Class HttpAuthenticator

    public final class HttpAuthenticator
    extends Object
    Deprecated.
    no longer used
    Utility methods for HTTP authorization and authentication. This class provides utility methods for generating responses to HTTP www and proxy authentication challenges.
    A client SHOULD assume that all paths at or deeper than the depth of the last symbolic element in the path field of the Request-URI also are within the protection space specified by the basic realm value of the current challenge. A client MAY preemptively send the corresponding Authorization header with requests for resources in that space without receipt of another challenge from the server. Similarly, when a client sends a request to a proxy, it may reuse a userid and password in the Proxy-Authorization header field without receiving another challenge from the proxy server.

      • selectAuthScheme

        public static AuthScheme selectAuthScheme​(Header[] challenges)
                                           throws MalformedChallengeException
        Chooses the strongest authentication scheme supported from the array of authentication challenges. Currently only NTLM, Digest, Basic schemes are recognized. The NTLM scheme is considered the strongest and is preferred to all others. The Digest scheme is preferred to the Basic one which provides no encryption for credentials. The Basic scheme is used only if it is the only one supported.
        Parameters:
        challenges - The array of authentication challenges
        Returns:
        The strongest authentication scheme supported
        Throws:
        MalformedChallengeException - is thrown if an authentication challenge is malformed
        UnsupportedOperationException - when none of challenge types available is supported.
