Class ETypeInfoEntry

java.lang.Object

org.apache.directory.shared.kerberos.components.ETypeInfoEntry

All Implemented Interfaces:

org.apache.directory.api.asn1.Asn1Object

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

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

 ETYPE-INFO-ENTRY        ::= SEQUENCE {
            etype           [0] Int32,
            salt            [1] OCTET STRING OPTIONAL
    }

Constructor Detail

ETypeInfoEntry

public ETypeInfoEntry(EncryptionType etype,
              byte[] salt)

Creates a new instance of ETypeInfoEntry.

Parameters:

etype - the Encryption type

salt - the salt

ETypeInfoEntry

public ETypeInfoEntry()

Creates a new instance of ETypeInfoEntry.

Method Detail

getSalt

public byte[] getSalt()

Returns the salt.

Returns:

The salt.

setSalt

public void setSalt(byte[] salt)

Parameters:

salt - the salt to set

getEType

public EncryptionType getEType()

Returns the EncryptionType.

Returns:

The EncryptionType.

setEType

public void setEType(EncryptionType etype)

Parameters:

encryptionType - the encryptionType to set

computeLength

public int computeLength()

Compute the ETYPE-INFO-ENTRY length

 ETYPE-INFO-ENTRY :
 
 0x30 L1 ETYPE-INFO-ENTRY sequence
  |
  +--> 0xA0 L2 etype tag
  |     |
  |     +--> 0x02 L2-1etype (int)
  |
  +--> 0xA1 L3 salt tag
        |
        +--> 0x04 L3-1 salt (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 ETYPE-INFO-ENTRY message to a PDU.

 ETYPE-INFO-ENTRY :
 
 0x30 LL
   0xA1 LL 
     0x02 0x01 etype
   0xA2 LL 
     0x04 LL salt
 

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

toString

public String toString()

Overrides:

toString in class Object
