We do the below for this operation:
1How we convert public part of 'EVP_PKEY' structure to 'unsigned char*
//Extract a public key from a PKEY struct.
ec_copy_public(EVP_PKEY *pKey, uint8_t *keybuf)
EC_KEY*pEcKey;
uint8_t encoded_key[MAX_KEYLEN_X962];
uint8_t
*Guessing the context that is sent to EVP_PKEY_derive_set_peer is
initialized/created with a pkey belonging to different group. *
*In other words, EC keys of both parties in DH are not of the same group. *

Hi all,
I was trying to use ECDH (in OpenSSL v1.0.1f) for a project, and after
generating the EVP_PKEY structure, I needed to extract its public key and
send it over to the other party. I was unable to find a straightforward way
which worked for me.
What I tried was this:
EVP_PKEY*
