HarmonyOS 鸿蒙Next解密中文乱码

问题描述

CryptoJS鸿蒙版aes解密，中文乱码

export function decryptByAESByKey(aesEncryptKey: string,plainText: string): string { 
  const key: string = CryptoJS.enc.Utf8.parse(aesEncryptKey); 
  const iv: string = CryptoJS.enc.Utf8.parse(’’); 
  let encryptedHexStr: [] = CryptoJS.enc.Hex.parse(plainText); 
  let srcs: string = CryptoJS.enc.Base64.stringify(encryptedHexStr); 
  let decrypt: string = CryptoJS.AES.decrypt(srcs, key, 
    { iv: iv, mode: CryptoJS.mode.ECB, padding: CryptoJS.pad.Pkcs7 } 
  ).toString(CryptoJS.enc.Utf8); 
  return decrypt.toString(); 
}
<button style="position: absolute; padding: 4px 8px 0px; cursor: pointer; top: 8px; right: 8px; font-size: 14px;">复制</button>

解决方案

请使用下面这种写法

decrypt(word: ESObject, key: ESObject, iv: ESObject): ESObject { 
  // let encryptedHexStr: ESObject = CryptoJS.enc.Hex.parse(word); 
  // const srcs: ESObject = CryptoJS.enc.Base64.stringify(encryptedHexStr); 
  const decrypt: ESObject = CryptoJS.AES.decrypt(word, key, { 
    iv: iv, 
    mode: CryptoJS.mode.ECB, 
    padding: CryptoJS.pad.Pkcs7 
  }); 
  const decryptedStr: ESObject = decrypt.toString(CryptoJS.enc.Utf8); 
  return decryptedStr.toString(); 
} 
AES加密的密钥长度需求16字节，不足在后面补"\0"，如：f901c133de\0\0\0\0\0\0
