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.

Method Detail

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
void dispose() throws GSSException
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
GSSNameSpi getName() throws GSSException
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
int getInitLifetime() throws GSSException
Returns the init lifetime remaining.- Returns:
- the init lifetime remaining in seconds
- Throws:
GSSException
- may be thrown
-
getAcceptLifetime
int getAcceptLifetime() throws GSSException
Returns the accept lifetime remaining.- Returns:
- the accept lifetime remaining in seconds
- Throws:
GSSException
- may be thrown
-
getLifetime
int getLifetime() throws GSSException
Returns the lifetime remaining. This should take into account the credential usage, and return the appropriate lifetime. See RFC 2078 for details.- Returns:

- Throws:
GSSException
- may be thrown
-
getUsage
int getUsage() throws GSSException
Returns the credential usage. This must be one GSSCredential.ACCEPT_ONLY, GSSCredential.INITIATE_ONLY, or GSSCredential.INITIATE_AND_ACCEPT.- Returns:
- the credential usage
- 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
