Constructor Details

AuthenticatedEntry

public AuthenticatedEntry(String mac,
                          int macLen,
                          Properties properties)

Method Details

authenticate

public void authenticate(byte[] key)
            throws IOException,
                   InvalidKeyException
Computes the mac over this envelope's data. This method must be called before this entry in encoded.
Parameters:
key - The key to authenticate with.
Throws:
IOException - If encoding fails.
InvalidKeyException - If the supplied key is bad.

decode

public static AuthenticatedEntry decode(DataInputStream in)
            throws IOException

encodePayload

protected void encodePayload()
            throws IOException
Overrides:
encodePayload in interface EnvelopeEntry

verify

public void verify(byte[] key)
            throws InvalidKeyException
Verifies this entry's payload. This method will unmask this entry, thus it must be called before accessing its contents.
Parameters:
key - The key to use to authenticate.
Throws:
InvalidKeyException - If the given key is improper.
