Class KerberosCredMessage
- java.lang.Object
-
- javax.security.auth.kerberos.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 }

Constructor Detail
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
Method Detail
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 interfaceDestroyable
toString
public String toString()
Returns an informative textual representation of this KerberosCredMessage
.
- Overrides:
-
toString
in classObject
- Returns:
- an informative textual representation of this
KerberosCredMessage
.
hashCode
public int hashCode()
Returns a hash code for this KerberosCredMessage
.
- Overrides:
-
hashCode
in classObject
- Returns:
- a hash code for this
KerberosCredMessage
. - See Also:

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 classObject
- Parameters:
-
other
- the object to compare to - Returns:
- true if the specified object is equal to this
KerberosCredMessage
, false otherwise. - See Also:
