Aegis128LMACState

AEGIS-128L MAC state.

Manages the lifecycle of an aegis128l_mac_state object in a @nogc and @trusted context.

struct Aegis128LMACState {

this(const(ubyte)[] key, const(ubyte)[] nonce);

int update(const(ubyte)[] message);

int finalize(ubyte[] mac, size_t maclen);

int verify(const(ubyte)[] mac, size_t maclen);

void reset();

}

Constructors

this this(const(ubyte)[] key, const(ubyte)[] nonce): Initializes the AEGIS-128L MAC state with the provided key and nonce.

Destructor

~this ~this(): Destructor to clean up the MAC state.

Postblit

this(this) this(this): Disabled copy constructor to prevent state duplication.

Members

Functions

finalize int finalize(ubyte[] mac, size_t maclen): Finalizes the MAC computation, producing the MAC.
reset void reset(): Resets the MAC state for reuse with the same key and nonce.
update int update(const(ubyte)[] message): Updates the MAC state with a message chunk.
verify int verify(const(ubyte)[] mac, size_t maclen): Verifies a MAC against the computed MAC.

Examples

ubyte[16] key = [0x01, 0x02, ..., 0x10];
ubyte[16] nonce = [0x00, 0x01, ..., 0x0F];
ubyte[] message = [0x48, 0x65, 0x6C, 0x6C, 0x6F]; // "Hello"
ubyte[16] mac;

auto macState = Aegis128LMACState(key, nonce);
macState.update(message);
macState.finalize(mac[], 16);
