HarmonyOS 鸿蒙Next cryptoFramework库AES CBC解码出来时乱码

static aesCBCDecrypt(encrypttext) {
  let cipherAlgName = 'AES128|CBC|PKCS7';
  let symKeyGenerator = cryptoFramework.createSymKeyGenerator('AES128')
  let ivParam: cryptoFramework.IvParamsSpec = {
    algName: 'IvParamsSpec',
    iv: {
      data: this.stringToUint8Array("bc3f07fbe54c4b90", 16)
    }
  }
  var cipher;

  return symKeyGenerator.convertKey({
    data: this.stringToUint8Array("8985b2c4fb1900cf", 16)
  }).then(symKey => {
    try {
      cipher = cryptoFramework.createCipher(cipherAlgName);
      console.info(`xx cipher algName: ${cipher.algName}`);
    } catch (error) {
      console.error(`xx createCipher failed, ${error.code}, ${error.message}`);
      return null
    }
    return cipher.init(cryptoFramework.CryptoMode.DECRYPT_MODE, symKey, ivParam)
      .then(() => {
        let base64 = new util.Base64Helper();
        let result = base64.decodeSync(encrypttext);
        return cipher.update({
          data: result
        })
      })
      .then(output => {
        let result = this.uint8ArrayToString(output.data)
        return new Promise(resolve => {
          resolve(result)
        })
      }).catch(err => {
        return new Promise((_, reject) => {
          reject(err)
        })
      })
  }).catch(err => {
    return new Promise((_, reject) => {
      reject(err)
    })
  })
}

使用cryptoFramework解码，到返回发现还是乱码

如果把cipher.update修改为cipher.dofinal就直接报17630001错误了
