HarmonyOS rsa加密报错

出现该报错信息请检查，SDK版本与镜像版本是否匹配。

rsaEncrypt(message: string): Promise<string> {
  return new Promise(async (resolve: (value: string) => void,
    reject: (reason?: Error) => void) => {

  try {
  let rsaGenerator = cryptoFramework.createAsyKeyGenerator('RSA512');
  let cipher = cryptoFramework.createCipher('RSA512|PKCS1');
  let base64Help = new util.Base64Helper();
  let pubKey = base64Help.decodeSync(this.certPublicKey);
  let pubKeyBlob: cryptoFramework.DataBlob = {
    data: pubKey
  };


  let keyPair = await rsaGenerator.convertKey(pubKeyBlob, null)
  await cipher.init(cryptoFramework.CryptoMode.ENCRYPT_MODE, keyPair.pubKey, null)
  let input: cryptoFramework.DataBlob = {
    data: this.stringToUint8Array(message)
  };
  const base64 = new util.Base64Helper()
  const result = base64.encodeToStringSync(input.data)
  console.log(result)
  // let result = await cipher.doFinal(input)
  // let resultData = base64Help.encodeToStringSync(result.data)
  // resolve(resultData)

} catch (err) {
  resolve(message)
}
})
}

使用RSA|PKCS1，明文长度 要小于 密钥长度/8 - 11
