                              throws XrootdException

Throws:

XrootdException

Method Detail

getProtocolVersion

public int getProtocolVersion()

Specified by:

getProtocolVersion in class GSIRequestHandler

handleCertReqStep

public XrootdResponse<AuthenticationRequest> handleCertReqStep(AuthenticationRequest request)
                                                        throws XrootdException

Specified by:

handleCertReqStep in class GSIServerRequestHandler

Throws:

XrootdException

handleCertStep

public XrootdResponse<AuthenticationRequest> handleCertStep(AuthenticationRequest request)
                                                     throws XrootdException

Handle the second step (reply by client to authmore). This involves finalizing the session key, verifying rsa certificate and decrypting and verifying the signed hash. A check is then made for the existence of a proxy. If there is none, a request is generated.

Specified by:

handleCertStep in class GSIServerRequestHandler

Parameters:

request - AuthenticationRequest received by the client

Returns:

either an AuthenticationResponse with step kXGS_pxyreq if there is no currently valid proxy, or and OK response.

Throws:

XrootdException

handleSigPxyStep

public XrootdResponse<AuthenticationRequest> handleSigPxyStep(AuthenticationRequest request)
                                                       throws XrootdException

Decrypt main bucket, check signed rtag, and then use included signed certificate to finalize proxy (and send to the credential store).

Specified by:

handleSigPxyStep in class GSIServerRequestHandler

Returns:

OKResponse if all is well.

Throws:

XrootdException

isFinished

public boolean isFinished(AuthenticationRequest request)

Specified by:

isFinished in class GSIServerRequestHandler

getSyncCipherMode

protected java.lang.String getSyncCipherMode()

Specified by:

getSyncCipherMode in class GSIRequestHandler
