    Class CrossRsdp128Fast

    CROSS-rsdp-128-fast signature algorithm wrapper class

    CrossRsdp128Fast

    High-level wrapper for CROSS-rsdp-128-fast signature operations. Provides secure key generation, message signing, and signature verification with automatic memory management.

    Memory Management:

    • All WASM memory is managed internally
    • Call destroy() when finished to free resources
    • Do not use instance after calling destroy()
    const sig = await createCrossRsdp128Fast(moduleFactory);

    // Generate keypair
    const { publicKey, secretKey } = sig.generateKeyPair();

    // Sign message
    const message = new TextEncoder().encode('Hello, quantum world!');
    const signature = sig.sign(message, secretKey);

    // Verify signature
    const isValid = sig.verify(message, signature, publicKey);
    console.log('Valid:', isValid); // true

    // Cleanup
    sig.destroy();

      console.log(sig.info.name);           // 'CROSS-rsdp-128-fast'
      console.log(sig.info.securityLevel);  // 1

    Methods

    • Generate a new CROSS-rsdp-128-fast keypair

      Returns { publicKey: Uint8Array; secretKey: Uint8Array }

      If instance is destroyed

      If key generation fails

      const { publicKey, secretKey } = sig.generateKeyPair();
      console.log('Public key:', publicKey.length);  // 77 bytes
      console.log('Secret key:', secretKey.length);  // 32 bytes

    • Sign a message with CROSS-rsdp-128-fast

      Parameters

      • message: Uint8Array<ArrayBufferLike>

        Message to sign (any length)

      • secretKey: Uint8Array<ArrayBufferLike>

        Secret key (32 bytes)

      Returns Uint8Array<ArrayBufferLike>

      Signature (variable length, max 18432 bytes)

      If instance is destroyed

      If secret key size is invalid

      If signing fails

      const message = new TextEncoder().encode('Sign this message');
      const signature = sig.sign(message, secretKey);
      console.log('Signature length:', signature.length);

    • Verify a CROSS-rsdp-128-fast signature

      Parameters

      • message: Uint8Array<ArrayBufferLike>

        Original message

      • signature: Uint8Array<ArrayBufferLike>

        Signature to verify

      • publicKey: Uint8Array<ArrayBufferLike>

        Public key (77 bytes)

      Returns boolean

      True if signature is valid, false otherwise

      If instance is destroyed

      If public key or signature size is invalid

      const isValid = sig.verify(message, signature, publicKey);
      if (isValid) {
        console.log('Signature is valid!');
      } else {
        console.log('Signature verification failed');
      }

    • Free WASM resources

      Returns void

      Releases all WASM memory associated with this instance. The instance cannot be used after calling destroy().

      sig.destroy();
      // sig is now unusable
