<p>Hey Hi,</p>
<p>I'm using 1.0.2n version of openSSL currently. </p>
<p>I'm using it on ubuntu 16.04, processor is i7 - 6700 Skylake.</p>
<p>Actually I understand that the code <a href="https://wiki.openssl.org/index.php/Elliptic_Curve_Diffie_Hellman" class="x_OWAAutoLink" id="LPlnk409965">https://wiki.openssl.org/index.php/Elliptic_Curve_Diffie_Hellman</a> has omitted t<span style="font-family:sans-serif; font-size:12.7px">he
details of how to obtain the other party's key (the peer key) . </span></p>
<p><span style="font-family:sans-serif; font-size:12.7px">So is there any code available online which can be used to benchmark the execution time of the ecdh implementation of OpenSSL ? Is someone aware of that ?</span></p>
<p><span style="font-family:sans-serif; font-size:12.7px"><br>
</span></p>
<p><span style="font-family:sans-serif; font-size:12.7px">Then please let me know.</span></p>

A few more specifics would be helpful here.<br>

Your results here would be portable across systems however one would<br>
need to know the nature of the build and the architecture. I often<br>
single step through functions and thus use non-optimized debug builds<br>
which are vastly slower than a regular optimal build. Also the asm code<br>
simply does not exist on some architectures like sparc ( non T4 ) or<br>
some older powerpc types.<br>

That isn't too clear. How are you calling ecdh() and with what test data?<br>

Hey there UofW type, what rev of openssl are you using? Should I assume<br>
that you have "OpenSSL 1.1.0g 2 Nov 2017" on some reasonable<br>
architecture?<br>
