crypto-js使用

crypto-js使用 :

const cryptoJs = require('crypto-js')

function getKey(key = "1234123412341234") {
    
  return cryptoJs
    .SHA1(cryptoJs.SHA1(key))
    .toString()
    .substring(0, 32);
}

function aesEncrypt(data, key) {
    
  console.log('加密之前的data:', data+' key:'+ key + ' 真实的key:'+ getKey(key));

  const KEY = cryptoJs.enc.Hex.parse(getKey(key));
  const IV = cryptoJs.enc.Hex.parse(getKey(key));

  if (typeof data === "object") {
    
    try {
    
      data = JSON.stringify(data);
    } catch (error) {
    
      console.log("加密失败:", error);
    }
  }

  let encrypt = cryptoJs.AES.encrypt(
    data,
    KEY,
    {
    
      iv: IV,
      mode: cryptoJs.mode.ECB,
      padding: cryptoJs.pad.Pkcs7
    }
  );
  console.log("加密之后的数据:", encrypt.ciphertext.toString());
  return encrypt.ciphertext.toString();
}

function aesDecrypt(data, key) {
    
  console.log('解密之前的data:', data+' key:'+ key + ' 真实的key:'+ getKey(key));

  const KEY = cryptoJs.enc.Hex.parse(getKey(key));
  const IV = cryptoJs.enc.Hex.parse(getKey(key));
  let str = cryptoJs.enc.Base64.stringify(cryptoJs.enc.Hex.parse(data));
  let decrypt = cryptoJs.AES.decrypt(
    str,
    KEY,
    {
    
      iv: IV,
      mode: cryptoJs.mode.ECB,
      padding: cryptoJs.pad.Pkcs7
    }
  );
  console.log('解密后的数据：', decrypt.toString(cryptoJs.enc.Utf8).toString())
  return decrypt.toString(cryptoJs.enc.Utf8);
}

let obj = {
     
  name: '狠人大帝'
}
let a = aesEncrypt(obj, '45674567456745674567')
console.log('加密后的a====', a);
let a1 = aesDecrypt(a, '45674567456745674567')
console.log('解密后的a1', a1)


// export { aesEncrypt, aesDecrypt };
