OpenSSL only supports ECDH (for key exchange) and ECDSA (for digital
signatures) for elliptic curve keys,
Is there a way to encrypt a file using the openssl command with an
elliptic curve public key? Here's what I get when I try using OpenSSL
1.1.0c :
normg>./openssl pkeyutl -encrypt -pubin -inkey secp256k1-public-key.pem
