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
