Constructor Detail

MessageImprint

public MessageImprint(oracle.security.crypto.core.AlgorithmIdentifier alg,
              byte[] message,
              boolean hashMessage)
               throws java.security.NoSuchAlgorithmException

Constructs a new MessageImprint object initialized with the given paramters.

Parameters:

alg - The hashing algorithm.

message - Either the data for which a hash is to be created or the hash itself.

hashMessage - If true, the data passed in the message parameter will be hashed; if false, the data passed in the message parameter is assumed to be the hash.

Throws:

AlgorithmIdentifierException - If the hashing algorithm is not supported

java.security.NoSuchAlgorithmException

Parameters:

is - The input stream.

Throws:

If - an I/O error occurs.
