java.lang.Object

javax.crypto.KEM.Encapsulated

Enclosing class:: KEM

public static final class KEM.Encapsulated extends Object

This class specifies the return value of the encapsulate method of a Key Encapsulation Mechanism (KEM), which includes the shared secret (as a SecretKey), the key encapsulation message, and optional parameters.

Note: the key encapsulation message can be also referred to as ciphertext.

Constructor Details

Encapsulated

public Encapsulated(SecretKey key, byte[] encapsulation, byte[] params)

Constructs an Encapsulated object.

Parameters:: key - the shared secret as a key, must not be null.; encapsulation - the key encapsulation message, must not be null. The contents of the array are copied to protect against subsequent modification.; params - optional parameters, can be null. The contents of the array are copied to protect against subsequent modification.
Throws:: NullPointerException - if key or encapsulation is null

Method Details

key

public SecretKey key()

Returns the SecretKey.

Returns:: the secret key

encapsulation

public byte[] encapsulation()

Returns the key encapsulation message.

Returns:: the key encapsulation message. A new copy of the byte array is returned.

params

public byte[] params()

Returns the optional parameters in a byte array.

Returns:: the optional parameters in a byte array or null if not specified. A new copy of the byte array is returned.
