     * Represents the MlKem1024 class, which extends the MlKem1024Base class.

     * This class extends the MlKem1024Base class and provides specific implementation for MlKem1024.
     *
     * @deprecated Use {@link createMlKem1024} instead. This async class-based API will be removed in a future release.
     *
     * @remarks
     *
     * MlKem1024 is a specific implementation of the ML-KEM key encapsulation mechanism.
     *
     * @example
     *
     * ```ts
     * // Using jsr:
     * import { createMlKem1024 } from "@dajiaji/mlkem";
     * // Using npm:
     * // import { createMlKem1024 } from "mlkem"; // or "crystals-kyber-js"
     *
     * const recipient = await createMlKem1024();
     * const [pkR, skR] = recipient.generateKeyPair();
     *
     * const sender = await createMlKem1024();
     * const [ct, ssS] = sender.encap(pkR);
     *
     * const ssR = recipient.decap(ct, skR);
     * // ssS === ssR
     * ```
