Class KerberosCredMessage

All Implemented Interfaces:
Destroyable 
public final class KerberosCredMessage
extends Object
implements Destroyable

This class encapsulates a Kerberos 5 KRB_CRED message which can be used to send Kerberos credentials from one principal to another.

A KRB_CRED message is defined in Section 5.8.1 of the Kerberos Protocol Specification (RFC 4120) as:

KRB-CRED        ::= [APPLICATION 22] SEQUENCE {
            pvno            [0] INTEGER (5),
            msg-type        [1] INTEGER (22),
            tickets         [2] SEQUENCE OF Ticket,
            enc-part        [3] EncryptedData -- EncKrbCredPart
    }

KerberosCredMessage

public KerberosCredMessage(KerberosPrincipal sender,
                           KerberosPrincipal recipient,
                           byte[] message)

Constructs a KerberosCredMessage object.

The contents of the message argument are copied; subsequent modification of the byte array does not affect the newly created object.

Parameters:
sender - the sender of the message
recipient - the recipient of the message
message - the DER encoded KRB_CRED message
Throws:
NullPointerException - if any of sender, recipient or message is null

Methods

getEncoded

public byte[] getEncoded()

Returns the DER encoded form of the KRB_CRED message.

Returns:
a newly allocated byte array that contains the encoded form
Throws:
IllegalStateException - if the object is destroyed

getSender

public KerberosPrincipal getSender()

Returns the sender of this message.

Returns:
the sender
Throws:
IllegalStateException - if the object is destroyed

getRecipient

public KerberosPrincipal getRecipient()

Returns the recipient of this message.

Returns:
the recipient
Throws:
IllegalStateException - if the object is destroyed

destroy

public void destroy()

Destroys this object by clearing out the message.

Specified by:
destroy in interface Destroyable

toString

public String toString()

Returns an informative textual representation of this KerberosCredMessage.

Overrides:
toString in class Object
Returns:
an informative textual representation of this KerberosCredMessage.

hashCode

public int hashCode()

Returns a hash code for this KerberosCredMessage.

Overrides:
hashCode in class Object
Returns:
a hash code for this KerberosCredMessage.

Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)

equals

public boolean equals(Object other)

Compares the specified object with this KerberosCredMessage for equality. Returns true if the given object is also a KerberosCredMessage and the two KerberosCredMessage instances are equivalent. More formally two KerberosCredMessage instances are equal if they have equal sender, recipient, and encoded KRB_CRED messages. A destroyed KerberosCredMessage object is only equal to itself.

Overrides:
equals in class Object
Parameters:
other - the object to compare to
Returns:
true if the specified object is equal to this KerberosCredMessage, false otherwise.
