Is it possible for someone to post a working example?  I have written many test and examples, and I just can't seem to get 2 secrets that are alike with this method.

I am following this; https://sandilands.info/sgordon/diffie-hellman-secret-key-exchange-with-openssl

With the console, it works great. With openssl_dh_compute_key it does not work.
