HarmonyOS MD5摘要算法与其他语言结果不同

示例代码如下：

let vd="88e10fbcd63aab1029be6b4935af6fa120240722200833";
let md5=cryptoFramework.createMd("MD5");
md5.updateSync({data:new Uint8Array(buffer.from(base,'utf-8').buffer)});
let ret=md5.digestSync();
let ba=(buffer.from(ret.data).toString("hex"));

ba="f22601f971479bbed7c00077cb30f559"

其他语言结果为："f67d8f14a5f9d8c6fc5c2d5d9e54574d"，在网上找的在线md5算法结果与之相同，请确认下问题在哪

用这个示例代码进行加密，会得到同一结果：

async function doMd5(bodyStr: string) {
  let TAG='Test-';
  let mdAlgName = 'MD5';
  let md = cryptoFramework.createMd(mdAlgName);
  console.info('mdAlgName:' + md.algName);
  let promiseMdUpdate = md.update({ data: stringToUint8Array(bodyStr) });

  promiseMdUpdate.then(() => {
    let PromiseMdDigest = md.digest();
    // console.log('MD5:'+PromiseMdDigest);
    return PromiseMdDigest;
  }).then(digestOutput => {
    let mdOutput = digestOutput;
    console.info(TAG+'Result:' + mdOutput.data);
    // 转成16进制
    let buf=buffer.from(mdOutput.data);
    console.log(TAG+'Hex222：'+buf.toString('hex'));
    let mdLen = md.getMdLength();
    console.info(TAG+'MDlength: ' + mdLen);
    // 转成base64
    let base64=new util.Base64Helper;
    let resBase64=base64.encodeToStringSync(mdOutput.data)
    console.log(TAG+'base64:'+resBase64)
  }).catch((error: BusinessError) => {
    console.error('error:' + error.message);
  });
}
