#include <cipher_registry.hh>

Public Types
using	Factory = std::function< std::unique_ptr< Cipher< 16 > >(const uint8_t *key, const std::array< uint8_t, 16 > &init_vector)>
	Creates a block cipher for the given 32-byte key and IV.

Public Member Functions
void	Register (Database::Cipher cipher, Factory factory)
	Registers/overwrites the factory for a payload cipher id.
std::unique_ptr< Cipher< 16 > >	Create (Database::Cipher cipher, const uint8_t *key, const std::array< uint8_t, 16 > &init_vector) const
	Creates a block cipher, or throws UnsupportedFeatureError.
bool	Contains (Database::Cipher cipher) const
	Returns whether a block-cipher factory is registered for cipher.

Static Public Member Functions
static CipherRegistry &	Instance ()
	Returns the process-wide registry.

Detailed Description

Process-wide registry for 16-byte block ciphers.

The built-in AES and Twofish factories are registered by the registry constructor. External implementations can be added with Register() and are then usable anywhere the core creates a block cipher (KDB/KDBX import and export). ChaCha20 is a stream cipher with its own code path; it is not a block-cipher registration.
