public PAForUserEnc(DerValue encoding, EncryptionKey key) throws Asn1Exception, KrbException, IOException

Constructs a PA-FOR-USER object from a DER encoding.

Parameters
encoding:DerValue

the input object

key:EncryptionKey

the key to verify the checksum inside encoding

Exceptions
KrbException:
if the verification fails. Note: this method is now only used by test KDC, therefore the verification is ignored (at the moment).

getS4UByteArrayback to summary
public byte[] getS4UByteArray()

Returns S4UByteArray, the block to calculate checksum inside a PA-FOR-USER-ENC data structure. It includes: 1. userName.name-type encoded as a 4-byte integer in little endian byte order 2. all string values in the sequence of strings contained in the userName.name-string field 3. the string value of the userRealm field 4. the string value of auth-package field

public String toString()

Overrides java.lang.Object.toString.

Doc from java.lang.Object.toString.

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.
