Package com.sun.gssapi
Interface GSSCredSpi
public interface GSSCredSpi
This interface is implemented by each mechanism to provide the
functionality of a credential. Each GSSCredential uses provider
objects implementing this interface. A GSSCredential may have
several credential elements underneath it, but each GSSCredSpi
object can represent at most 1 credential element.

init
void init(GSSNameSpi desiredName, int initLifetime, int acceptLifetime, int usage) throws GSSException Initialized the credential object. Called after the object is first instantiated.- Parameters:
desiredName
- - desired name of the principalinitLifetime
- - desired lifetime for the init credential; 0 signals use mechanism defaultacceptLifetime
- - desired lifetime for the accept credential; 0 signals use mechanism defaultusage
- - the desired usage for this credential- Throws:
GSSException
-
dispose
Called to invalidate this credential element and release any system recourses and cryptographic information owned by the credential.- Throws:
GSSException
- with major codes NO_CRED and FAILURE
-
getName
Returns the principal name for this credential. The name is in mechanism specific format.- Returns:
- GSSNameSpi representing principal name of this credential
- Throws:
GSSException
- may be thrown
-
getInitLifetime
Returns the init lifetime remaining.- Returns:
- the init lifetime remaining in seconds
- Throws:
GSSException
- may be thrown
-
getAcceptLifetime
Returns the accept lifetime remaining.- Returns:
- the accept lifetime remaining in seconds
- Throws:
GSSException

- Throws:
GSSException
- may be thrown
-
getMechanism
Oid getMechanism()Returns the oid representing the underlying credential mechanism oid.- Returns:
- the Oid for this credential mechanism
- Throws:
GSSException
- may be thrown
