Constructor Detail

CkiMessageDigest

public CkiMessageDigest()

Empty constructor. If used, the setAlgID(oracle.security.crypto.core.AlgorithmIdentifier) method must be called before any other methods.

CkiMessageDigest

public CkiMessageDigest(oracle.security.crypto.core.AlgorithmIdentifier algID)
                 throws oracle.security.crypto.core.AlgorithmIdentifierException

Creates a new CkiMessageDigest object with the given AlgorithmIdentifier.

Parameters:

algID - The AlgorithmIdentifier representing a MessageDigest algorithm.

Throws:

oracle.security.crypto.core.AlgorithmIdentifierException

Method Detail
