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 }- Since:

KerberosCredMessage
public KerberosCredMessage(KerberosPrincipal sender, KerberosPrincipal recipient, byte[] message)
Constructs aKerberosCredMessageobject.The contents of the
messageargument are copied; subsequent modification of the byte array does not affect the newly created object.- Parameters:
sender- the sender of the messagerecipient- the recipient of the messagemessage- 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:
destroyin interfaceDestroyable
-
toString
public String toString()
Returns an informative textual representation of thisKerberosCredMessage.
-
hashCode
public int hashCode()
Returns a hash code for thisKerberosCredMessage.- Overrides:
hashCodein 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 thisKerberosCredMessagefor equality. Returns true if the given object is also aKerberosCredMessageand the twoKerberosCredMessageinstances are equivalent. More formally twoKerberosCredMessageinstances are equal if they have equal sender, recipient, and encoded KRB_CRED messages. A destroyedKerberosCredMessageobject is only equal to itself.- Overrides:
equalsin classObject- Parameters:
other- the object to compare to- Returns:
- true if the specified object is equal to this
KerberosCredMessage, false otherwise. - See Also:
