Hello :-)

I need to secure gRPC connection by using OpenSSL v3 having private key(s) in TPM.

Can I just configure OpenSSL with TPM provider, and then use a handle of private key, which is stored in TPM, in my C++ code?

Is TPM usage transparent for gRPC?

Thank you for answer or a hint how to integrate these three components in C++ program,

Raimund

I have not found support of OpenSSL provider in gRPC.

gRPC supports OpenSSL engine, which is already deprecated for OpenSSL v3.

I am facing the same issue as well. Have you found any solution?
