       throws Asn1Exception,
              IOException,
              KrbException

Creates an KDCReq object from a DerValue object and asn1 type.

Parameters:

der - a DER value of an KDCReq object.

req_type - a encoded asn1 type value.

Throws:

Asn1Exception - if an error occurs while decoding an ASN1 encoded data.

IOException - if an I/O error occurs while reading encoded data.

Method Detail

init

protected void init(sun.security.util.DerValue encoding,
                    int req_type)
             throws Asn1Exception,
                    IOException,
                    KrbException

Initializes a KDCReq object from a DerValue. The DER encoding must be in the format specified by the KRB_KDC_REQ ASN.1 notation.

Parameters:

encoding - a DER-encoded KDCReq object.

req_type - an int indicating whether it's KRB_AS_REQ or KRB_TGS_REQ type

Throws:

Asn1Exception - if an error occurs while decoding an ASN1 encoded data.

IOException - if an I/O error occurs while reading encoded data.

KrbException - if an error occurs while constructing a Realm object, or a Krb object from DER-encoded data.

asn1Encode

public byte[] asn1Encode()
                  throws Asn1Exception,
                         IOException

Encodes this object to a byte array.

Returns:

an byte array of encoded data.

Throws:

Asn1Exception - if an error occurs while decoding an ASN1 encoded data.

IOException - if an I/O error occurs while reading encoded data.
