/**
* Represents the MlKem768 class, which extends the MlKemBase class.
*
* This class extends the MlKemBase class and provides specific implementation for MlKem768.
*
* @remarks
*
* MlKem768 is a specific implementation of the ML-KEM key encapsulation mechanism.
*
* @example
*
* ```ts
* // Using jsr:
* import { MlKem768 } from "@dajiaji/mlkem";
* // Using npm:
* // import { MlKem768 } from "mlkem"; // or "crystals-kyber-js"
*
* const recipient = new MlKem768();
* const [pkR, skR] = await recipient.generateKeyPair();
*
* const sender = new MlKem768();
* const [ct, ssS] = await sender.encap(pkR);
*
* const ssR = await recipient.decap(ct, skR);
* // ssS === ssR
* ```
