Could not determine kind of name for C.WC_SHA512_DIGEST_SIZE about go-wolfssl HOT 8 CLOSED

Hi @cody0704,
Thank you for your interest in wolfSSL!!
From your message above, I noticed that you did not mention any calls like this:

go get -u github.com/wolfssl/go-wolfssl 

Such a step is documented in the README.md file here:

https://github.com/wolfSSL/go-wolfssl/blob/master/README.md

Please let me know if this helps.
Can you please let us know more about your project and what you are trying to accomplish?

Warm regards, Anthony

Hi @anhu,

Thank you for your response.

I apologize for not documenting the complete installation process I followed.
Rest assured, I did proceed according to the steps outlined in 'https://github.com/wolfSSL/go-wolfssl/blob/master/README.md'.

This included executing the following command:

go get -u github.com/wolfssl/go-wolfssl 

I then continued to follow the instructions for compilation, but encountered the problem shown in the attached picture:

Experiment

I am conducting an experiment where I aim to perform SSL offloading using the Intel QAT Card 8970 in conjunction with wolfssl and intel qat. This is due to the lack of hardware offloading capabilities in crypto/tls.

Hi @anhu ,

I've managed to resolve the issue. After reinstalling and recompiling, I no longer encountered the Could not determine kind of name for C.WC_SHA512_DIGEST_SIZE problem. However, a new issue arose: ./server: error while loading shared libraries: libwolfssl.so.35: cannot open shared object file: No such file or director.

I was able to address this problem by adding the following environment variable:

export LD_LIBRARY_PATH="/usr/local/lib"

Complete Steps

Install wolfSSL

git clone https://github.com/wolfSSL/wolfssl
./autogen.sh
./configure
make
sudo make install
export LD_LIBRARY_PATH="/usr/local/lib"

Install wrapper module

go get -u github.com/wolfssl/go-wolfssl

Test Example

cd go-wolfssl/examples/server
go build server.go

cd go-wolfssl/examples/client
go build client.go

Thanks,

Hi Cody, I see from your output that you were successful. This is great news.

I am conducting an experiment where I aim to perform SSL offloading using the Intel QAT Card 8970 in conjunction with wolfssl and intel qat.

Very interesting!! May I ask, is this a personal, academic or professional experiment?

Warm regards, Anthony

Cody? Can you let me know a bit about your project?

Cody? Can you let me know a bit about your project?

I just returned from a holiday, and I apologize for only responding to you now.

This is a professional experiment.

As previously mentioned, Golang's crypto/tls does not support HW Offload, and the computation in crypto is very resource-intensive, which may result in overall poorer performance. Therefore, I am trying to implement TLS Offload through wolfSSL + Intel QAT.

I am planning to apply this to a DNS over TLS service. Previously, we used Nginx for SSL termination before passing it into Golang, so I want to experiment with go-wolfSSL to see if it can offer a better solution.

If this solution is successful, I would be more than happy to share it, but I am still setting up the environment at the moment and will need some time before I can start developing.

That would be most excellent! I'd love to know how it goes. You can send your results to [email protected] . Please do keep me updated with your progress.

Now that you have found success, I will proceed to close this ticket.
