How to Build Library for OpenSSL Engine Support
Closed this issue · 1 comments
Is there a newer guide on how to add support to the library for using the ATECC as an engine?
I am trying to use ATECC with OpenSSL, and also noticed there is a repository called cryptoauth-openssl-engine. What is the purpose of that repo?
I have defined ATCA_OPENSSL=ON when I build the libcryptoauth library. I then tried to load that using the openssl engine commands, and I get some errors. Does this repo contain the entire source code for use in the openssl engine?
Here are the errors that I get when I try to load the library:

What are the steps I need to get it working?
The project you reference has the following as it's description:
DEPRECATED: Use https://github.com/MicrochipTech/cryptoauthlib/wiki/PKCS11-Linux-Setup
Which explains how to set up this library for use with OpenSSL.
