HarmonyOS RSA加密失败问题？

发布于

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

该报错信息code=401 message=“create X509Cert failed”，错误原因是非法入参
