Ethereum MAC Module

This module provides the implementation of the Ethereum MAC (Message Authentication Code) construction, as specified in the Ethereum RLPx protocol.

The Ethereum MAC is a nonstandard MAC construction that utilizes AES-256 (as a block cipher) and Keccak-256. It is specifically designed for messages of 128 bits in length and is not intended for general MAC use.

For more information, refer to the Ethereum MAC specification.
