Hi everyone, at the recent OpenSSL Conference held in Prague, I got to know about the new OpenSSL project, Jostle (https://github.com/openssl-projects/openssl-jostle) - a Java-based provider that brings the OpenSSL native cryptographic library into the Java ecosystem. I thought to give it a try and deployed it in a VM. I have also recorded the complete deployment and steps and would like to share those resources with everyone who wants to give it a try:

Thanks @Shubham Kumar ! It looks interesting! I think it would be interesting also to see "Jostle in action" after building and testing it: how do you plan to use Jostle in your research? can we see an example of a Java application using Jostle for its crypto backend?

Apologies for the late follow-up; I didn't receive any email. Sure @Nicola Tuveri , actually, I am planning to use Jostle to see its performance against Bouncy Castle's implementation, but I was a little busy lately, so I will keep you updated here once I get any updates.
