AES

前端crypto-js

import CryptoJS from 'crypto-js';

const AES = {
  key: '1234567890123456', // 必须16个字符
  iv: '1234567890123456', // 必须16个字符
};

  encrypt(str) {
    if (!str) {
      return '';
    }
    const key = CryptoJS.enc.Utf8.parse(AES.key);
    const iv = CryptoJS.enc.Utf8.parse(AES.iv);

    const encryptStr = CryptoJS.enc.Utf8.parse(str);
    const encrypted = CryptoJS.AES.encrypt(encryptStr, key, {
      iv,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7,
    });
    return CryptoJS.enc.Base64.stringify(encrypted.ciphertext);
  },
  decrypt(str) {
    if (!str) {
      return '';
    }
    const key = CryptoJS.enc.Utf8.parse(AES.key);
    const iv = CryptoJS.enc.Utf8.parse(AES.iv);
    const bytes = CryptoJS.AES.decrypt(str, key, {
      iv,
      mode: CryptoJS.mode.CBC,
      padding: CryptoJS.pad.Pkcs7,
    });

    return CryptoJS.enc.Utf8.stringify(bytes);
  },
