP condition code of 401 (Unauthorized) to the customer e.g. to your browser, which knows how to handgrip this code as well as travel accordingly i.e. it shows a dialog box prompting for username as well as password, similar below:

When you lot position the username as well as password as well as submit the request, the asking in 1 lawsuit again follows the filter chain until it reaches the BasicAuthenticationFilter.

This filter checks the asking headers, place for the Authorization header starting alongside "Basic" e.g. Authorization: Basic CDWhZGRpbjpvcGVuc2AzYW1l.

The BaicAuthentictionFilter so extracts the content of the "Authorization" header as well as uses Base64 algorithm to decode the login credentials to extracts the username as well as password from decoded String.

Once it has that information, the filter creates a UsernamePasswordAuthenticationToken object as well as sends it to the authentication managing director for authentication inwards the criterion way.

If you lot don't know the role of AuthenticationManager on saltation safety login, then, you lot tin acquire to a greater extent than nigh that inwards Eugen's Learn Spring Security Course.


The authentication managing director volition inquire the authentication provider (e.g. inwards memory, JDBC backed or LDAP based) to retrieve the user as well as so practise an Authentication object alongside it. This procedure is criterion as well as independent of using HTTP basic for authentication e.g. applicable for digest authentication every bit well.

If you lot are working inwards RESTful spider web services, you lot tin besides exercise curl command to ship HTTP asking alongside "Authorization" mistake for HTTP basic authentication. I accept institute curl an slow agency to examine spider web services past times sending diverse HTTP ascendency from ascendency line.

 You tin besides run across my post service how to examine RESTful spider web services to uncovering out around practical examples of curl e.g. sending post service request, sending a asking alongside HTTP basic as well as Digest authentication etc.

Btw, every bit I accept said before, basic authentication is non secure, anyone who tin intercept the asking tin decode the password, thence it is alone used for testing purpose, piece to a greater extent than sophisticated digest authentication as well as OAuth is used inwards the real-world application, especially if you lot are desire to secure your REST API.

I'll say you lot to a greater extent than nigh securing REST API inwards coming articles merely if you lot can't wait, I propose you lot banking venture fit out REST alongside Spring MasterClass which is lately updated for Spring Framework v as well as Spring Security v every bit well.

That's all nigh how does HTTP basic authentication plant within Spring Security. You accept seen the sum workflow of what happens when an HTTP asking hits a protected URL which requests basic authentication. It's basically the BasicAuthenticationFilter which does most of the undertaking along alongside BasicAuthenticationEntryPoint.
