Hi,

No experience yet with that class but from the looks of it, it's drop in replacement for QTcpServer. So I would say that what you will have to take care of is the certificate side. Either use an official provider or if you create your own certificate, be ready to deploy them.

@dheerendra said in Encrypt/decrypt data with QCA:

Your idea was to encrypt using RSA public key and decrypt using the private key. If this is the case what you are doing correct. Just that you read the keys from key.pem.

Yes, that's what I want to do.
So I guess this is solved. Thank you very much for your help!

@ekkescorner I only now read your username. Sorry for treating you as "not an expert" in network and/or password encryption.

I think you still have 2 options apart from OpenSSL:

Use Android's built in encryption with QAndroidJniObject: https://www.example-code.com/android/rsa_encryptstrings.asp use CryptoC++ https://www.cryptopp.com/wiki/RSA_Cryptography

thx for this worthful info - will try CryptoC++ - need solution for Android and iOS

Then you should take a look at the SQLCipher project. AFAIK, you can also find instructions to build a Qt SQL plugin with it to use in your project.

@Leonardo I think it's for *nix systems, I want it in windows

I have. Usually all my projects get inspired by either the examples or some other project that someone has put on the web. Its just that sometimes I have trouble moving them to the next level, just like with this one.
