Hello,

I was looking for benchmarking the execution time of Elliptic Curve based Diffie Hellman of the OpenSSL implementation in C just for my own purpose of understanding.

A few more specifics would be helpful here.

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


||I also tried this code ->

The code over here gives me a bunch of error

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

Is there any other reliable source that has been used before ? If someone knows can you please forward me or let me know? That would be extremely helpful. Thank you for your patience.

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