Class HttpBasicAuthentication

java.lang.Object
  org.deegree.services.authentication.HttpBasicAuthentication

All Implemented Interfaces:

CredentialsProvider

public class HttpBasicAuthentication
extends java.lang.Object
implements CredentialsProvider

HTTP Basic Authentication.

It is a basic authentication protocol. The browser generates a dialog with the authentication credentials username and password. After typing in the needed information there is a second request needed to send the credentials back to the server. The basic authentication just encodes the username and password with a simple algorithm that is not intended to secure the credentials. In fact this encryption exists to provide multilanguage capability.
