Wrap Key

Wrapping a key enables secure transfer of the key from one place to another. CADP for Java KMIP provider wraps an NAEKey object by encrypting it with a specified AES Symmetric Key.

To wrap a key:

1. Create a symmetric key and a symmetric wrapping key.

2. Register a normal AES symmetric key.

   String wrapping_keybytes = "49E3BD09F079E4F8842F1C6620FFF6EC"; uniqueIdentifier_wrappingkey = key_wrappingkey.registerKe (IngrianProvider.hex2ByteArray(wrapping_keybytes), algorithm, keyFormat, spec);
   

3. Register a symmetric wrapping key.

   String wrapped_keybytes = "92F6355221CC38DF5F374275631C774D"; uniqueIdentifier_wrappedkey = key_wrappedkey.registerKe (IngrianProvider.hex2ByteArray(wrapped_keybytes), algorithm, keyFormat, spec2);
   

4. Get the encrypted key bytes of the key using Wrapping key. Use the wrap() method of the KMIPSession API.

   byte[] byte_wrappedkey = session.wrapKey(wrapped_key, initialAttributes1);
