Class ETypeInfo2Entry

java.lang.Object
  org.apache.directory.shared.asn1.AbstractAsn1Object
      org.apache.directory.shared.kerberos.components.ETypeInfo2Entry

All Implemented Interfaces:

org.apache.directory.shared.asn1.Asn1Object

public class ETypeInfo2Entry
extends org.apache.directory.shared.asn1.AbstractAsn1Object

Provides encryption info information sent to the client. The ASN.1 grammar for this structure is :

 ETYPE-INFO2-ENTRY        ::= SEQUENCE {
            etype           [0] Int32,
            salt            [1] KerberosString OPTIONAL,
            s2kparams       [2] OCTET STRING OPTIONAL
    }

Creates a new instance of ETypeInfo2Entry.

Method Detail

getSalt

public String getSalt()

Returns the salt.

Returns:

The salt.

setSalt

public void setSalt(String salt)

Parameters:

salt - the salt to set

getS2kparams

public byte[] getS2kparams()

Returns the s2kparams.

Returns:

The s2kparams.

setS2kparams

public void setS2kparams(byte[] s2kparams)

Parameters:

s2kparams - the s2kparams to set

getEType

public EncryptionType getEType()

computeLength

public int computeLength()

Compute the ETYPE-INFO2-ENTRY length

 ETYPE-INFO-ENTRY :
 
 0x30 L1 ETYPE-INFO2-ENTRY sequence
  |
  +--> 0xA0 L2 etype tag
  |     |
  |     +--> 0x02 L2-1etype (int)
  |
  +--> 0xA1 L3 salt tag
  |     |
  |     +--> 0x1B L3-1 salt (KerberosString)
  |
  +--> 0xA2 L4 s2kparams tag
        |
        +--> 0x04 L4-1 salt (OCTET STRING)
        
  where L1 = L2 + length(0xA0) + length(L2) +
             L3 + length(0xA1) + length(L3) +
             L4 + length(0xA2) + length( L4)
  and
  L2 = L2-1 + length(0x02) + length( L2-1) 
  L3 = L3-1 + length(0x1B) + length( L3-1) 
  L4 = L4-1 + length(0x04) + length( L4-1) 
  

encode

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

Encode the ETYPE-INFO2-ENTRY message to a PDU.

 ETYPE-INFO2-ENTRY :
 
 0x30 LL
   0xA0 LL 
     0x02 0x01 etype
   0xA1 LL 
     0x1B LL salt
   0xA2 LL
