Class: Rex::Proto::Kerberos::Model::ApReq
- Defined in:
- lib/rex/proto/kerberos/model/ap_req.rb
Overview
This class provides a representation of a KRB_AP_REQ definition, containing the Kerberos protocol version number, the message type KRB_AP_REQ, an options field to indicate any options in use, and the ticket and authenticator themselves
