Expand description

\brief This function sets up an ECDH context from an EC key.

             It is used by clients and servers in place of the
             ServerKeyEchange for static ECDH, and imports ECDH
             parameters from the EC key information of a certificate.

\see ecp.h

\param ctx The ECDH context to set up. This must be initialized. \param key The EC key to use. This must be initialized. \param side Defines the source of the key. Possible values are: - #MBEDTLS_ECDH_OURS: The key is ours. - #MBEDTLS_ECDH_THEIRS: The key is that of the peer.

\return \c 0 on success. \return Another \c MBEDTLS_ERR_ECP_XXX error code on failure.
