/**
* Contains the internal classes that handle the cryptographic defined by the message formats and
* algorithms. The package also includes auxiliary classes that implement serialization of
* encryption context, parser for deserializing bytes into primitives, and generation of random
* bytes.
*
* No classes in this package are intended for public consumption. They
* may be changed at any time without concern for API compatibility.
*
*
* -
* the CryptoHandler interface that defines the contract for the methods that must be implemented by
* classes that perform encryption and decryption in this library.
*
*
-
* the EncryptionHandler and DecryptionHandler classes handle the creation and parsing of the
* ciphertext headers as described in the message format. These two classes delegate the actual
* encryption and decryption of content to the Block and Frame handlers.
*
*
-
* the BlockEncryptionHandler and BlockDecryptionHandler classes handle the encryption and
* decryption of content stored as a single-block as described in the message format.
*
*
-
* the FrameEncryptionHandler and FrameDecryptionHandler classes handle the encryption and
* decryption of content stored as frames as described in the message format.
*
*
-
* the CipherHandler that provides methods to cryptographically transform bytes using a block
* cipher. Currently, it only uses AES-GCM block cipher.
*
*
-
* the EncContextSerializer provides methods to serialize a map containing the encryption context
* into bytes, and deserialize bytes into a map containing the encryption context.
*
*
-
* the PrimitivesParser provides methods to parse primitive types from bytes. These methods are used
* by deserialization code.
*
*
-
* the ContentAadGenerator provides methods to generate the Additional Authenticated Data (AAD) used
* in encrypting the content.
*
*
-
* the Constants class that contains the constants and default values used in the library.
