Interface PaData

All Known Implementing Classes:

PaEncTimestamp

public interface PaData

An interface to pre-authentication data passed to an Authentication or Ticket Granting service in a ticket request or returned from the service in a response.

PaData consists of a typed application-specific byte array. Several PaData types have been or are being standardized at the IETF. Supported types in this release are PA_TGS_REQ and PA_PW_SALT which are handled transparently, and PA_ENC_TIMESTAMP for which the class PaEncTimeStamp is available.

PaData is defined in RFC1510 as the ASN.1 structure

    PA-DATA ::=  SEQUENCE {
                 padata-type[1]        INTEGER,
                 padata-value[2]       OCTET STRING,
                         -- might be encoded AP-REQ
               }
 

Users requiring pre-authentication other than encrypted timestamp in an initial authentication request can create their own PaData implementation.
