@secure-input/core

Framework-agnostic input obfuscation library with WASM encryption.

Installation

npm install @secure-input/core

Usage

import { SecureInput } from "@secure-input/core";

// Create instance
const secureInput = new SecureInput({
  onEncrypt: (encrypted) => {
    console.log("Encrypted:", encrypted);
  },
  onError: (error) => {
    console.error("Error:", error);
  },
  debug: true,
});

// Encrypt a value
const encrypted = await secureInput.encrypt("COUPON2024");

// Decrypt a value
const decrypted = await secureInput.decrypt(encrypted);

// Clean up
secureInput.destroy();

API
