No, there's no command like that.  Most of the command line tools for
public-key crytography are just for generating and handling keys, but
not for actually using them for the respective cryptographic
operations -- you'd have to use some program on top of the OpenSSL
library for that.

ECC DH

2008-07-23 Thread Keith Ellul
Hi,

I'm new to this list -- I hope that this is the right place for this question!

Basically, I see that ECDH is part of openSSL.  I have an ECC keypair, and I 
have someone else's ECC public key.  I want to use ECDH to agree on some key 
material.  Can I do this from the command line (ie, using the openSSL 
executable)?  I was hoping for an "openssl ecdh" command, but, there doesn't 
appear to be one.  I've read through the docs for "ec", "ecparam", and 
"dhparam", as well as various forum posts, and I can't find anything.  Is there 
a command (or set of commands) to do what I want to do?

Thanks in advance for any help,

Keith
