  +--org.zoolu.sip.authentication.DigestAuthentication

public class DigestAuthentication

extends java.lang.Object

The HTTP Digest Authentication as defined in RFC2617. It can be used to i) calculate an authentication response from an authentication request, or ii) validate an authentication response.
in the former case the DigestAuthentication is created based on a WwwAuthenticationHeader (or ProxyAuthenticationHeader), while in the latter case it is created based on an AuthorizationHeader (or ProxyAuthorizationHeader).

DigestAuthentication

protected DigestAuthentication()

Costructs a new DigestAuthentication.

                            AuthorizationHeader ah,
                            java.lang.String body,
                            java.lang.String passwd)

Costructs a new DigestAuthentication.

                            java.lang.String uri,
                            WwwAuthenticateHeader ah,

                            java.lang.String passwd)

Costructs a new DigestAuthentication.

Method Detail

toString

public java.lang.String toString()

Gets a String representation of the object.

Overrides:

toString in class java.lang.Object

checkResponse

public boolean checkResponse()

Whether the digest-response in the 'response' parameter in correct.

getAuthorizationHeader

public AuthorizationHeader getAuthorizationHeader()

Gets a new AuthorizationHeader based on current authentication attributes.

getProxyAuthorizationHeader

public ProxyAuthorizationHeader getProxyAuthorizationHeader()

Gets a new ProxyAuthorizationHeader based on current authentication attributes.

getResponse

public java.lang.String getResponse()

Calculates the digest-response.

If the "qop" value is "auth" or "auth-int":
KD ( H(A1), unq(nonce) ":" nc ":" unq(cnonce) ":" unq(qop) ":" H(A2) )

If the "qop" directive is not present:
KD ( H(A1), unq(nonce) ":" H(A2) )

main

public static void main(java.lang.String[] args)

Main method. It tests DigestAuthentication with the example provided in the RFC2617.
