|
55 |
* |
|
56 |
* 1. static fromJAAS(): Creates a Context using a JAAS login config entry |
|
57 |
* 2. static fromUserPass(): Creates a Context using a username and a password |
|
58 |
* 3. delegated(): A new context which uses the delegated credentials from a |
|
59 |
* previously established acceptor Context |
|
60 |
* |
|
61 |
* Two context initiators, which create the GSSContext object inside: |

63 |
* 1. startAsClient() |
|
64 |
* 2. startAsServer() |
|

* Privileged action: |
|
67 |
* doAs(): Performs an action in the name of the Subject |
|
68 |

|
69 |
* Handshake process: |
|
70 |
* static handShake(initiator, acceptor) |
|
71 |
* |
|
72 |
* A four-phase typical data communication which includes all four GSS |
