    Class ClassicMcEliece6960119

    Classic-McEliece-6960119 wrapper class providing high-level KEM operations

    This class wraps the low-level WASM module to provide a user-friendly interface for Classic-McEliece-6960119 operations with automatic memory management and input validation.

    Methods

    • Generate a new keypair for Classic-McEliece-6960119

      Generates a public/private keypair using the algorithm's internal random number generator. The secret key must be kept confidential.

      Returns { publicKey: Uint8Array; secretKey: Uint8Array }

      If keypair generation fails

      If instance has been destroyed

      const { publicKey, secretKey } = kem.generateKeyPair();
      // publicKey: 1047319 bytes
      // secretKey: 13948 bytes (keep confidential!)

    • Encapsulate a shared secret using a public key

      Generates a random shared secret and encapsulates it using the provided public key. The shared secret can be used for symmetric encryption.

      Parameters

      • publicKey: Uint8Array<ArrayBufferLike>

        Recipient's public key (1047319 bytes)

      Returns { ciphertext: Uint8Array; sharedSecret: Uint8Array }

      If public key is invalid

      If encapsulation fails

      If instance has been destroyed

      const { ciphertext, sharedSecret } = kem.encapsulate(recipientPublicKey);
      // ciphertext: 194 bytes (send to recipient)
      // sharedSecret: 32 bytes (use for symmetric encryption)

    • Decapsulate a shared secret using a secret key

      Recovers the shared secret from a ciphertext using the secret key. The recovered shared secret will match the one generated during encapsulation.

      Parameters

      • ciphertext: Uint8Array<ArrayBufferLike>

        Ciphertext received (194 bytes)

      • secretKey: Uint8Array<ArrayBufferLike>

        Recipient's secret key (13948 bytes)

      Returns Uint8Array<ArrayBufferLike>

      Recovered shared secret (32 bytes)

      If inputs are invalid

      If decapsulation fails

      If instance has been destroyed

      const sharedSecret = kem.decapsulate(ciphertext, mySecretKey);
      // sharedSecret: 32 bytes (matches sender's shared secret)

    • Clean up resources and free WASM memory

      This method should be called when you're done using the instance to free WASM memory. After calling destroy(), the instance cannot be used for further operations.

      Returns void

      const kem = await createClassicMcEliece6960119();
      // ... use kem ...
      kem.destroy();
