HarmonyOS RSA加密失败问题

其他系统代码:

KeyFactory keyFactory = KeyFactory.getInstance("RSA");
byte[] bytePublicKey = Base64.decode(publicKey, 0);
X509EncodedKeySpec x509EncodedKeySpec = new X509EncodedKeySpec(bytePublicKey);
Key publicK = keyFactory.generatePublic(x509EncodedKeySpec);
String transformation = "RSA/ECB/PKCS1Padding";
Cipher cipher = Cipher.getInstance(transformation);
cipher.init(1, publicK);

HarmonyOS 代码:

 static async encryptByPublicKey(data: string) {
  let base64Helper = new util.Base64Helper()
  let keyGenerator = cryptoFramework.createAsyKeyGenerator('RSA1024')
  let pubKey = await RsaEncryptUtil.genPublicKeyPairByData()
  let keyPair = await keyGenerator.convertKey(pubKey.getEncoded(), null)
  let cipher = cryptoFramework.createCipher('RSA|PKCS1')
  await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, keyPair.pubKey, null)
  let inputBlob: cryptoFramework.DataBlob = {
    data: base64Helper.decodeSync(data)
  }
  let cipherText = await cipher.doFinal(inputBlob);
  return base64Helper.encodeToString(cipherText.data)
}

static async genPublicKeyPairByData(): Promise<cryptoFramework.PubKey> {
  RsaEncryptUtil.key = ContextUtils.getContext().resourceManager.getRawFileContentSync(RsaEncryptUtil.fileName)
  let cerData = new util.Base64Helper().decodeSync(RsaEncryptUtil.key)
  let encodingBlob: cert.EncodingBlob = {
    data: RsaEncryptUtil.key,
    data: cerData,
    // 根据encodingData的格式进行赋值，支持FORMAT_PEM和FORMAT_DER和FORMAT_PKCS7
    encodingFormat: cert.EncodingFormat.FORMAT_PEM
  };
  let x509Cert = await cert.createX509Cert(encodingBlob)
  return x509Cert.getPublicKey()
}

其中本地文件内容为公钥字符串长度216位无边界符，尝试了 cert.EncodingFormat所有枚举类型均失败

错误代码为：code=401 message="create X509Cert failed"

根据官方文档得知原因为格式错误 但是该格式在上述其他系统代码中可以正常运行

帮忙确认一下是其他系统转HarmonyOS 的代码错误还是官方目前不支持相关格式
