/* global define */ /* eslint-disable */ /** * XOR, or exclusive or, is a logical bitwise operation that stands for "exclusive or." * In the context of binary numbers, XOR compares corresponding bits of two operands and * produces a new result. The XOR operation returns true (or 1) for bits where the operands differ. * * Note: This class is a simple obfuscation technique and should not be used for securing sensitive data. * * Here's the truth table for XOR: * * A | B | A XOR B * ----------------- * 0 | 0 | 0 * 0 | 1 | 1 * 1 | 0 | 1 * 1 | 1 | 0 * * In binary, XOR is often denoted by the symbol ^. * Here's an example of XOR operation on binary numbers: * * 1101 (13 in decimal) * ^ 1010 (10 in decimal) * ------------------------ * 0111 (7 in decimal) * * Example Usage: * * // Instantiate the plugin with a custom encryption key. * const xorInstance = new WPFormsXOR({ * key: 55, // Use any number as the encryption key. * }); * * // Example object to encrypt. * const dataToEncrypt = { * age: 30, * name: 'Sullie', * city: 'Texas', * }; * * // Encrypt the object. * const encryptedValue = xorInstance.encrypt(dataToEncrypt); * console.log('Encrypted:', encryptedValue); * * // Decrypt the string. * const decryptedObject = xorInstance.decrypt(encryptedValue); * console.log('Decrypted:', decryptedObject); */ /* eslint-enable */ ( function( root, factory ) { const pluginName = 'WPFormsXOR'; if ( typeof define === 'function' && define.amd ) { define( [], factory( pluginName ) ); } else if ( typeof exports === 'object' ) { module.exports = factory( pluginName ); } else { root[ pluginName ] = factory( pluginName ); } // eslint-disable-next-line max-lines-per-function }( this, function( pluginName ) { // eslint-disable-next-line strict 'use strict'; /** * Plugin Error Object. * * @since 1.8.6 * * @class PluginError * * @augments Error */ class PluginError extends Error { /** * Constructor. * * @since 1.8.6 * * @param {string} message The error message. */ constructor( message ) { super( message ); this.name = pluginName; } } /** * Plugin Object. * * @since 1.8.6 * * @class Plugin */ class Plugin { // Default settings. static defaults = { // The encryption key is a crucial component in encryption algorithms, // including the XOR encryption used in the provided code. // The key is a value used to control the transformation // of the data during encryption and decryption. key: 42, // You can use any number. }; /** * Constructor. * * @since 1.8.6 * * @param {Object} args The argument object. */ constructor( args ) { // Merge the default settings with the provided settings. this.args = Object.assign( {}, Plugin.defaults, args ); } /** * Encrypt an object using XOR encryption. * * @since 1.8.6 * * @param {Object} obj The object to encrypt. * * @return {string} The encrypted object as a string. */ encrypt( obj ) { // Bail if the input is not an object. if ( typeof obj !== 'object' ) { throw new PluginError( 'Invalid input.
