HarmonyOS 关于MD5算法的问题

/**********
 * 获取MD5值的方法
 */
static getMd5String(content: Uint8Array): Promise<string> {
  return new Promise((resolve, reject) => {
    let md = cryptoFramework.createMd("MD5");
    let md5str: string;
    md.update({ data: content });
    md.digest((err, mdOutput) => {
      if (err) {
        reject(err);
      } else {
        md5str = Md5Util.uint8ArrayToHexStr(mdOutput.data);
        resolve(md5str);
      }
    });
  });
}

static uint8ArrayToHexStr(data: Uint8Array): string {
  let hexString = "";
  let i: number;
  for (i = 0; i < data.length; i++) {
    let char = ('00' + data[i].toString(16)).slice(-2);
    hexString += char;
  }
  return hexString;
}

用此方法生成的MD5值和其他系统、JAVA生成的值，很大概率不一样，请问这个怎么解决。

可以参考下面的处理方式：

// 字节流转成可理解的字符串
function uint8ArrayToString(array: Uint8Array) {
  // 将UTF-8编码转换成Unicode编码
  let out: string = "";
  let index: number = 0;
  let len: number = array.length;
  while (index < len) {
    let character = array[index++];
    switch (character >> 4) {
      case 0:
      case 1:
      case 2:
      case 3:
      case 4:
      case 5:
      case 6:
      case 7:
        out += String.fromCharCode(character);
        break;
      case 12:
      case 13:
        out += String.fromCharCode(((character & 0x1F) << 6) | (array[index++] & 0x3F));
        break;
      case 14:
        out += String.fromCharCode(((character & 0x0F) << 12) | ((array[index++] & 0x3F) << 6) | ((array[index++] & 0x3F) << 0));
        break;
      default:
        break;
    }
  }
  return out;
}
