Topic: Don't have RSA

I wrote the server and client by myself. I tested it with my own certificate chain and verified the server and client handshake. My server has a 4-layer certificate chain, including the root certificate, intermediate certificate 1, intermediate certificate 2, and leaf certificate. I checked the log and it reported: Don't have RSA. Has anyone encountered this problem? I will attach the logs of my server and client.

Re: Don't have RSA

Hi chenkanghao001,

Here is a relevant piece of code that shows up in your debug message: 

        if (CipherRequires(first, second, REQUIRES_RSA)) {
            WOLFSSL_MSG("Requires RSA");
            if (ssl->options.haveRSA == 0) {
                WOLFSSL_MSG("Don't have RSA");
                return 0;
            }
        }

Can I ask you how you configure and build wolfssl? Can you let us know what configuration flags you use? 

Also, can you give us some hints as to how you initialize your server and client?

I ask these things because perhaps you are disabling RSA somehow.

Warm regards, Anthony

Re: Don't have RSA

There is another possibility that the root cause of your failure is here: 

 wolfSSL Leaving EccVerify, return -330

Can you please also share your certificates and what ECC curves you share in those certificates?

Re: Don't have RSA

I think I messed up the code yesterday. I restarted my computer today and rewrote the experiment. It works. Sorry to disturb your time.

Re: Don't have RSA

Good to know!  Glad you got it resolved.  Can you let us know a bit about yourself?
Where are you located?
What are your goals?
Is the nature of this project academic, commercial, or personal?
We love knowing how our code is being used and any information you are willing to share helps us to better understand our user base.

Warm regards, Anthony

Re: Don't have RSA

Hello

I am currently testing this for personal use. I will test some features that are not available in mbedtls
