1 | The security context is a pair of GASSAPI data structures that contain shared state information, which is required in order that per-message security services may be provided. |
2 | The context initiator is authenticated to the responded, and may require that the responder is authenticated in turn. |
3 | The initiator may optionally give the responder the right to initiate further security context (delegation). |
4 | To establish and maintain the security context, some GSSAPI calls return a token data structure, which is a cryptographically protected opaque data type. The caller is responsible for transferring the token to the peer application, which should then pass it to a corresponding GSSAPI routine which will decode it and extract the information. |
