When encrypting on windows and decrypting on linux, something went wrong #30

Closed AugustToko closed 3 years ago

AugustToko commented 4 years ago

I do n’t know why this happens, can someone help me?

On Win

  var publicKeyFile = File('D:\\Web\\api_test\\files\\rsa_public_key.pem');

  var publicStr = await publicKeyFile.readAsString();
  publicKey = rsaC.parseKeyFromString(publicStr);

  var eData = rsaC.encrypt('123456789', publicKey);
  var result = await Dio().post(url, data: {'data': eData});
  print(result);

On Linux

    final RsaCrypt rsaC = RsaCrypt();
    RSAPrivateKey rsaPrivateKek;

    final pemFile =
        File('/var/www/lingyun_server/keys/rsa_private_key_pkcs8.pem');
    final str = await pemFile.readAsString();
    rsaPrivateKeyWk = rsaC.parseKeyFromString(str)
    // data is passed by post (application/json) request
    print(rsaC.decrypt(data.eData, rsaPrivateKeyWk));

I'm on mobile rn, will take a look later.

AKushWarrior commented 4 years ago

Fist comment: instead of using parseKeyFromString on the stringified file, you should use parseKeyFromFile and pass the filename.

AKushWarrior commented 4 years ago

Can you try that and see if it changes anything?

AugustToko commented 4 years ago

Sorry for not being able to reply in time. Even if I use parseKeyFromFile, the effect is the same. After testing, encryption and decryption are normal on the same platform. In addition, when I tried parseKeyFromString, the newline character (\n) was unified, but it didn't work. By the way, now I use encrypt: ^ 3.3.1 and it works well.

AKushWarrior commented 4 years ago

Okay, thanks for the info. Will take a look!

AKushWarrior commented 4 years ago

This is very strange, but I don't have a Windows machine or a Linux machine. I'll have to shelve this for now, sorry.

AKushWarrior commented 3 years ago

Since RSA is being deprecated (see README), this is irrelevant.
