Native层回传的公钥数据应用于ets文件导致崩溃

Native层采用 
ohResult = OH_Huks_GenerateKeyItem(&aliasBlob, generateKeyParamSet, nullptr); 
ohResult = OH_Huks_ExportPublicKeyItem(&aliasBlob, generateKeyParamSet, &publicKey); 
生成并导出RSA2048公钥294字节。 
但在ets层采用 
let pkBlob: cryptoFramework.DataBlob = { data : resultTemp.data }; 
let rsaGenerator: cryptoFramework.AsyKeyGenerator = cryptoFramework.createAsyKeyGenerator(“RSA2048”); 
rsaGenerator.convertKey(pkBlob, null, (err, keyPair) => { 
  if (err) { 
    AlertDialog.show({ message: ‘Convert keyPair fail’ }); 
    return; 
  } 
}) 
构造公私钥对用于加密时app崩溃。 
错误信息如下：
