javax.security.auth.kerberos.KerberosCredMessage
- All Implemented Interfaces:
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
Constructs aKerberosCredMessageobject.The contents of the
messageargument are copied; subsequent modification of the byte array does not affect the newly created object.- Parameters:

Method Details
-
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
Returns the sender of this message.- Returns:
- the sender
- Throws:
IllegalStateException- if the object is destroyed
-
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
Returns an informative textual representation of thisKerberosCredMessage. -
hashCode
public int hashCode()Returns a hash code for thisKerberosCredMessage. -
equals
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.
