Constructor Detail

AuthenticatedEntry

public AuthenticatedEntry(java.lang.String mac,
                          int macLen,
                          Properties properties)
Method Detail

decode

public static AuthenticatedEntry decode(java.io.DataInputStream in)
                                 throws java.io.IOException
Throws:
java.io.IOException

authenticate

public void authenticate(byte[] key)
                  throws java.io.IOException,
                         java.security.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:
java.io.IOException - If encoding fails.
java.security.InvalidKeyException - If the supplied key is bad.

verify

public void verify(byte[] key)
            throws java.security.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:
java.security.InvalidKeyException - If the given key is improper.

encodePayload

protected void encodePayload()
                      throws java.io.IOException
Description copied from class: Entry
This method is called of subclasses when the payload data needs to be created.

Overrides:
encodePayload in class EnvelopeEntry
Throws:
java.io.IOException
