WARNING: You are using pip version 20.3.1; however, version 21.0 is available.
You should consider upgrading via the 'c:\programs\python\python371\python.exe -m pip install --upgrade pip' command.In my hardware I am using Wolfssl in C.
I tried to install Wolfssl python library using the given commands in the below link but failed to install due to unknown issues. So I wrote my server using OpenSSL (I am ready to come back to Wolfssl if you help me in installing)
https://github.com/wolfSSL/wolfssl-py
The software that I am using on my device is able to communicate with Azure cloud without any issues. The only change I have done to my working software is the IP address to which it has to contact. So I feel that there are no issues with my device software.
I tried to print the Ciphers supported by the Server using the below command "print(context.get_ciphers())" and the result is attached
And the ciphers that my hardware device is supporting is attached. Can you please help how to add more Ciphers to my device?
In the link you mentioned, it looks very easy to remove/add features. But in code, it looks very hard.
Please help me in resolving the issue.
I am having Openssl based Client and Server in python. I am able to communicate between these scripts without any issue. But when I replace the python client with my hardware device (which is successfully connecting to the Azure network), I am getting an error as "No shared cipher".
Using Wireshark I did some analysis. In a successful connection scenario, the Server is using Cipher suite 0xC030(observed from Server Hello). Which is not enabled in my hardware. I want to know how to enable a cipher in the Wolfssl library.
Thank you for your reply.
Code what I mentioned is written by seeing the example. I didn't see much difference.
For confirmation, I will replace it with your code and confirm.
As part of the project, I am trying to connect the Azure cloud. I can communicate with Azure cloud with the socket in blocking mode without any issues. But when I tried to connect in a Non-blocking mode, it is returning SOCKET_ERROR_E.
I did some more analysis and found out that function "recv(pal_socket_id, buf, sz, flags);" from BSD layer returning -1 because of which we are getting SOCKET_ERROR_E.
I am trying to connect to port 443.
Pasted the code below, in which I failed to make wolfssl_connect function success.
I am getting SOCKET_ERROR_E for wolfSSL_get_error function.
Can anyone help?
