org.apache.directory.shared.kerberos.components.PaData

All Implemented Interfaces:

org.apache.directory.api.asn1.Asn1Object

public class PaData
extends Object
implements org.apache.directory.api.asn1.Asn1Object

The Pre-Authentication data. The ASN.1 GRAMMAR IS :

 PA-DATA         ::= SEQUENCE {
         -- NOTE: first tag is [1], not [0]
         padata-type     [1] Int32,
         padata-value    [2] OCTET STRING -- might be encoded AP-REQ
 }

paDataType -

paDataValue -

Method Detail

getPaDataType

public PaDataType getPaDataType()

Returns the PaDataType.

Returns:

The PaDataType.

setPaDataType

public void setPaDataType(int paDataType)

Set the PA-DATA type

Parameters:

paDataType - The PA-DATA type

setPaDataType

public void setPaDataType(PaDataType paDataType)

Set the PA-DATA type

Parameters:

paDataType - The PA-DATA type

getPaDataValue

public byte[] getPaDataValue()

computeLength

public int computeLength()

Compute the PreAuthenticationData length

 PreAuthenticationData :
 
 0x30 L1 PreAuthenticationData sequence
  |
  +--> 0xA0 L2 padata-type tag
  |     |
  |     +--> 0x02 L2-1 padata-type (int)
  |
  +--> 0xA1 L3 padata-value tag
        |
        +--> 0x04 L3-1 padata-value (OCTET STRING)
        
  where L1 = L2 + lenght(0xA0) + length(L2) +
             L3 + lenght(0xA1) + length(L3) 
  and
  L2 = L2-1 + length(0x02) + length( L2-1) 
  L3 = L3-1 + length(0x04) + length( L3-1) 
  

Specified by:

computeLength in interface org.apache.directory.api.asn1.Asn1Object

encode

public ByteBuffer encode(ByteBuffer buffer)
                  throws org.apache.directory.api.asn1.EncoderException

Encode the PreAuthenticationData message to a PDU.

 PreAuthenticationData :
 
 0x30 LL
   0xA1 LL 
     0x02 0x01 padata-type
   0xA2 LL 
     0x04 LL padata-value
 

Specified by:

encode in interface org.apache.directory.api.asn1.Asn1Object

Parameters:

buffer - The buffer where to put the PDU. It should have been allocated before, with the right size.

Returns:

The constructed PDU.

Throws:

org.apache.directory.api.asn1.EncoderException
